One of the few saving graces of former phosphate mines is that they provide awesome air for mountain bikers in Florida.
Alafia River State Park is one of the rare places where you can launch on a Florida downhill. Once strip-mined, the terrain is largely reforested.
Drops and climbs are part of the fun on this park’s trailsA tremendously twisty series of mountain bike trails attract riders from around the state and beyond, but hikers and equestrians can put in quiet miles well away from the bike crowd.
The park’s campground provides a quiet respite east of the Tampa metro, not far from the South Prong of the Alafia River.

About the Park
Over 42 miles of trails thread across this landscape above the Alafia River basin, with a world-class International Mountain Bike Association trail system a huge draw on weekends.
The radical terrain of reclaimed phosphate mines provided a backdrop for steep drops and curves for 22 miles of technical, challenging trails built and maintained by local bike enthusiasts.

You can ride on your own, join a guided ride with SWAMP, or go on an Adventure Race, but Alafia River is not a one-note park, despite a bike shop on site providing rentals and repair services.
The Old Agrico Trail, Lonesome Lake Trail, and South Prong Trail tempt hikers with deep shade and rugged terrain. Double-track and equestrian trails are also shared with hikers.
Starting from a separate entrance off CR 39, the perimeter of the North Trail System has been blazed red to make it easier to follow, since navigation is otherwise between numbered markers.
Old Agrico Trail Short but challenging, the Old Agrico Trail isn't like any other hike you'll find in Florida. Steep slopes, drastic drops, and dead-ends make for adventure!
Alafia River North Trails Once the site of a large phosphate mining operation, the North Trails at Alafia River State Park offer an easy, quiet hike across slightly undulating terrain. Follow our suggested routes or strike out on your own with a trail map and GPS to find connections to neighboring natural lands.
Paddlers have access to the South Prong of the Alafia River from a separate entrance, navigable from the main part of the park upstream.
