Langdon Beach and Tunnels

Highlight • Historical Site

Langdon Beach is a bit hidden, you can descend to the beach via a small path and a ladder about 5m high. The tunnels, the defense positions and the shipwrecks that can be seen at low tide are interesting. The descent is worth it.

Guided tours by volunteers at the National Trust through these WWII tunnels/bunker. 125 steps down, approx 90 minute tour, only £6. Very factual, learn about the troops who used it, the reason it’s there, and how it was built.

£6 for an hour’s tour by the National Trust. Well worth it! Go 125 steps underground and tour the tunnels from WWII

impressive descent to the Longdon Bay Tunnel with access to the pebble beach. Great little picnic area (unfortunately a bit littered) with a long ladder down steeply to a pebble beach. Please pay attention to the tides, as the beach may not be accessible at high tide as the ladder is in the water. Furthermore, swimming shoes are recommended because of the pebbles. A wonderful place

The complex belongs to the National Trust and with a membership card you get free entry into the World War II tunnels that were driven into the cliffs.
