Loch Lomond & The Trossachs Midges in January — Risk, Peak Times, Kit
Effectively no midges. Plan freely. The first proper midge country going north from Glasgow. Loch Lomondside, the Trossachs lochs and the Arrochar Alps all hold strong populations. The east shore at evening in July is a textbook case of why head nets exist.

Tactical notes
January in Loch Lomond and the Trossachs is the off-season for visitors and the off-season for midges. The famously busy West Highland Way east-shore path between Drymen and Rowardennan — the canonical July midge stretch — is quiet, wet, and entirely free of biting insects. Same for the Arrochar pubs, the Aberfoyle car parks and the Loch Katrine pier: empty, atmospheric, and zero insect tax.
The Arrochar Alps and the Crianlarich Munros are in proper winter mode. [Ben Lomond](/hillwalking/munros/ben-lomond) — the most southern Munro and Scotland's most-walked summit in summer — sees its quietest weeks of the year in January and gives a serious winter day in full conditions. [Beinn Ime](/hillwalking/munros/beinn-ime), [Beinn Narnain](/hillwalking/munros/beinn-narnain), [Ben Vane](/hillwalking/munros/ben-vane) and [Ben Vorlich](/hillwalking/munros/ben-vorlich-arrochar-trossachs) are all serious Munros in January conditions, reachable from the Arrochar & Tarbet station on the West Highland Line.
[The Cobbler (Ben Arthur)](/hillwalking/corbetts/the-cobbler) above Arrochar is the best winter Corbett in Britain when conditions cooperate — the three summits give classic Scottish III/IV climbing on the centre and north peaks, while the south peak is a walk-up. The Crianlarich Munros — [Ben More](/hillwalking/munros/ben-more-arrochar-trossachs) and [Stob Binnein](/hillwalking/munros/stob-binnein), [Cruach Ardrain](/hillwalking/munros/cruach-ardrain), [Beinn Dubhchraig](/hillwalking/munros/beinn-dubhchraig) and [Ben Oss](/hillwalking/munros/ben-oss) — all give long winter days reachable by train. The Trossachs viewpoint hills around [Ben Venue](/hillwalking/grahams/ben-venue) and the Loch Ard forest give shorter family-friendly winter walks. Head net stays at home; pack ice axe and crampons for the higher tops.
