The E slopes into Glen Derry are generally craggy and steep and should be avoided whereas the W slopes generally have more moderate inclines and fewer rocky outcrops.

The summit cone is composed of boulders, the upper slopes are of short grass and the lower slopes of grass and heather.

The normal access routes are from Glen Luibeg to the S or from Loch Etchachan to the NW.

Driesh has a short S ridge (Shank of Driesh) and a longer E ridge which connects to Mayar via a narrow col, then turns S to terminate in Hunt Hill (734m), overlooking Glen Prosen. The slope of these ridges is moderate to gentle.

Access is normally via the path on the Shank of Drumfollow, or on the N ridge.

The traverse of the ridge follows the scalloped rims of the corries between peaks. The ridge may be climbed in two sections E and W but individual peaks are not easily accessed and do not require individual descriptions.

Druim Shionnach is in the E section and is unusual in that it offers an alternative ascent route via its N ridge which has a path leading down to Loch Cluanie.
