Ever wished you could swim in the stars? In Thailand, you can! This nighttime treat of a tour will take you out to snorkel and swim in the magical bioluminescent plankton, which makes the sea glow bright blue. It feels and looks a lot like swimming through the galaxy. After a handy pick-up service from your hotel in Krabi Town, Klong Muang Beach, Tubkaek Beach or Ao Nang Beach, you'll board a traditional longtail boat and start your incredibly atmospheric evening. Watch the sunset over a BBQ dinner at Railay Bay or the famous Phra Nang Cave Beach, then strap on the flippers for some snorkeling fun. It's the Andaman Sea, but you would be forgiven for thinking you're floating around space. A magical must-see from Krabi.
