In the waterHolbox Bioluminescence Snorkeling
Holbox bioluminescence snorkeling is a 1.5-hour night swim in mask and wetsuit in shallow water that glows as you move; it costs about $58 and is best June to October on moonless nights.
Book the 1.5-hour night swim with mask and wetsuit for about $58; it isn't reef snorkeling, it's a swim in glowing plankton, best on moonless nights from June to October.
- One night tour includes mask and wetsuit; the popular kayak tour doesn't put you in the water.
- Starts at 8 pm and lasts about 1.5 hours.
- The glow is strongest June–October and weakest under a full moon.
- Not for children under 5 or people with heart problems.

What Holbox Bioluminescence Snorkeling Is
Tiny plankton flash blue when the water moves — you make the light by swimming.
Microscopic organisms, mostly dinoflagellates, that glow when disturbed by a hand, a fin or a paddle.
Shallow water at night: you see the glow around you, not fish.
Mask and wetsuit are provided and fitted before you go in.
