Overview

This two-hour kayak tour in Fajardo takes place in tandem kayaks on the Bio Bay, also known as Laguna Grande. A professional marine biologist guides the tour, explaining the scientific conditions behind the bioluminescent phenomenon and the ecological balance of the bay. Guests receive all necessary gear, snacks, and basic kayak instruction. Participants must weigh 240 lbs or less, as guests will be weighed onsite to meet this limit. Children younger than 6 years are not allowed, and the minimum age to join is 6. Pregnant women and people with certain medical conditions are not permitted to participate. The tour runs at sunset or early evening to best observe the glowing waters, with the option of a tarp to block light pollution. The environment is natural and dark, so first-time kayakers or those uncomfortable in the dark are advised to take an earlier trip. Bathrooms are available on site but may be in poor condition. Guests should come prepared to get wet and bring a change of clothes. The tour continues rain or shine, and due to popularity, the canal may be crowded with other kayaks.
