This is a great place to spend a free day in Puerto Rico! There are many interpretative trails in this park, and all are free and open to the public. Some lead to caves, others lead to beautiful views. Take your pick!
There are also many covered areas for picnics. This would be a great way to explore something besides the beaches and nightlife of Puerto Rico and is perfect for the whole family.
The trails are mostly leveled off and easy hikes, although some can be a bit more challenging. Be sure to bring lots of water, as it can be humid. Also, bug spray will be your friend! If you plan to take a trail that leads to a cave, be sure to have a flashlight with you as well!
