Grand Cayman · BIOLUMINESCENT BAY TOURS
The bay glows only on dark nights, which is why every operator here sells by lunar date rather than by day of the week. These 12 tours split between kayak and boat, and between swimming in it and watching from the deck. Prices and moon-window notes below.

“Travelled with family on 23rd dec night. There was no such bioluminescence in the bay. It was all funny to spend this much money for literally nothing. Crew & staff was very nice but the timings were told to be 6:30pm to 9:30pm. But we were back by 8:00pm lol. Felt like little scammed with this activity specifically”

“These thieves agreed to pick us up at our Condo which Viator CONFIRMED! They did not pick us up. Instead they stole over $300, and refused to refund. That has cost Viator our future business, and likely legal action. DO NOT USE THIS PROVIDER. Viator should cancel relationships with them.”
