Established in 1915, Rocky Mountain National Park covers 415 square miles about 70 miles northwest of Denver. Trail Ridge Road climbs to 12,183 feet — the highest continuous paved road in the U.S. — and summer entry requires a timed-entry reservation.
In peak season, yes — timed-entry permits apply late May through October; Bear Lake corridor needs its own window.
Buses can drive it, but operators need a commercial use permit and should confirm vehicle length limits.
About 1.5–2 hours to the Estes Park entrances; allow a full day for the park itself.
