There are over 24 miles of hiking trails in the forest. These trails are for hiking only. The park forbids the use of Motorcycles, bikes, and horses. The most popular trail is the La Mina Falls trail. the trail is about three quarters of a mile long and ends at a beautiful waterfall where hikers can swim in the water.
