The Hike

While hiking Summit Trail is a fantastic and beautiful forested hike in and of itself, attaining the summit of Slate Mountain yields one of the very best vistas in the Southern Sierra. One could spend hours looking at all that it offers: the basin of the Tule River, the dramatic peaks of the Great Western Divide, the highest sierra peaks in the Mt Whitney group, Olancha Peak, Kern Peak, The Hermit and Needles are all just some of the amazing features to look for.

On the Summit Trail

On the Summit Trail.

Slate Mountain does have slate and a variety of metamorphic rock, which is unique in a land of granite. This seems to allow for a variety of wildflowers and plants that are not always present on some of the other hikes in the region.

One may hike Summit Trail from Quaking Aspen Campground, or from the Windy Gap trailhead from the south, or hike point to point with a shuttle.

The Hike Up to Slate Mountain

Directions to the two separate trailheads on Summit National Recreation Trail, 31E14, are described below.

Note that this is a multi-use trail and both horseriders and mountain bikers occasionally ride all sections of the Summit Trail.

The trailhead at Quaking Aspen Campground is the most popular and also offers access to Yokut Spire.

The more remote Windy Gap trailhead is also an excellent (and slightly easier) option with possible side-excursions to Freezeout Meadow and to an impressive subpeak, 8769.

These are all shown on the Kern River Sierra Map.

Quaking Aspen

If commencing at Quaking Aspen, find the trailhead parking just east of the campground (this is also the top of Nelson Trail). There is also access behind the campground (on the south side) between campsite #23 and #24.

The trail soon starts ascending and crosses a paved access road. Stay on the main trail as some other use trails merge in from the Ponderosa area. The route passes by some meadows of golden currant and forest of pine and red fir as it ascends. After a series of switchbacks, the trail passes a wonderful viewpoint of The Needles.

Near the 8500 foot level, one can traverse the ridge to find Yokut Spire.

As the trail nears the top, it intersects with Bear Creek Trail off to the right. At this point some people climb directly up to the peak on the left. A possibly better option is to continue on the trail as it wraps around the backside almost .2 miles. Often, there is cairn marking a good spot to leave the trail below a large slope of boulders. Hiking up this avoids any brush crashing.

The rock-strewn summit contains a register and some surrounding trees for shade. Hiking back down the ridge to the north provides some of the very best views. Depending on where one started the hike, it's up to 5.5 miles to the summit.

Windy Gap

If commencing at Windy Gap Trailhead off Crawford Road, take the trail leading north into the woods. (The trailhead is actually located a little past the saddle of Windy Gap to the east.)

The trail traverses the east side of the slope before switchbacking up to the main ridge. Here a use-trail leads out to Peak 8769. Continuing on Summit Trail, the hiking follows the ridgeline north, and passes Freezeout Meadow, which is on the right and not visible from the trail. Keep following the trail through a beautiful forest and look for a use-trail on the right leading up to the summit (see the description above). The peak is about 5 miles from the trailhead.

Other Options

Rock climbing: Some people have rock climbed the 500 foot volcanic Yokut Spire. Most do a class 3 route with great holds, but a lot of exposure. There are two known climbs according to E.C. Joe; Donut Dunk and The Prow. Both are 3 pitches and 5.8 in the old guide book.

Skiing: Slate Mountain was the site of a proposed Ski Resort, with 14 lifts in the plans. If you like to earn your turns, this is an awesome spot!

Keep Hiking: The Summit Trail continues on both ends of the hike described here, although it receives less maintenance. Another option is to drop a car at Coy Flat, and hike down Bear Creek Trail.
