Rocky Mountain in April: what the park service says

April at Rocky Mountain is still before the season for Trail Ridge Road, which stays closed to through travel until late May. Temporary raptor closures can be in place around nest sites of falcons, hawks and eagles; peregrines can dive at over 200 mph and may strike people near a nest. Campground reservations for summer open up to six months ahead. The park lists late May through October, plus winter weekends, among its busiest times, so April is a quieter month to visit.
