Marilyn · Arran
A' Chruach
The Stack, the high point of southern Arran's rolling moorland country. Quite different in character to the granite peaks of north Arran — gentle moorland whalebacks here rather than rocky aretes — with sweeping panoramas over the Firth of Clyde to Ailsa Craig.

Standard route
rough grassland 55% · heather 30% · rocky summit 15%
Most parties start from the Ross Road and follow forestry roads inland before striking up the open moor to the summit trig. A relaxed half-day of around 10km return; an obvious objective to combine with a beach walk on the Arran south coast.
Terrain
Forestry road on the lower section is firm; thereafter open moorland with patches of bog. The summit gives short-cropped grass and easy walking once the heather is left behind.
In winter
Snow lies only briefly on these southern Arran moors but persistent rain leaves the bogs saturated for much of the winter. Pick a settled day and add gaiters.
