Walk through Glen Sannox and Glen Rosa Details

A linear route on the Isle of Arran linking Sannox and Brodick via two of the largest glens on the island with an interesting geological feature on route.


From the ferry terminal, take the 324 (via north island) bus and ask for Glen Cottage at Sannox.

Glen Cottage and the start of the route

Pass through the gate to the left of the cottage. Continue on the good path to the graveyard on the left where lies the body of Edwin Rose and a tale of murder and intrigue.

From the graveyard, continue on the track, passing through a gate and cross the Sannox burn via the footbridge. The path rises away from the burn and the glen opens up ahead.

Red deer can often be seen on either side of the glen and golden eagles have been spotted as well.

The good path eventually begins to climb beneath the east face of Cir Mhor with seemingly no exit from the glen. However, after scrambling up some loose rock, the route reaches the base of Winn Dyke, an igneous intrusion of volcanic rock. Erosion has left the harder rock standing proud and it forms a series of steps. In dry conditions it is an easy scramble up the middle of the gulley but if wet, it is probably safer (and easier) to keep to the left hand side.

Do not climb all the way to the top of the gulley but look for an exit on the left which leads up a stony path, emerging onto less steep ground at The Saddle.

The Saddle is a good place for a refreshment stop as the large rocks provide shelter from the wind from all directions. There are good views back down Glen Sannox to the coast and down Glen Rosa.

Leaving The Saddle, the path heads due south and descends to the floor of Glen Rosa where it continues alongside Glenrosa Water.

After passing through a fenced area (to protect the native trees from deer), continue until the bridge which crosses Garbh Alt. This is another good spot for a rest and in hot weather the chilly water may provide some relief for tired feet.

After crossing the bridge continue on the track, passing the camp site on the left. Stay on the surfaced road now until it joins the main B880. Turn left and then right at the junction with the A842 and walk the remaining distance into Brodick.
