Glacier Gorge to Longs Peak Trailhead — Rocky Mountain National Park Backcountry Road
The original road over the Rockies.
Before Trail Ridge Road existed, Old Fall River Road was how people crossed the Rockies in a motor vehicle — and it’s still one of the most raw, exposed drives in the American mountain west. The road runs nine miles one-way from Endovalley Picnic Area near Estes Park up to the Alpine Visitor Center at Fall River Pass, climbing through spruce-fir forest, past cascading Fall River, and eventually breaking out above treeline onto a windswept tundra shelf with nothing between you and the sky. The road is unpaved, single-lane with turnouts, and gains nearly 3,500 feet. Chittenden Trail junction at mile six is a good gauge — if your rig or your nerves are struggling there, the upper switchbacks won’t be any kinder.
This one is accessible to most high-clearance vehicles — a stock SUV or truck handles it fine in good conditions — but steep grades and tight switchbacks mean trailers and large rigs are prohibited. The road is open late June through early October, weather dependent, and requires a Rocky Mountain National Park vehicle pass (timed-entry reservation required during peak season). No dispersed camping is allowed inside the park boundary. Fuel and supplies in Estes Park before you go — there’s nothing inside the park. The payoff is alpine tundra at 11,796 feet with unobstructed views of the Never Summer Range.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this road without modifications?
Yes. Stock high-clearance trucks and SUVs handle Old Fall River Road fine. No lockers or lift needed, but trailers and low-clearance vehicles are prohibited — the NPS enforces this at the entrance.
When does Old Fall River Road actually open each year?
Typically late June, depending on snowpack. It closes by late October or earlier if snow hits. Check the NPS road status page before you go — openings shift year to year.
Do I need a permit to drive this road?
Yes. Rocky Mountain National Park requires a timed entry permit during peak season (generally May through October). Get one at recreation.gov well in advance — they sell out fast.
What's the hardest part of the drive and what should I actually expect?
The road is one-lane, one-way, and climbs 3,500 feet over 9 miles of narrow dirt and gravel. The steeper switchbacks near the top demand attention, but there are no extreme obstacles — the main challenge is exposure and the occasional white-knuckle drop-off with no guardrails.
Is there any gas or services once I leave Estes Park for this road?
None. Fuel up in Estes Park before entry — there's nothing inside the park. Cell service is spotty to nonexistent on the climb, so download offline maps and the NPS app before you head in.
