Jökulsárlón, Iceland It’s unlikely you would want to sunbathe here (although at times it is drenched in 24 hour sunlight) as it’s not particularly warm. Jökulsárlón is a glacial lake in Iceland, and the beach on the outskirts is made of black sand. One of the most striking things about this beach is the pieces of glacier that have broken off and lay strewn across the beach. They look like big clear crystals. It’s very atmospheric.
