    Is it safe to swim in bioluminescent bay?

    While there are only a few bioluminescent bays in the world, not all of them allow you to swim in them. You are allowed to swim in Biolumious Bay in Grand Cayman and Puerto Rico.

    Refer to your tour operator for safety in whatever area you’re choosing to swim in. And, if you’re scared of swimming with stingrays or sharks, this is a much chiller option! But if you’re into thrills, the Bahamas is a great option for your next diving adventure.

    What do you wear on Bioluminescent Bay tour?

    • bathing suit
    • cover up
    • rash guard
    • light jacket
    • reef-safe sunscreen

    When taking a Bioluminescent Bay tour, you should wear a light jacket, as the boat can get chilly when the sun is down. Your bathing suit and a cover up because the views are better when you jump in the water.

    And, plenty of reef-safe sunscreen if you’ll be outdoors before the sun goes down. You might also want to bring along some water shoes if you plan on jumping in the water, but that’s not entirely necessary since you’ll be swimming most of the time.

    What time of year is best for bioluminescent bay in Grand Cayman?

    Grand Cayman bioluminescence bay is visible all year long. However, it’s best when there’s a new moon, meaning there’s little to no light in the night sky so the plankton can shine brightly!
