A one-hour hike north of Kelham Beach will get you to Sculptured
Beach with its 9 arches. At the south end of the beach is a rock wall
out into the ocean toward Thumb Rock. There is an arch (Thumb Rock
Arch) which can be climbed through to get to adjoining Secret Beach.
The big attraction there is the tunnel which opens into a large (40ft.
across, 50ft. deep) sinkhole in the side of the cliff. The catch is that it
takes a negative 0.1ft. tide to access the beaches. Find some tide tables.
