Narnain Boulders


Start : Succoth car park, (G83 7AP). Grid ref. NN 29489 04993

(D/A) From Succoth car park head out the main entrance to reach the A83.

(1) Cross the A83 picking up a track at the other side, signposted "Argyll Forest Park".

Follow the path as it zig zags uphill.

(2) At 100m elevation you'll reach a forestry track at a bench. Turn left (SW).

(3) Almost immediately turn right (NW) onto another footpath zig zagging uphill.

(4) At 300m elevation the path emerges out the forest beside the Allt a Bhalachain burn.

(5) Continue in a general NW direction for approx 3km with the burn on your left-hand side, passing the Narnain Boulders at 480m elevation.

On a clear day you'll have a good view of Ben Arthur (The Cobbler) ahead to your left and Beinn Narnain to your right.

At the top of the burn you reach Bealach a’ Mhaim where the terrain levels out.

(6) At a path junction at 630m elevation, turn right (N/NE), heading away from The Cobbler, traversing the bealach.

(7) After passing through a gate at 637m elevation, the path begins to ascend towards the summit of Beinn Ime.

(8) Ascend the path for approx 20m, then come off the path and descend the hillside to your right in a general NE direction. Note that the terrain here is extremely steep and challenging (tussocky grass with lots of small water courses to be careful of). Make sure you stay to the left of the Allt Coriegrogain burn as you descend.

(9) You want to aim for a fenceline at 450m elevation on the edge of a conifer plantation. Climb over the fence (no barbed wire) and follow it roughly N, turning right (E) into a clearing in the trees.

(10) You will reach the start of a forestry track.

(11) The forestry track follows the course of the burn for approx 1km where it passes a small dam.

(12) Take the next track on your right (SE). This leads to a ford across the burn may be impassable if the burn is in spat...

(13) After crossing, turn left (E) signposted Glen Loin Loop Arrochar.

(14) Continue on this track for 6.5km to a path junction at 90m elevation where you turn right (SW), ignoring the sign post for the car parks.

After 600m you'll arrive back at the bench from earlier (2). Turn left (SE) to zig zag back down the final section of the hillside to the A83 (1), with Succoth car park just over the other side (D/A)
