Between the summit and a trig point (1 mile (1.6 km) to the south west) lies Birks Tarn, which is one or the largest tarns in the Yorkshire Dales.

It is prevented form leaking through the bedrock underneath by its impermeable layers and additionally held back by the peaty soil.

[4] The section at the top of the fell is a wide ridge that offers excellent walking and "outstanding views".

[7] The name Birks derives from the Old Norse word for birch; the lower slopes of the hill used to be covered in them.
