How to get to John Martin Reservoir State Park
The park entrance is near Hasty, Colorado, just off U.S. Highway 50 in Bent County. La Junta is roughly 30 miles west, Lamar about 30 miles east, and Pueblo approximately 110 miles west, a drive of about two hours on mostly flat, straight prairie highway. Because the route is plains driving rather than mountain passes, there are no tunnels, steep grades, or RV weight restrictions of concern, though strong crosswinds are common. The nearest airport with major service is Colorado Springs, about 170 miles northwest, making it a reasonable fly-and-rent option.
