Geography.
Two huge volcanic cliffs loom amidst its wooded slopes, where lime trees can be found benefitting from the rock's richness and low acidity. The reserve is the largest oak woodland growing on this type of base in North Wales, and is important for some of Snowdonia’s specialities, such as arctic and alpine plants.
