The Argyll Sea Kayak Trail: Complete 150km Paddling Guide

Quick Summary

• 150km of sheltered coastal kayaking from Oban to Helensburgh through Argyll's sea lochs, the Crinan Canal, Loch Fyne and the Kyles of Bute — Scotland's only long-distance sea kayak trail
• Most paddlers take 7-10 days, wild camping on beaches and headlands, with resupply available in coastal villages every 1-2 days
• Intermediate skill level — sheltered water for most of the route, but tidal planning is essential at key headlands and crossings, and open-water sections demand confident boat handling
• Plan your paddling hours — our Daylight Hours Planner shows how much usable light you have at Argyll latitudes, which matters when tidal windows dictate your schedule

The Argyll Sea Kayak Trail is the quiet achievement of Scottish sea kayaking. While the Outer Hebrides and the Small Isles get the expedition glory, this 150km route from Oban to Helensburgh threads through some of the most sheltered and beautiful coastal water in Britain without ever asking you to make an open-ocean crossing. It follows the logic of the coastline — sea lochs, sounds, canals and island channels — and it works as a genuine long-distance trail with a beginning, an end, and a clear direction of travel.

The trail was developed by the Scottish Canoe Association and is described in a dedicated guidebook. It is not waymarked on the water — you navigate by chart, compass and the coastline itself — but the route is well-documented and the infrastructure of launch points, landing spots and wild camping sites is real.

Quick Answer: The Argyll Sea Kayak Trail runs approximately 150km (93 miles) from Oban south to Helensburgh, passing through Craobh Haven, Ardfern, the Crinan Canal, Ardrishaig, Loch Fyne, Portavadie, the Kyles of Bute, Colintraive and the eastern shore of Loch Long. Most paddlers take 7-10 days, wild camping throughout with resupply available in villages along the route. The trail suits intermediate paddlers — Paddle UK 3-star equivalent — who are comfortable with tidal planning, open-water crossings of 1-2km, and multi-day self-sufficiency. The season runs May to September, with June offering the longest days and most reliable conditions.

What is the Argyll Sea Kayak Trail

The ASKT is Scotland's only designated long-distance sea kayak trail. The Argyll coast is indented with so many sea lochs, sounds and island channels that you can paddle 150km without ever being more than a few hundred metres from shore for most of the route.

The trail runs south and east from Oban to Helensburgh. It is not a single line on a chart — there are variants at several points — but the core route passes through:

• Oban to Craobh Haven — island-hopping south through the Slate Islands
• Craobh Haven to Ardrishaig — via Ardfern, Loch Craignish and the Crinan Canal
• Ardrishaig to Otter Ferry — down the length of Loch Fyne
• Otter Ferry to Colintraive — through the Kyles of Bute
• Colintraive to Helensburgh — via Loch Striven, the Firth of Clyde and the Gareloch

The total distance varies from 140-160km depending on route choices, diversions and how much island exploration you add. The official guidebook describes it as approximately 150km.

Route overview: section by section

Oban to Craobh Haven (25km, 1-2 days)

The trail begins at Oban — the sea kayaking capital of the west coast, with shops, accommodation and the best range of paddling providers in Scotland. From Oban you paddle south through the Sound of Kerrera, sheltered by the island of Kerrera to the west. This is a gentle start — the sound is calm in most conditions and offers views across to Mull.

South of Kerrera, the route threads through the Slate Islands — Seil, Easdale and Luing. The tidal streams around Cuan Sound (between Seil and Luing) require careful timing. This is the first section where the tide table matters — Cuan Sound runs hard on springs and should be paddled at slack water or on a favourable stream.

Craobh Haven is a small marina village with a shop and a pub. Good place to resupply and stretch your legs.

Craobh Haven to Ardrishaig (25km, 1-2 days)

South from Craobh Haven through Loch Craignish, past the islands of the Craignish peninsula, and into the entrance to the Crinan Canal at Crinan. Loch Craignish is sheltered and scenic — wooded islands, seal haul-outs and quiet water.

The Dorus Mor tidal race at the southern entrance to Loch Craignish is a serious feature. It runs hard on springs and can produce standing waves and overfalls. Time your passage for slack water or avoid it entirely by taking the inshore route east of the islands.

From Crinan, you enter the Crinan Canal — a 14km portage (or paddle, if permitted) connecting the west coast to Loch Fyne via Ardrishaig. The canal was built in 1801 to save boats the long passage around the Mull of Kintyre, and it serves exactly the same function for kayakers.

The Crinan Canal portage (14km)

The canal has 15 locks and is not always navigable by kayak — water levels and canal traffic vary. Most paddlers portage some or all of the canal using a kayak trolley on the towpath. It is flat, paved and straightforward, but 14km of dragging a loaded sea kayak is a solid half-day. Some paddlers arrange vehicle support for this section.

The canal is scenic in its own way — the towpath runs through woods and farmland between Crinan and Ardrishaig, passing Bellanoch and Cairnbaan. Ardrishaig at the eastern end has a Co-op, a hotel and sits on the shore of Loch Fyne.

Loch Fyne: Ardrishaig to Otter Ferry (35km, 2-3 days)

Loch Fyne is the longest sea loch in Scotland — 65km from head to mouth — and the ASKT follows its western shore south from Ardrishaig. This is open water but sheltered from Atlantic swell by the Kintyre peninsula. The main hazard is wind funnelling down the loch — southerlies can build a significant chop on the fetch.

The western shore passes Lochgilphead (the largest town on the route, full services), then south through quieter water past Castle Lachlan to Otter Ferry. Landing and camping spots are regular along this shore — shingle beaches, grassy headlands and the occasional forestry track leading to flat ground.

Otter Ferry is a tiny settlement with a pub (the Oystercatcher) but no shop. Resupply at Lochgilphead before heading south.

Kyles of Bute: Otter Ferry to Colintraive (20km, 1-2 days)

The Kyles of Bute are the highlight of the trail for many paddlers. These are the narrow tidal channels separating the Isle of Bute from the Cowal peninsula — winding, sheltered, fast-flowing water with wooded shores and views to the Arran mountains beyond.

The East Kyle and West Kyle meet at Burnt Islands — a cluster of small islands in the narrows that create interesting water on the tide. The tidal streams through the Kyles run at up to 3 knots on springs, so timing matters. Paddle with the stream and the Kyles are a joy. Paddle against it and you will not make progress.

Colintraive sits on the eastern shore of the Kyle, with a ferry to Bute and a hotel. The name means "the swimming narrows" in Gaelic — this is where cattle once swam across to Bute.

Colintraive to Helensburgh (30km, 2-3 days)

The final section takes you east and south through the upper Firth of Clyde. From Colintraive, paddle south past Toward Point and into Loch Striven or the wider firth. This section is more exposed than the Kyles — the Firth of Clyde is open water with commercial shipping traffic, and wind can build significant waves on the fetch.

The route follows the Cowal shore south past Dunoon (full town services — the largest settlement since Oban) and then east along the northern shore of the firth. Options include crossing to Helensburgh directly (a 3-4km open-water crossing from Kilcreggan) or hugging the shore around the Rosneath peninsula via the Gareloch. Helensburgh has a train station with direct services to Glasgow — a satisfying end to the trail.

Tidal planning and weather

Tidal awareness is the single most important skill on the ASKT. Three points on the route have serious tidal features:

• Cuan Sound (between Seil and Luing) — runs at up to 4 knots on springs. Paddle at slack water.
• Dorus Mor (south end of Loch Craignish) — a tidal race that produces overfalls and standing waves. Avoid on spring tides or paddle the inshore route.
• Kyles of Bute — up to 3 knots on springs. Use the stream, do not fight it.

Outside these narrows, tidal streams along the Argyll coast are mostly weak (under 1 knot). But wind against tide can still produce rough water — Loch Fyne is notorious for short, steep wind waves when a southerly blows against an ebb tide.

Weather sources:

• Met Office Inshore Waters forecast for the Clyde
• MWIS (Mountain Weather Information Service) for coastal wind
• XC Weather and Windy.com for hour-by-hour wind and swell
• Admiralty tidal stream atlases or apps (Imray, EasyTide) for tidal planning

Check the forecast every morning and plan around wind. A headwind of 15 knots makes progress exhausting. A headwind of 20 knots makes progress impossible in a loaded touring kayak.

When to go

May — long days (16+ hours), quiet water, wildflowers on the headlands. Sea temperature 10-12°C. Some risk of late spring northerlies. Midges start late May.

June — the optimal month. 17-18 hours of daylight, warmest average conditions, calmest seas. Sea temperature 12-13°C. Peak midge season in sheltered bays — bring a head net and repellent for camp.

July-August — warmest sea temperature (13-15°C), peak midge season, school holiday traffic on the water. Conditions are generally good but Atlantic low-pressure systems can bring prolonged rain and wind at any time.

September — shorter days (13-14 hours), declining midges, autumn colours. Sea temperature still 13-14°C (the warmest month for sea temperature is often August-September). Weather becomes less settled — be prepared for weather-hold days.

Avoid October-April. Short days, cold water, winter storms and the absence of other paddlers make the trail unviable for anything other than experienced winter paddling groups.

Kit list for the trail

Boat and paddling kit:

• Sea kayak with bulkhead hatches (day hatches help hugely for access to snacks, charts and camera)
• Spare paddle (split, stowed on deck)
• Spraydeck
• Buoyancy aid (PFD)
• Drysuit or semi-dry suit — sea temperature is 10-15°C; a wetsuit is marginal for multi-day paddling
• Paddle leash
• Towline
• Deck-mounted chart holder or waterproof map case

Navigation and safety:

• Admiralty charts or OS maps covering the route (OS Explorer 359, 358, 357, 363, 362, 347)
• Compass (deck-mounted and handheld)
• VHF radio — essential, not optional. Mobile coverage is patchy to absent along much of the Argyll coast
• Tow float or visible deck flag(affiliate link) for visibility to other vessels
• First aid kit including hypothermia treatment
• Flares (minimum: 2 red hand flares, 2 orange smoke)
• Phone in a waterproof case as backup communication

Camping kit:

• Lightweight tent (freestanding is easier on rocky shores)
• Sleeping bag rated to 5°C minimum
• Sleeping mat
• Stove, fuel and cooking kit
• 10 days of food (or plan resupply at Lochgilphead and Dunoon)
• Water containers (5-10 litres capacity — fresh water is available from streams throughout the route)
• Drybags for all kit inside hatches

Personal:

• Midge head net and repellent (June-August, absolutely non-negotiable on the Argyll coast)
• Sun cream and sunglasses (reflected glare off water)
• Pogies or neoprene gloves for cold mornings
• Camp clothes in a drybag — warm layers for evenings

Wild camping spots along the route

The Scottish Outdoor Access Code gives you the right to wild camp responsibly throughout the route. The best camping spots on the ASKT are:

• South of Kerrera — shingle beaches on the east shore of Kerrera, sheltered from westerlies
• Slate Islands — Easdale and the small islands south of Seil have landing beaches with flat ground above the tideline
• Loch Craignish islands — Eilean Righ and the smaller islands in the loch have sheltered bays with camping ground
• Loch Fyne western shore — regular shingle beaches and grassy headlands between Lochgilphead and Otter Ferry
• Kyles of Bute — the Burnt Islands area and the shores of the East Kyle have quiet beaches away from the road
• Loch Striven — remote, uninhabited western shore with multiple landing and camping options

Camp above the high-tide line (check for seaweed debris marking the spring high-water mark), carry out all waste, and keep fires small and on the foreshore if at all — or use a stove. Many of these beaches are ecologically sensitive, so stick to established landing spots where you can see others have camped before.

The Argyll Sea Kayak Trail guidebook(affiliate link) by Tom Smith and Leonora Smith (Pesda Press) is the essential planning resource. It covers the full route with charts, tidal information, camping spots and practical detail that no online guide can replicate. Buy it before you go.

Skill level required

The ASKT is an intermediate sea kayaking trail — roughly Paddle UK 3-star standard. You need:

• Confident forward paddling in wind and chop — you will encounter days with 10-15 knot winds and short seas on Loch Fyne
• Tidal planning — ability to read tide tables, work out slack water times, and plan passages around tidal gates at Cuan Sound, Dorus Mor and the Kyles
• Assisted and self-rescue — if you capsize in 12°C water with a loaded boat, you need to get back in quickly. Paddle with at least one partner who can perform an assisted rescue
• Chart reading and coastal navigation — following a coastline is straightforward, but identifying headlands, timing passages and reading sea conditions requires competence
• Multi-day camping self-sufficiency — you are carrying everything for 7-10 days, loading and unloading a kayak twice daily, and managing kit in wet conditions
• Weather judgement — knowing when to paddle and when to stay on shore. This is the skill that separates safe paddlers from lucky ones

If you have completed several multi-day kayak trips on sheltered water and can handle moderate conditions confidently, you are ready. If the Argyll Sea Kayak Trail would be your first multi-day paddle, consider a guided trip or a shorter 2-3 day section first.

Getting there and logistics

Start (Oban): ScotRail train from Glasgow Queen Street to Oban (3 hours). Citylink bus from Glasgow or Edinburgh. Oban has accommodation, outdoor shops, kayak hire and ample parking if driving.

Finish (Helensburgh): ScotRail train to Glasgow (45 minutes). Regular service, easy with a kayak trolley to the station.

Kayak transport: If using your own boat, the simplest shuttle is to drive to Helensburgh, park, take the train to Oban, and paddle back to your car. Some paddling providers in Oban offer kayak hire and may arrange end-to-end logistics.

Emergency planning

The Argyll coast is not remote by Scottish standards — you are rarely more than a few kilometres from a road — but mobile phone coverage is unreliable, and the water is cold enough to kill.

VHF radio: Channel 16 for Coastguard. This is your primary emergency communication tool. A handheld VHF reaches the Clyde Coastguard from anywhere on the route.

RNLI stations: Oban, Tighnabruaich and Helensburgh all have RNLI lifeboats. Response times vary but are typically 20-40 minutes on the inner Argyll coast.

Hypothermia is the primary risk. Water temperature of 10-15°C gives you 10-30 minutes of useful swimming ability after capsize, depending on clothing. A drysuit extends this dramatically. Carry spare dry clothing accessible on deck.

Float plan: Leave a detailed plan with a responsible person on shore — daily route, expected campsites, check-in times if phone signal allows. Register your trip with the Coastguard using the CG66 voluntary safety scheme.

Escape points: The ASKT has more escape points than most sea kayak routes — you are rarely more than a day's paddle from a road, village or ferry terminal.

Frequently Asked Questions

How long does the Argyll Sea Kayak Trail take?

Most paddlers take 7-10 days to complete the full 150km from Oban to Helensburgh. Fit, experienced paddlers who push long days can finish in 5-6 days. A relaxed pace with rest days and island exploration stretches to 10-14 days. The biggest variable is weather — a day of 20+ knot headwinds means a day on shore, and this happens at least once on most trips.

Do I need a guide for the Argyll Sea Kayak Trail?

Not if you are an intermediate paddler (Paddle UK 3-star equivalent) with multi-day touring experience and tidal planning skills. The route is well-documented in the guidebook and follows a logical coastline. If this would be your first multi-day sea kayak trip, a guided section or a shorter independent trip (Oban to Craobh Haven, 2 days) is a sensible first step. Sea kayak providers in Oban offer guided ASKT trips.

Can I paddle the Argyll Sea Kayak Trail solo?

Technically yes — it is legal and the route is sheltered enough that experienced solo paddlers do complete it. However, solo sea kayaking requires advanced self-rescue skills (a reliable roll or confident solo re-entry), weather judgement, and acceptance of the risk that a capsize with no partner in cold water is a serious emergency. The standard recommendation is to paddle with at least one partner.

What is the hardest section of the ASKT?

The tidal sections at Cuan Sound and Dorus Mor are the most technically demanding. The open water on Loch Fyne and the Firth of Clyde can be challenging in wind. The Crinan Canal portage is physically hard but not technically difficult. For most paddlers, the mental challenge of sustained multi-day paddling and camping — wet kit, tidal logistics, weather decisions — is harder than any single section.

Can I do the Argyll Sea Kayak Trail in sections?

Yes, and this is an excellent way to experience the trail. Oban to Ardrishaig (3-4 days), Ardrishaig to Colintraive (3-4 days), and Colintraive to Helensburgh (2-3 days) are natural sections with road access at each end. Bus and ferry connections make shuttle logistics feasible for each section independently.
