Chimney Rock to Dolores River Canyon — McPhee Reservoir to Cahone via Disappointment Valley
Colorado canyon country with zero crowds.
Drop west out of Dolores on County Road 141 and the pavement gives way fast. You’re rolling through Disappointment Valley — named by prospectors who found no gold here — a wide alkali flat ringed by low red mesas that stretch toward Utah like they have no intention of stopping. The Dolores River cuts through sandstone below the valley rim, and the dirt roads tracing the canyon edge offer some of the most underrated canyon country driving in Colorado. Chimney Rock spire stands as a useful landmark in the middle distance. Side roads peel off toward dispersed camps above the river, and the Slick Rock area at the far end of the valley puts you right at the edge of canyon country before the Utah border.
This is moderate overland terrain — wash crossings can get soft after rain and the clay-heavy road surfaces turn greasy when wet. High-clearance 4WD is the minimum; a locker helps in the muddier stretches after storms. Best run May through June or September through October — summer heat is punishing and monsoon mud closes roads. No permit required. Fuel in Dolores before you leave; cell service is nonexistent once you drop into the valley. Water sources are scarce — carry your own. Dispersed camping is wide open on BLM land throughout the valley.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this trail, or do I need a lift?
A stock high-clearance 4WD like a Tacoma or 4Runner is the minimum and will get through fine under normal conditions. Lockers aren't required, but if the dirt surface is wet, it gets greasy fast — mud tires help. Don't attempt it in a stock crossover or 2WD truck.
When is this trail actually drivable, and what happens if it rains?
Best windows are May–June and September–October. The dirt and clay sections in Disappointment Valley turn into a slick, tire-packing mess after rain — not just 'rough,' but genuinely impassable. Check forecasts before you leave Dolores and be ready to wait it out or bail.
Do I need a permit to run this route or camp along it?
No permit required. The route crosses BLM land managed by the Dolores Field Office, and dispersed camping is free under standard BLM rules — 14-day stay limit, 300 feet from water sources and roads. No fees, no reservation system.
What's the hardest section and what should I actually be ready for?
Nothing on this trail is a rock-crawling challenge — the difficulty is remoteness and surface conditions, not technical obstacles. The roughest stretches are rutted two-track through the sage flats where washboards and soft shoulders can catch you off guard. Airing down to 25–28 psi makes a real difference in comfort and control.
How far is the nearest gas, and is there reliable water along the route?
Fill up in Dolores before you leave — there's no gas along the 48-mile route, and the nearest station past the end near Cahone is slim. Water crossings exist but treat any water you pull from the route; the Dolores River area has livestock grazing and no water is potable without filtration. Carry more than you think you need.
