Managed by the Florida Office of Greenways and Trails, the Palatka to Lake Butler State Trail corridor stretches nearly 47 miles from the vicinity of SR 238 in Lake Butler to west of US 17 in Palatka along the former Norfolk-Southern Railroad right-of-way (though only a portion of that 47 miles is currently trail.) Construction of the 12-foot-wide, multi-use recreational trail along this corridor is being completed in phases and I biked the entire segment from Grandin to Keystone Heights along highway 100, making a 21 mile round-trip ride.
As with many rail-trails, the trail is lined with trees on both sides for much of its distance, providing shade in sweltering summer weather and shrouding the trail from highway noise, though the trail moves away from Highway 100 for most of its distance. Occasional breaks in the trees remind you of the rural character of the trail with vistas like this...
The trail surface is asphalt in very good condition, especially the newest segment just recently opened.
There are plans to connect St. Augustine to Lake City by way of this trail system making the total length of the Trail over 100 miles, a portion of which will be designated as part of the 1400-mile Florida National Scenic Trail.
No official trailhead parking exists yet, but parking is available along the main street of Keystone Heights as well as the eastern end at Grandin and Highway 100. You can also park at Twin Lakes Park east of Keystone Heights off Twin Lakes Road, and washrooms are available there. Several places in town can also be used for cold beverage and snack/meal purchase if needed.
