Grimes Pass Road

Grimes Pass Road is a scenic, easygoing mountain route that winds through the Boise National Forest, just north of Idaho City. This well-graded dirt road traces the historic path of early miners and settlers, crossing through pine-studded ridges and open meadows as it connects the Banks-Lowman Scenic Byway to New Centerville, passing through the historic mining town of Pinoeerville. The elevation tops out around 4,800 feet at Grimes Pass, offering sweeping views of forested hills and the occasional glimpse of distant peaks.

The road is suitable for most vehicles in dry conditions, including stock SUVs and crossovers. While the terrain is generally smooth, occasional washboards, ruts, and potholes may appear depending on recent weather. Numerous spurs branch off the main route, leading to old mining sites, dispersed campsites, and deeper trail networks that offer more challenge for those looking to explore. There aren't any campsites along this specific road, but on Southfork Road in the north, there are great campsites along the Payette River.

Grimes Pass Road is a great choice for newer drivers or anyone looking for a relaxed offroad cruise through classic central Idaho backcountry. It provides a quiet, forested alternative to the busier paved routes and is especially beautiful in the fall when the aspens and larches begin to turn. Keep an eye out for wildlife, historic remnants, and signage marking the area’s Gold Rush past.
