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.

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
