Join a day trip to El Yunque Rainforest and the bay of Laguna Grande, two of Puerto Rico's natural gems, on a day trip from San Juan. Follow your guide through nature trails, kayak in Fajardo Bio Bay, and observe bioluminescence at night. Enjoy return hotel transfers, snacks, and all entrance fees.

Following a morning pickup at your accommodation, embark in direction of your bio bay and rainforest adventure. Enjoy the beautiful views along the scenic route through the north side of the island and learn some facts about the areas from your guide. Make a stop in the town of Luquillo and enjoy some fresh local fruits before continuing the journey to Puerto Rico's majestic rainforest. El Yunque is the only tropical rainforest, and the most studied forest in the United States National Forest System. Admire its biological diversity with its plants and animals – some of which are found only in Puerto Rico. Hike through trails lined with beautiful flora and fauna, and some river wading.

Arrive at a hidden gem located in the heart of the rainforest. Enjoy the breathtaking segment of the 29,000-acre forest and swim in natural pools and waterfalls, slide down a waterslide, rope swing into the river, jump from different rock formations, and enjoy fresh local fruit with a view.

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 (at your expense). Relax a bit 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. Tiny organisms called dinoflagellates make the water glow at night. Watch how sparkles appear in the water at every stroke of your paddle, follow the swirl of lights created by the kayaks, and admire the glowing fish in the darkness of the water.
