Dive-site story
Set along Dorset's Jurassic Coast, Durdle Door centers on a natural limestone arch. Below the surface, chalk and limestone reefs yield to kelp forests, coarse sand, and shingle. Gullies and ledges parallel the coastline, sheltering regional marine life. Shore entries demand a steep descent down the cliff path with gear; boat access from adjacent ports avoids the climb.
Submerged limestone ridges and kelp-covered boulders
Summer cuttlefish and spider crab sightings
Sheltered shallow gullies populated by blennies and juvenile reef fish
