Fajardo bio bay tours
Discover the glowing waters of Laguna Grande, the easiest bio bay to access from San Juan

Join us on an exhilarating one-hour or two-hour ATV ride through the foothills of El Yunque National Forest! This invigorating ride exposes you to the spectacular scenery of Puerto Rico’s east coast as you roam through towering trees, tread through creeks, climb hills, and coast through vast rugged rainforest terrain on our 600cc ATVs!
Upon arrival, you are given a 10-minute introduction on how to operate the vehicle, including safety instructions. Then the real adventure begins as you ride through the rainforest, splash through the river, and more. Whether you are an experienced rider or a first-timer, you’re sure to have an exhilarating trip.
You also have the unique opportunity of stopping at Mameyes River, which comes directly from the rainforest, for a refreshing swim in its pure, clean, crystal-clear waters.
