The best way to experience this rain forest is to rent a car and drive yourself to the top of road #191, north side. Trails are marked and well maintained towards the top. Forest Service tours are offered until 2:30 on the half hour for a $5 donation. Private Guides may offer transportation as well. At the top of south road # 191 there are excellent pools to swim in the wonderful clear water. No real trails but walking on the road beyond the road barrier is a great way to see the forest.
These little sandy keys with turquoise waters, white sand beaches and coral reefs lie east of Fajardo and can be visited by boat only. Icacos is the best place to be dropped off for the day by water taxi because it is the largest, offers a little shade and more to explore. No facilities on any of these islands. Lobos has the best reefs and schools of Blue Tang you can feed. Palominitos is so beautiful in the afternoon but tiny and offers no shade.
Biobays may be visited by kayak or electric boats. Vieques Island and Fajardo both offer these trips
There are many small Inns and lodges surrounding El Yunque rainforest on the north, east and south sides.
Vieques Island is about 7 miles ( as the crow flies) east of Puerto Rico and can be reached by ferry or airflight. The worlds brightest biobay may be the one in Vieques.
