With its warm, tropical climate, chances are excellent you’ll be spending a lot of time outside — even if you don’t decide to go rafting down the Martha Brae river. There are plenty of beautiful beaches to choose from — but if you’d rather be under the water exploring, there’s plenty of snorkeling and scuba diving to keep you busy, including in the famous Blue Lagoon.
For a truly unique experience, be sure to visit the Luminous Lagoon — microscopic organisms in the water make it appear to be glowing. You can even swim in the water and see the beautiful, natural glow firsthand if you like.
