A glacier carved out this valley during the last ice age.
As it melted, about 18,000 years ago, it exposed the steep rock walls of Craig Cerrig Gleisiad.
Some time later, a catastrophic landslide cascaded millions of tonnes of rock from these crags down the slopes.
Archaeological remains found on the reserve show that the area has been inhabited for many thousands of years.
Apart from Iron Age huts there are also the remains of a Roman road and later farm settlements.
The steep rocky slopes, sharp escarpments and crags are home to rare arctic-alpine plants. These are at their southernmost location in the UK and are not found again until the Alps.
Arctic-alpine wildflowers grow on the north-facing rocky cliffs. They include purple saxifrage, mossy saxifrage, serrated wintergreen and green spleenwort.
The cliffs are, in effect, a vertical woodland with trees and shrubs of hawthorn, rowan, ash and rare whitebeams.
There is a also rich variety of wildflowers and many different mosses and liverworts.
Early spring to mid-summer is a great time to see the reserve’s spectacular range of wildflowers and also its birdlife including peregrines, kestrels, red grouse and rare ring ouzels.
In August and September the hillsides come alive with the glow of heather.
