Rocky Mountain National Park straddles the Continental Divide roughly 70 miles northwest of Denver, protecting over 415 square miles of peaks, alpine lakes, and tundra. Trail Ridge Road — the highest continuous paved road in North America — connects the park's two gateway towns: Estes Park on the east side and Grand Lake on the west. The park draws over four million visitors a year. Getting there from DIA takes about 90 minutes to Estes Park or three hours to Grand Lake. Timed-entry reservations are required during peak season, and parking inside the park fills early.
Trail Ridge Road is typically open late May through mid-October, depending on snow. Summer is peak season — reserve timed-entry permits in advance. Fall elk rut (September–October) draws wildlife viewers. Winter closes most of Trail Ridge Road but opens cross-country skiing and snowshoeing trails.
