Climbing Walls and Bouldering in Portsmouth

Ravelin Sports Centre

The University of Portsmouth's Ravelin Sports Centre on Cambridge Road opened in September 2022, and its climbing wall rises through the middle of the building. There are eight auto-belays on a wall up to 10.85 metres high, carrying three routes each from 3+ to 7c, and about 120 m² of bouldering up to 4 metres. Climbing is booked in 90-minute sessions through the UOP Sport app, each supervised by an instructor, and it is open to the local community as well as students. New climbers book a 30-minute induction first. The minimum age is 7, and under-18s climb with an inducted adult.

Bouldering under a fort

Fort Purbrook Bouldering is in the Cellars of a Victorian fort on Portsdown Hill, reached through its underground tunnels and run by Peter Ashley Activity Centres. The Boulder Room, first built by Bendcrete in 1992, has 45-degree panels, waves, slabs, cracks and an eight-foot roof; the Training Room has a five-sided tower, a curved wall and a chimney. Together they offer about 1,400 sq ft. Public sessions run on weekdays and weekend mornings, but group bookings can take the rooms, so phone ahead or check the centre's Facebook page.

Red Spider in Fareham

Between Portsmouth and Southampton, Red Spider at Fort Wallington is part of the Spider Climbing group and spreads over 200 boulder problems, graded VB to V8+, across two floors. One of eight sections is reset each Thursday, and the competition wall is reset every month. There is a training area with a digital board, a café and free parking, and younger children can play in the Kids Castle and Pirate Ship. A Multi-site add-on lets members climb at the other Spider walls in Guildford, Surbiton and Sutton.

Prices

In October 2026 a supervised 90-minute session at Ravelin cost £11.50 (free with an Ultimate membership, £54.99 a month, which also covers the gym and pool), plus an £8 induction on your first visit. Fort Purbrook charged £9 for adults and £40 a month, and Red Spider £14 peak and £11 off-peak, or £57 a month. Red Spider adds a one-off £2.50 registration fee.

Roped climbing and the Solent

Portsmouth has no lead wall open for drop-in climbing. Climb Hayling, a 7-metre roped wall at Hayling College, is used for children's clubs, parties and group bookings rather than public sessions. For lead and top-rope climbing, most local climbers go to Parthian Climbing Southampton or the hangar wall at Calshot; see our Southampton page. On the Isle of Wight, Sandown Rocks has a floodlit 12-metre outdoor wall, climbed in booked instructor-led sessions.

Children

Ravelin runs NICAS-accredited lessons for 7 to 17-year-olds, Fort Purbrook has a junior bouldering club for 8 to 12-year-olds in term-time blocks, and Red Spider has NICAS termly clubs, home-education clubs and parties. Under-18s must be supervised by a registered adult at all three.

Climbing outdoors

There's no climbable rock around the Solent. The nearest big outdoor area is Portland in Dorset, with sport routes on limestone sea cliffs and quarries, deep-water solos and bouldering, all covered by the Climbers' Club guide.
