Frequently asked questions
Find clear, factual answers to plan your boat tour and swim in Falmouth.
What makes the Luminous Lagoon in Jamaica glow?
Microscopic organisms called dinoflagellates produce the bright blue-green glow. They thrive in this specific spot because the mixing of the Martha Brae River and the Caribbean Sea creates a perfect brackish environment.
How deep is the water in the Luminous Lagoon?
The water depth in the designated swimming area is shallow. It generally ranges from 5 to 8 feet deep.
Is it safe to swim in the Luminous Lagoon?
Yes, visitors are permitted to swim for 15 to 20 minutes during the tour. Life jackets are provided. You must follow the captain's instructions on when to enter the water. Read our Kids and Families guide for family safety tips.
When is the best time of month to visit the Luminous Lagoon?
The best time to visit is during the new moon phase. Dark, moonless nights with clear weather provide the best contrast to see the bioluminescence brightly.
How long does the Luminous Lagoon boat tour last?
The standard guided boat ride lasts roughly 35 to 45 minutes. This includes 15 to 20 minutes designated for swimming.
Can you take pictures of the bioluminescence?
Yes, but flash photography is strictly prohibited on the boat tour. The bright flashes ruin the visibility of the glow and disturb other guests. You need a camera with excellent low-light capabilities.
What should I wear on the Luminous Lagoon tour?
Wear a swimsuit under your clothes and bring water shoes. The air can get chilly on the ride back, so pack a light jacket. Do not apply heavy lotions or bug sprays before swimming.
Does the Luminous Lagoon glow when it is raining?
Heavy rain can disturb the surface of the water, causing it to glow automatically. However, severe weather can result in tour cancellations. Clear weather is generally best for the excursion.
What is the difference between Luminous Lagoon and Glistening Waters?
The Luminous Lagoon is the natural bay where the bioluminescence occurs. Glistening Waters is the local marina, restaurant, and hotel where the tours operate from.
How much does the Luminous Lagoon tour cost?
Standard tickets at the marina are $25 for adults and $12.50 for children under 10. Third-party packages with hotel transfers cost $60 to $120. Check our Tickets page to compare options.
