Never thought of Iceland as a snorkeling (or SCUBA) destination? Well think again.
It might take a dry suit (warmer than a wetsuit) and a couple of layers, but it's well worth the effort. Snorkeling here allows you to float between the North Atlantic and European tectonic plates - and rewards you with majestic compilations of black lava rock, shocking green grasses, muted tan rippling sand, and brilliant blue water. It's honestly on a par with just about any Caribbean diving I've ever done.
Aside from the stunning beauty and seeing an exotic destination from a completely new angle, snorkeling Iceland provides you with one hell of a cocktail party story for the rest of your life.
