Poker Jim Ridge Road — Hart Mountain Antelope Refuge High Desert Run
Pronghorn country at 7,000 feet — no crowds, no signal.
Poker Jim Ridge sits on the eastern escarpment of Hart Mountain National Antelope Refuge in south-central Oregon, and the rough two-track that follows it is one of the most isolated drives in the state. The route climbs from the Warner Valley floor onto a broad basalt plateau at nearly 7,000 feet, where pronghorn run in visible herds and the silence is loud enough to notice. From the ridge you get unobstructed views east across the Sheldon Refuge into Nevada and west down the fault scarp toward the Warner Lakes wetlands. The Hart Mountain Hot Spring — a natural 100°F pool tucked behind the refuge campground — is your reward at the end of the road.
This is genuine high-desert backcountry. Carry extra fuel from Lakeview, the nearest town with a pump roughly 65 miles south. The road is rocky and rutted in sections with sharp basalt edges that will find a sidewall if you’re not watching. A high-clearance 4WD is required above the campground approach; stock trucks do fine if you go slow. Snow closes the ridge road from November through May most years. No permit required inside the refuge. Dispersed camping is allowed throughout. Cell service is nonexistent — bring a satellite communicator.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Poker Jim Ridge Road, or do I need a lifted rig?
A stock high-clearance 4WD like a Tacoma or 4Runner is the minimum you want here — this isn't a boulevard, but it's not a rock-crawling trail either. Aired-down tires help on the looser sections and rocky stretches near the ridge. A lifted rig is never a bad idea at 7,000 feet, but it's not required.
When does Poker Jim Ridge Road typically open and close for the season?
June through October is your window. Snow can linger on the ridge well into May and return early in October — at 7,025 feet, the weather doesn't care about your plans. Call the Hart Mountain Refuge office before heading out in shoulder months, the road can be impassable mud even without snow.
Do I need a permit to run this trail or camp in Hart Mountain National Antelope Refuge?
No permit required for driving or dispersed camping inside the refuge. It's managed by U.S. Fish & Wildlife Service and access is free. Respect refuge rules — no off-route driving, campfire restrictions may apply depending on fire conditions.
What's the hardest section of the trail and what should I actually expect?
The upper ridge sections are where it gets real — loose rock, exposed shelf road, and limited room to maneuver if you meet another vehicle. Nothing that demands a locker on a dry day, but wet or icy conditions change that equation fast. The elevation gain is gradual but steady; watch your temps on a hot summer run.
How far is it to the nearest gas, and is there any water on the trail?
Lakeview, OR is your last reliable fuel stop — plan for roughly 80-100 miles round-trip depending on your route, so top off before you leave town. There's a hot spring near Hart Mountain Refuge headquarters that's worth a soak, but don't count on potable water on the trail — carry all you need for the full 1-2 days.
