Surrey’s Toughest Climb
Leith Hill stands at 294 metres above sea level, making it the highest point in Surrey. For cyclists, the various approaches to the summit offer some of the most demanding climbing in Surrey. The most popular ascent from the south via Ockley climbs steeply through dense woodland, with gradients touching 16 per cent in places. The road surface is reasonable but narrow, winding past Leith Hill Place — the childhood home of composer Ralph Vaughan Williams — before emerging near the 18th-century tower (built 1765) at the summit.
From the top, the views on a clear day extend to the South Downs and, on exceptional days, to the English Channel. The descent options are varied: north towards Abinger Hammer and Friday Street, or west towards Holmbury St Mary. Each offers a thrilling downhill on quiet lanes, though loose gravel can be a hazard after rain.
Planning Your Ride
The full challenge route starts from Dorking and heads south-west through Wotton before tackling the main climb via Leith Hill Lane. After the summit, descend to Abinger Hammer and pick up the A25 back to Dorking, or extend to Holmbury Hill for additional climbing. The total route covers approximately 35 kilometres with significant elevation gain.
There is limited parking near Leith Hill itself, so starting from Dorking is advisable. The Stepping Stones pub at the foot of Box Hill and the Abinger Hatch at Abinger Common are good refreshment stops. This route is best attempted in dry conditions, as the steep lanes can be treacherous when wet. It combines well with the Box Hill Olympic Loop for a full day of Surrey’s finest climbs.
