CLAM - Silfra & Thingvellir
Forget everything you think you know about diving in Iceland. CLAM isn't Silfra’s crystal clarity; this is a proper wreck dive, and it’s a big one. The tanker, sunk back in 1950, stretches out at 134 metres, offering plenty of structure to explore. We’ve found the stern section particularly interesting, with some of the plating collapsing inwards, creating cool swim-throughs if you're comfortable with overhead environments. The currents here can be a bit frisky, so check the conditions before you go, but the rewards are worth it, with decent visibility on good days revealing the scale of this maritime relic.
