13 tours · €53–€797 per person · ★ 4.7
The bioluminescent bay in Puerto Rico is really three bays, and the 13 bio bay tours here were picked by hand from every listing rated 4.5★ or higher. Prices run from €53 per person for a clear kayak on Vieques to €797 for a private boat day that ends with a swim in the glow. Most people book the bio bay kayak tour in Fajardo: a tandem paddle through the mangrove channel into Laguna Grande, two hours all told, with snacks and life jackets in the price. The Vieques bio bay tour needs a ferry or flight booked weeks ahead, and La Parguera on the south coast is the only bay where boats go out and swimming is allowed.
A quick way to choose: check the moon, because a full moon and a cloudy sky dim the glow and the kayak operators cannot refund the weather. The Fajardo tours weigh guests at check-in, take children from six and rarely include transport from San Juan; the combo days with El Yunque do.
