The Rainforest & Bio Bay Tour is simply a must! Experience Puerto Rico’s two greatest natural attractions starting with a scenic drive and a stop at a local fruit stand. After an interpretive hike on natural trails lined with beautiful flora and fauna, as well as some river wading and rock scaling, we will arrive at a hidden gem in the heart of the majestic El Yunque National Rainforest. In this breathtaking segment of the forest, you can swim in natural pools, refresh under waterfalls, slide down exhilarating waterslides, swing from ropes into the river, jump from different rock formations, and simply relax to the sounds of cascading waters while soaking in the beauty of this very special place. Enjoy dinner and a break at a local restaurant before the Bio Bay tour.
4hAfter receiving a few kayaking tips, we will kayak approximately 30 minutes through the Red Mangrove Forest to reach the Bioluminescent Lagoon. Along the way, your Eco Guides will point out the forest's beautiful protected flora and fauna. Upon arrival at Laguna Grande, the sun will set, and the magic will begin. With every stroke of your paddle, sparkles will appear in the water. The kayaks will create a swirl of light, and the fish will glow in the darkness of the water.
2hGet ready to experience two of Puerto Rico’s most amazing natural attractions in one unforgettable day! This full-day package covers the best of the East Coast, so you don’t have to worry about planning a thing. We’ve got you covered with round-trip transportation, a guided rainforest adventure tour, and an evening Bio Bay kayak tour.
Discover the hidden gems of El Yunque with our "off the beaten path" rainforest adventure. Our expert guides will lead you through muddy trails, across rivers, and to stunning waterfalls. Enjoy natural waterslides, a thrilling rope swing, and immerse yourself in the raw beauty of Puerto Rico’s premier tropical rainforest. It’s a journey filled with excitement and natural wonders you won't find anywhere else.
As night falls, prepare to be amazed by the bioluminescent waters of Fajardo Bio Bay. This natural wonder glows thanks to tiny organisms called dinoflagellates. Paddling through these sparkling waters is a magical experience you’ll never forget.
