Please note: We are not currently running Tunnel Tours as the space is too small to be Covid-compliant. Check back to this page for updates on when they can start again.
The Southsea Castle Tunnels have been re-opened for short guided walks, allowing you to explore much further into the fortification. These free tours will take place on Wednesdays and Sundays at 11am and 11.15am.
Places on each walk are limited to 20 so please book ahead by speaking to a member of staff in the Waterfront Gifts shop. Alternatively, call 023 9284 1625 to book your place. Please phone ahead for further information, or to check tours are running on the day you intend to visit.
The tunnels are often wet and slippery, so appropriate clothing and footwear is essential.
