Bioluminescence Snorkeling Holbox — What the Tour Is

Bioluminescence snorkeling in Holbox is a guided night swim, not a reef snorkel. You put on a long wetsuit, special water shoes and a snorkel mask, get into shallow water after dark, and every movement of your hands and feet lights up the water around you. The light comes from plankton, and it is the only thing you are there to see.

Holbox Bioluminescence Experience is the one listing on GetYourGuide that puts you in the water. It lasts 1.5 hours, started at 8:00 PM on the date we checked, and includes private transportation within Holbox, the gear and a SECTUR-certified guide. It is rated 4.7 by 7 travellers and costs from $66 per person. Children from 5 can join; the listing names people with heart problems and wheelchair users among those it is not suitable for.

It is a gentle outing rather than a swim workout, in shallow water. One reviewer wrote that they "learned even more about plankton and star constellations in the process"; another, who went with two families, called it a late night but worth it.

Holbox Bioluminescence Kayak vs Swim

Holbox has two ways to see the glow. The swim puts you in the water in a wetsuit for 1.5 hours; the kayak tour, Holbox: Bioluminescence Kayaking and Stargazing, keeps you in a kayak for 2 hours and adds stargazing, from $51, rated 4.6 by 350 travellers. The kayak is the one to pick if you would rather stay dry or are travelling with small children.

Best Time for Bioluminescence in Holbox

The best time for bioluminescence in Holbox is a moonless, rain-free night. The light comes from plankton that glow when the water moves, and it is faint: a bright moon washes it out and rain clouds the shallows. Both tours run all year, so for the glow the moon matters more than the month.

The swim happens in the shallows off the island, not on a reef; local guides point to the Punta Cocos and Punta Mosquito side. There is no boat ride, and the tour picks you up and brings you back within Holbox. On the date we checked it started at 8:00 PM and the kayak tour at 9:30 PM, so either fits after a day on the water.

Neither listing promises how strong the glow will be on a given night. Check the moon phase before you book, and if your dates allow, choose a night close to the new moon.

Our group was two families, including a 10-year-old and teenagers and grownups and kids both enjoyed the experience. It was a late night but definitely worth it!

No. Neither listing promises how strong the glow will be. It is best on moonless, rain-free nights and hard to see under a bright moon, so check the moon phase and pick a night near the new moon if your dates allow.

Best time for the glow →

From 5 for the night swim, which lists children under 5 as not suitable; the kayak listing does not state a minimum age. A reviewer who went with two families, including a 10-year-old and teenagers, wrote that grownups and kids both enjoyed it, and that it was a late night.

Swim or kayak →

A long wetsuit, special water shoes and a snorkel mask, all included, plus a mosquito mask for the shore. Wear a swimsuit underneath and bring a towel and dry clothes; food and drinks are not included.

What the tour is →

No. It is a swim in shallow water near the island, where the plankton glow; you won't see coral or reef fish. For reef snorkeling, the Cabo Catoche tours go 40–45 minutes by boat in the morning.

The reef trips →

1.5 hours in the water, plus pickup and drop-off within Holbox. It started at 8:00 PM on the date we checked, so you are back in town well before midnight. The kayak tour is 2 hours and started at 9:30 PM.

Swim or kayak →

You should be comfortable in shallow water. The swim happens in the shallows off the island in a long wetsuit, not in deep water.
