El Yunque is the only tropical rainforest and the most studied forest in the United States National Forest System.

After working up an appetite with an exciting first half of the day, make a stop for dinner at a local restaurant and savor Puerto Rican cuisine (cost not included). Relax until it’s time for the second part of your combo tour – the Bioluminescent Lagoon, one of planet earth's best-kept secrets. Begin your Fajardo Bio Bay kayak tour at Las Croabas. After receiving a safety briefing on kayaking, head toward the Red Mangrove Forest with an amazing view of the sunset. Enjoy kayaking for approximately 30 minutes, and admire the forest's beautiful protected flora and fauna. Upon arrival in Laguna Grande, let the magic unfold.
