Explore areas of Fort Nelson not usually open to the public.

Venture into the Fort’s hidden depths and visit the East Tunnel on this special guided tour.

Normally closed to the public, it is one of the last unrestored areas within the walls, where original features remain untouched. This unique opportunity offers a rare glimpse into a lesser-seen side of Fort Nelson.

The tour involves changes in surfaces, low light levels, walking through the tunnel and the requirement to follow pathways. The East tunnel is not fully restored, and lighting is provided by torches and portable units. The tunnel pathway is narrower than that of the main tunnel.

Fort Nelson is a scheduled ancient monument and contains areas of uneven ground.
