Grimes Creek

This winding dirt road takes you through an area rich in mining history. The first few miles of the road from Highway 21, the Ponderosa Pines Scenic Route, has several nice campsites right along the water. For the last 8 miles, you will pass through an active mining area. This mostly flat and wide drive through the valley is a nice scenic with lots of history. Small potholes and washboard sections...

When to go: Summer and Fall typically offer the best window.

Vehicles: Jeep/Truck, SUV. Standard offroad prep applies: appropriate tires, ground clearance, and a basic recovery kit.

Southwest Idaho context

Southwest Idaho splits across the Snake River. South of the river is Owyhee high desert — sage flats, slickrock canyons, and a million-plus acres of BLM. North is the Boise National Forest, with mining-era roads, ponderosa, and quick out-of-Boise access. Most weekend trips work off Boise, Mountain Home, Marsing, or McCall.

Best for drivers who understand their vehicle and the cost of a mistake in remote country.
