About Castells
Castells is a boat dive on a rocky bar off the Barcelona/Maresme coast, with sand on both sides and a deep sea-side line. Much of the route sits in deeper water, so it is best treated as an advanced, nitrox-friendly profile rather than a shallow scenic swim. Bring a torch for the rock work, and plan it for settled water and disciplined gas management.
