Big Creek Road (Forest Road 370)
Gold rush ghosts and wilderness solitude.
Big Creek Road follows the old supply route that fed mining camps deep in what’s now the Frank Church River of No Return Wilderness. Starting near Yellow Pine, this historic track parallels Big Creek through some of Idaho’s most pristine backcountry, passing remnants of dredges and cabins from the 1900s gold rush. The road ends at Cabin Creek Guard Station, where pack trains once loaded supplies for the remote mining districts deeper in the wilderness.
The 32-mile route rates as moderate difficulty — mostly good gravel with some rocky sections and seasonal washouts near creek crossings. Any stock SUV with decent clearance can handle it, but the remoteness demands preparation. Best driven June through September when snow clears from higher elevations. No permits required, but this is bear country, so secure your food. Multiple dispersed camping spots along Big Creek offer solitude that’s increasingly rare in Idaho’s backcountry.

Frequently asked questions
Can a stock Subaru Outback handle Big Creek Road?
Yes, but barely. The gravel surface is manageable for stock high-clearance SUVs, but you'll be taking it slow through the rougher washboard sections and creek crossings.
Is Big Creek Road passable in early May or late October?
Not reliably. Snow typically blocks higher elevations until June and returns by October, making the June-September window your safest bet for a complete run.
Do I need any permits to drive Forest Road 370?
No permits required for driving, but if you're planning to camp more than 14 days or in large groups, check with Payette National Forest for any restrictions.
What's the most challenging part of this trail?
The creek crossings can be sketchy during spring runoff or after heavy rains. Water levels vary significantly, so scout on foot if you're unsure about depth.
How many miles can I go without cell service on Big Creek Road?
The entire 32-mile stretch has zero cell coverage. Plan accordingly for emergencies and let someone know your timeline before heading into this remote country.
