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.
