North of Tampa and west of Orlando near Brooksville, these former open quarries left behind over 10 miles of popular mountain bike trails. There are some truly sick descents and some unridable ascents.
To reach the trailhead from Orlando, take SR50 west to Brooksville and turn right on Mundon Hill Road and another right on Cooper Terrace. Look for homemade signage on right. Or, from Tampa, follow US 75 north to Exit 61 and head west towards Brooksville. Turn right on Mundon Hill Road (CR484) and then right again on Cooper Terrace Road.
There is a $3.00 admision fee to use this privately owned facility. Watch out for the poison ivy and oak.
Overall, Gran Canyon is the 8th most popular mountain bike trail of all 58 mountain biking rides in Florida.
