East of Tampa and Brandon, the 6,000 acre Alafia River State Park has 20 miles of multi-use trails designed with mountain biking in mind. As the property was all once phosphate mines and has since been reclaimed it offers terrain not usually seen in Florida. The trails run through swamplands and dense hammock forest. The sheer elevations of the narrow bike trails are very exhilarating and similar to bike trails in North Carolina.
To reach the trailhead from US75, use Exit 51 (SR60). Head east on SR 60 through Brandon for 12 miles to CR39. Head south on CR39 for 13 miles to the park entrance on the left.
There are three major loops - BLACK LOOP is very technical with steep drops and strenuous climbs and is for the advanced rider. BLUE LOOP, Requires the skills of an intermediate rider on short sections. GREEN LOOP, the easiest of the trails, but still challenging, for experienced beginners. Helmets are required on the trails. Trails are indicated by markers with colored symbols on them. There are two sublevels of the BLACK LOOPS identified by a differing number of black diamonds; one diamond is an advanced trail, if you see two diamonds it is an expert level trail. The trails at Alafia River State Park were constructed and are maintained by volunteers from the Southwest Association of Mountain Bike Peddlers (SWAMP).
For more riding, the Boyette Park is also nearby.
Overall, Alafia River State Park is the 28th most popular mountain bike trail of all 58 mountain biking rides in Florida.
