St Boniface Down

St Boniface Down

St Boniface Down rises above Ventnor and is the Isle of Wight’s highest hill. DoBIH records 242 m and a 242 m drop, making it a Marilyn. The exact natural high point at SZ 56881 78520 is unmarked ground inside the outer security fence. The nearby higher embankment is artificial and ground by the car park farther east is slightly lower. A walk on the public perimeter paths does not reach the recorded summit: do not climb fences or enter the compound without permission.

A complete public-path circuit

The National Trust’s Views of Ventnor trail starts and finishes at Ventnor Downs car park, SZ565784, off Down Lane. Its full circuit is 4 km with 200 m ascent and a published duration of 1 hour 15 minutes to 1 hour 45 minutes.

Follow the outside of the radar perimeter, then descend the steep stepped ridge towards Coombe Bottom and the old station area. The route uses the Mitchell Avenue pavement, climbs through woodland, crosses the lower slopes of St Boniface Down and makes a very steep ascent back to the downs. Its final section follows the V113 and V43 connections and the grassy track beside the road back to the original car park. Use the Trust’s detailed route and a map. The totals cover this full loop, not a start in Ventnor town or a diversion to another hill.

Despite the short distance, the route is challenging, with more than 100 steps, steep grass slopes and gates. It remains outside the security compound and does not promise exact-summit access.

Landscape and history

The down is part of the island’s Cretaceous chalk landscape. Open grassland supports butterflies, while holm oak woodland has spread across southern slopes. Feral goats help manage scrub. Views from public paths include Ventnor, the Channel and, from some sections, Sandown Bay.

The name commemorates St Boniface; his preaching at nearby Pulpit Rock is a local tradition. The Trust advises against seeking the well named for him because its steep, overgrown site is difficult to reach.

The former RAF Ventnor station contributed to the Battle of Britain and the D-Day operations. Historic England distinguishes the 1937 choice of site from construction in 1938–39. The surviving radar structures and defences are protected historic features; this does not open the compound to visitors.

Getting there and staying safe

Use the National Trust parking off Down Lane before the radar fence. Down Lane is steep and single-track. Southern Vectis service 3 serves Upper Ventnor on the Newport–Ryde route. Check current stops and return times and add the walking approach to the circuit’s figures. On 18 October 2026, the operator listed a temporary closure of the Chimney Steps stop towards Newport, using Bonchurch Shute instead; that stop is separate from the Upper Ventnor approach.

Toilets, cafés and shops are in Ventnor. Carry water, dress for wind or cloud, and expect mud and slippery steps in wet weather. Keep dogs on leads around livestock and wildlife, obey seasonal bird signs and close the goat gates. Appuldurcombe Down and the Isle of Wight’s St Catherine’s Hill are separate hills requiring their own route planning.
