Is it right for you?
Tuttle Mountain sits on the north side of California Gulch, west of Animas Forks above Silverton. With a vehicle that has decent clearance, it is a short, quick hike.
You start from a pull-off on the California Gulch road and climb steep grass and flower slopes on a diagonal past an old mine to a small basin on the ridge, then on to the summit. It is Class 2. The slope is steep but the footing is mostly secure.
The round trip is about 1.5 miles with 1,385 feet of gain from the upper parking; starting from the Placer Gulch junction adds about 1.4 miles of road walking. Houghton Mountain, east along a broad ridge, makes a good pairing.

Steady, steep grass.
Easy, but the true summit can be confusing from the ridge.
None on the route. Carry what you need.

Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Getting there
California Gulch parking
From Silverton, drive east through town. A block beyond the courthouse the paved road splits; bear right onto County Road 2, which has a blue sign. It is also called the Alpine Loop road. Pavement ends after about 2 miles, and good dirt road goes on to Howardsville at 4.2 miles. Keep north 4.3 more miles to the old Eureka site. Past there the road switches to the river's west bank, climbs a steeper shelf and runs up a narrower part of the canyon.
Near 10,740 feet the valley widens and the Picayne Gulch road goes left. Its lower part is very steep and only for 4WD vehicles with low gearing. Most people stay on the main road and take the left turn to Animas Forks; the first of the two turnoffs drops across the river and climbs up to the old mining town. From there head west on County Road 19 (BLM 4505). Maps disagree on whether this road needs 4WD; a high-clearance vehicle is wise. After 1.2 miles you reach the Placer Gulch road (County Road 9) on the left. This junction with California Gulch is the trailhead.
For Tuttle and Houghton, drive 0.7 mile farther west on County Road 19 and park on the left where the road splits for a short way, out of the path of the many ATVs and jeeps. You can also start from the Placer Gulch junction and walk the road. There are no Forest Service campgrounds nearby. Eureka has a pay campground that takes reservations, and there are primitive sites on the spur road to the South Fork of the Animas (Boulder Gulch) trailhead. None have services.
