Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Crown Hill Bay offers some of Cornwall & Devon's richest reef diving. Water ranges 10-18°C, warmest July, August, September.
Crown Hill Bay is a nice, easy entry for a calm day. We’re talking shallow stuff here, maxing out at six metres, so it’s perfect for knocking out those beginner skills or just enjoying a really relaxed bimble. You'll find yourself drifting over some surprisingly healthy soft corals for this part of the world, tucked in amongst the kelp forests. Keep an eye out for blennies peeking from the rocks and some of the smaller wrasse darting around. It’s a gentle introduction to UK diving, ideal if you want to avoid anything too challenging or just fancy a chilled-out explore.
