Whiteleaf Hill and Brush Hill, Princes Risborough

Whiteleaf Hill rises sharply above Princes Risborough on the Chiltern escarpment, and this 6.8 km circular climbs steeply through mixed woodland to open chalk downland where a Neolithic cross-dyke barrow and the Whiteleaf Cross chalk figure sit above the vale. The route loops across Whiteleaf Hill and into the Brush Hill Nature Reserve — a BBOWT-managed site of ancient chalk grassland and juniper scrub — before descending through tall beeches on the escarpment slope. The 224 metres of climbing is concentrated in the initial ascent, which is steep and sustained on chalk and flint paths. The chalk grassland at the summit is botanically rich and carries the sweet, dry mineral smell of undisturbed chalk turf, with orchids and aromatic herbs in the warmer months.

This dog friendly walk has limited off-lead potential due to high livestock risk — sheep graze the open downland, and the chalk grassland is ecologically sensitive with ground-nesting birds during breeding season. Leads are needed on the hilltop sections and through any grazing areas. The steep woodland ascent provides excellent physical exercise, and the beech woodland on the descent is atmospheric with dappled light filtering through the canopy onto a carpet of copper leaves in autumn. The chalk and flint paths can be slippery when wet, so confident footing is needed from both dog and walker. The views from the summit across the Vale of Aylesbury are extensive, and the combination of ancient archaeology, rich botany and dramatic escarpment scenery makes this walk feel much bigger than its distance suggests.
