Don’t let your day end when the sun goes down.

Enjoy a relaxing kayak tour at sunset that leads to the fascinating Laguna Grande in the town of Fajardo located on the Northeast corner of the island. Under a blanket of the night sky and the historical lighthouse, you can touch the waters that glow with bioluminescent organisms.

The activity starts at sunset in the small fishing village of Las Croabas where you meet the friendly guides. Check-in and get equipped with all the gear, including botanical-based insect repellent. Get the Kayak 101 Safety training, then board your kayak.

Paddle across a small fisherman’s harbor to the entrance of Las Cabezas de San Juan Reserve. Here, you enter a mystical channel that leads to a peaceful place where the mangroves create natural tunnels and the sights and sounds of wildlife surround you. After a 25- to 30-minute paddle through the channel, based on traffic and tidal currents, your guide stops once in the lagoon to give commentary on the following points of interest:

• Mangrove forest and the different species
• Birdlife that inhabits the area
• Aquatic marine life that uses the lagoon as an estuary
• Information on the bioluminescence organism
• History of the lighthouse
• Insight on seven of eight ecosystems found in the area

Afterward, enter the lagoon called Laguna Grande (large Lagoon), where you paddle along the edge of the mangrove forest and watch the stroke of each paddle light up a bioluminescent blue-green/white-green.

Encounter fish that look like shooting stars as they swim through the thick concentration of Pyrodinium Bahamense, a species of Dinoflagellate. At the breakpoint, admire beautiful views of the rainforest and the lighthouse of Fajardo, accompanied by good conversation.

Next, begin the route to Bird Island to view the many birds that roost there overnight. Once quietly rounding the small island, start the return to the departure site. This tour is offered under the full moon cycle, so checking what the moon phase is recommended.
