Carson Pass to Markleeville Backcountry Loop
Sierra Nevada backcountry loop with mining history
Carson Pass sits at 8,574 feet where Kit Carson’s party crossed the Sierra Nevada in 1844, and this loop drops you into some of the most pristine backcountry straddling the California-Nevada border. The route winds through Humboldt-Toiyabe National Forest, past abandoned mining camps like Monitor Pass, before descending into Nevada’s Carson Valley. You’ll navigate rocky volcanic terrain, cross seasonal streams, and thread narrow ridgeline tracks with thousand-foot drops into alpine valleys.
This is moderate to difficult terrain requiring high-clearance 4WD, with loose rock sections and steep grades that’ll test your line choice. Snow blocks the high country from October through June, so plan for July through September. Carry extra fuel—services are 60+ miles apart—and plenty of water for dust and altitude. The payoff is massive: untracked Sierra wilderness, historic mining relics, and some of the most spectacular alpine scenery in Nevada. Dispersed camping is abundant once you’re off the main Forest Service roads.

Frequently asked questions
What kind of clearance and armor do I need for this trail?
High-clearance 4WD minimum with skid plates recommended. Sharp volcanic rock and mining debris can puncture oil pans and sidewalls.
Can I run this trail in spring or fall?
July through September only due to snow at 8900+ feet elevation. Early season snowmelt creates impassable mud conditions.
Do I need permits or pay fees for this route?
No permits required for the trail itself, but dispersed camping follows standard Forest Service 14-day limits in Humboldt-Toiyabe National Forest.
What's the gnarliest section I should be ready for?
The volcanic ridge crossings have loose rock shelves and off-camber descents with serious exposure. One mistake sends you tumbling down the mountainside.
How many water crossings and are they seasonal?
Several seasonal creek crossings that run deep during snowmelt but typically fordable by late July. Bring recovery gear as creek beds have soft sand and hidden rocks.
