Overview
The Luminous One is a boat ride to the original bioluminescent bay in La Parguera, where guests are able to swim in the bioluminescence. The total tour time is about an hour. Guests are allowed to swim for 20 minutes to preserve the organism and habitat.
La Parguera is a quaint fisherman's village with restaurants, bars, and souvenir shops. We recommend getting to the village early to find parking, relax, and enjoy La Parguera before the trip!

When is the best time to see the bio bay?
The glow is visible year-round, but to see it at it’s brightest we recommend going during a cloudy or moonless night.
How long does a bio bay tour take?
Time on the water is usually 1 to 2 hours. Add 45 minutes for check-in and the safety briefing, and add travel time from wherever you're staying. Budget most of an evening.
Will I definitely see the glow?
The bays glow year-round, but brightness varies with moon phase, recent rainfall, and water temperature. Operators don't guarantee a specific intensity. Booking near a new moon is the best thing you can do to stack the odds.
What's the cancellation policy?
Cancellation policies vary depending on the provider, but most will give a full refund with 24-48 hours notice.
Kayak or boat tour, which is better?
Kayak, for most people. You're closer to the water and the glow is more vivid around a paddle than around a hull. Choose the boat tour at La Parguera if you want to swim, or if paddling isn't practical for your group.
