Trail Information


National Forest route M1 (also known as Elk Mountain Road) is the main south-to-north arterial that acts as the "spine" of the Mendocino National Forest. Seemingly endless single-track OHV trails (bikes and quads only) and double-track trails wide enough (and signed for) street-legal 4WD vehicles branch off regularly as you travel along the M1. For this reason we have documented its many intersections as comprehensively as possible, with a waypoint for each one. Note that the "Ranch" fire of 2018 closed many of the trails in this area; the BLM has been working hard to get them reopened, but many of the single-track OHV-only trails are still closed for repair.

Drove this trail on the way to the connecting hull mountain trail. Was in good condition, and a few 'side quest' roads were open too. Tons of motorbike / ohv opportunities

M1 was easy as described and weather had been beautiful so 4WD or high clearance wasn't even necessary but did make for a nicer drive. Much of the forest is scarred from the awful fires but beauty can still be found all around. We ended up staying at Lake Pillsbury for the weekend. It's an improved campground for $10/night and amenities included tables, fire rings and bathrooms. The camp filled up by Friday night and emptied out by Sunday so our extra stay through Monday was very peaceful. Nice campground with ample space between sites. Normally there's water at the campground but water wasn't available this particular weekend so good thing we brought our own. We saw a herd of elk in the early AM on Monday. M1 continues much further north to the Eel River but we didn't have the time to explore beyond the lake.

Basic dirt road, well graded. One of the better access roads to get to Lake Pillsbury and MNF

This is basically a dirt road (washboard) to Pillsbury Lake and acres into the nicer trails of Mendocino National Forest. There are some turn off sections mainly for dirt bikes. Might get a bit tricky when raining in winter. But over all a very easy road great for your first off road experience.
