Once farmed but no longer inhabited, it is now used for sheep pasture, a public water supply and recreation in the form of fishing and walking.
The bed of the glen ranges in altitude from 228m, at the saddle at UK Grid reference NN819002, to about 20m where it emerges onto the flood plain in Menstrie at NS849970.
An earth embankment seemingly designed to divert compensation water around the north side of the reservoir has been breached so the Menstrie Burn relies for its flow mainly on the streams entering the watercourse below the dam.
The lower (southern) parts of the glen, reached by footpaths from Menstrie, give access to routes to the summits of Dumyat and Myreton Hill.
A gated farm track leads from Menstrie around the eastern and northern flanks of the glen to the ruin of Red Brae (NS842992), near Jerah.
In October 2008, Menstrie Community Council announced a proposal to make access to the glen easier and to install visitor attractions.
Communication began between Tillhill and Menstrie Community Council about adjusting the proposed forest layout to retain access for recreational uses.
