Itinerary

El Yunque National Forest
Get adventurous, get muddy and get off the paved trail! Hike to explore different zones of the rain forest and enjoy beautiful views, natural pools and the Atlantic Ocean. Once we arrive to the skirts of El Yunque we will start with a 25-30 minute journey on a river-wading and rock scaling path to the river. You will see bamboo trees, flowers, and beautiful plants and experience rivers, waterfalls, and natural trails. We will make a stop to visit a collecting pool that forms at the base of a small waterfall. Here you will have the opportunity to swim in its crystal clear waters, swing from a rope and enjoy the different tones of its deep pools.
Then, after a few minutes of hiking and rock climbing to the upper sections (more strenuous), arrive at a natural river where you can swim, cliff jump, enjoy the natural water slides and small waterfalls.
After the hike, we will stop for lunch at a local restaurant (food cost not included) for about an hour to an hour and half.

Laguna Grande
We will then proceed heading East to join on the guided nighttime bioluminescent bay kayak tour. Experience the mystical mangrove channels leading to Laguna Grande. Look into the water to see the glowing pyrodinium bahamense, microscopic planktons capable of producing natural light at the touch of your hand or paddle (like fireflies). Admire these amazing organisms up close as you paddle on a 2-person kayak through the mangroves for an estimate of 30-minutes, and learn from your eco-tour guide about this fragile and unique ecosystem. Once reached the lagoon, you will have some time to play with the water (from within the kayak) and receive more information, before we head back to the mangrove channels for another kayaking journey of approximately 30 minutes .
Enjoy provided snacks at the end of the kayak tour, before returning to San Juan.
Please note: The bio bay is an unpredictable natural phenomenon that may be influenced by multiple factors. Bioluminoscity level can vary from very visible to minimum or none without any previous notice. Full Moon phase may also affect the visibility of the bioluminescence. In the event of this happening alternate methods such as the use of a tarp will be incorporated in order to appreciate it.
