Great Falls National Park Professional Review and Guide
"Great Falls is one of the United States' most popular national parks. How appropriate then for it to be located just 14 miles from our nation's capital. And what a thrill for cyclists to know that mountain biking is not only allowed at the park-it's welcome. Great Falls is a natural haven for thousands of Washingtonians seeking solitude from the daily grind of gridlock and government.
Trails abound throughout this park on the river, offering cyclists, hikers, and equestrians alike terrain as rugged on land as it is in the water. some portions of the park's trails are wide, dirt carriage roads dating back through history and meandering through the scenery, while others are steep, rocky, and narrow, keeping even agile cyclists on the tips of their seat. Trail Surface: Rocky, dirt trails and carriage roads."
