The tour takes you onto a shallow lagoon after dark where the water glows electric blue-green every time the boat moves or you trail your hand in it. The effect comes from microscopic organisms that light up when disturbed. Expect a 30-45 minute boat ride with a basic narration, plus time to swim if you want. The glow is genuinely striking in darker conditions, though it varies by moon phase and water disturbance. It's not a party boat; most trips feel calm and a bit magical once you're out on the water away from lights.
Go December through April for drier weather and slightly better odds of clear skies. Avoid heavy rain periods if possible. Expect to pay around $55-110 per adult depending on whether you choose a simple group tour with transport or a private option. Kids usually cost less. Book something that includes round-trip transport from Montego Bay hotels; it's worth it.
Tip: Choose the smaller evening tour that includes a swim stop over the crowded sunset ones. Skip the overpriced photos sold on the boat; your phone with night mode works surprisingly well. Bring a towel, reef-safe bug spray, and go on a new-moon night for the strongest glow.
