The Luminous Lagoon is a natural bioluminescent bay located in Falmouth, Jamaica. Millions of microscopic organisms emit a bright blue-green glow when you disturb the water.
The lagoon forms where the Martha Brae River empties into the Caribbean Sea. The mixture of salt and fresh water creates an ideal brackish environment for dinoflagellates. Nightly boat tours take visitors out onto the bay to see the glowing water firsthand.
Standard entry tickets start from $25 for adults and $12.50 for children under 10. Tours last 35 to 45 minutes and include a designated swimming stop.
45 minsGuided ride
Guided boat rides last 35 to 45 minutes and leave nightly after sunset. The captain explains the science and history behind the bioluminescence as you ride into the dark lagoon. Sit near the back of the boat for the best view. The engine heavily churns the water, creating a bright glowing wake.
15-20 mins5-8 feet deep
The boat stops in a shallow section of the bay that is 5 to 8 feet deep. You can jump in and swim for 15 to 20 minutes. The water illuminates brightly around your body as you move. The bottom consists of squishy, jelly-like mud, so wear water shoes.
No flash allowedWatch for fish
The organisms concentrate heavily along the dark borders of the bay near the mangroves. Fish constantly dart through these areas, leaving neon glowing trails in the dark water. Watch the surface closely to spot streaks of light caused by schools of fish.
