Although the State Route 21 Multiuse Path is not scenic, as it closely parallels its namesake roadway, it does provide an important connection between the charming community of Keystone Heights and Gold Head Branch State Park.
The trail begins downtown at a connection with the Palatka-Lake Butler State Trail, which extends nearly 19 miles to the outskirts of Palatka. From that trail intersection, the SR 21 path heads northeast on a paved, diagonal route leading directly to the front entrance of the park. Along the way, a wide grassy median keeps the trail at a comfortable distance from traffic.
There is a nominal fee to enter the park, but it offers a wealth of recreational opportunities, including swimming, canoeing, fishing, picnicking, wildlife viewing, and additional hiking and biking trails.
On the trail's southwestern end, ample parking is available along the main streets of Keystone Heights. On its northeastern end, parking can be found in Gold Head Branch State Park (6239 Florida 21).
