Located just outside of Idyllwild, CA in San Bernardino National Forest, the Black Mountain Trail hike to the fire lookout is a hidden gem. Often overshadowed by hikes like Tahquitz, it offers a healthy mountain climb, great panoramic views, a fire lookout, AND a secret grove of Giant Sequoia trees. You heard that correctly.

Getting to the Trailhead

First off, there are about 50 million "Black Mountain Trails" out there, so make sure you are using the one designated as 2E35 in San Bernardino National Forest before the GPS routes you to South Dakota. Use this trailhead address:
Black Mountain Trail 2E35, 4S57, 2E35, Banning, CA 92220

The parking lot is big, but usually fills up as the day goes on. The trailhead is at the far end of the lot. You don't need any parking pass here according to the SBNF website.

There are no bathrooms or water at the trailhead.

Gear For the Hike

The trail is a legit mountain climb, so you should use proper hiking gear on this hike. Trekking poles help you going up and down the steep slopes. Like most of the high mountains of Southern California, in the summer it can get very hot, and in the winter the trail can be covered with snow. Check the conditions before you go.

Hike Brief

Black Mountain Trail Directions 31
This hike includes a short visit to Boulder Basin campground. You could overnight here if you're feeling it. Note that the campground is also accessible by a dirt road.
  • A fire tower has been on Black Mountain (7,772 feet) since 1926, but the one you see now was built in 1962. It's staffed by volunteers and you can usually go up and have a look around, but please be polite and respectful.
  • There are 50 "Black Mountains" in the geographic registry for California. The official name of this peak is "Black Mountain #1" since it's the tallest of the 8 "Black Mountains" in southern California.
  • There are some good bouldering spots along the Black Mountain Trail. Look for hikers with big mats on their back. They are going bouldering.
  • The trailhead is close to the fire station, which is home to the Vista Grande Hotshots, and you can sometimes see them training on this trail. They hike up  and down carrying their fire gear. Those guys are tough.
  • Okay, let's talk about the giant sequoias. In 1974 in nearby Hall Canyon, there was a fire, and afterwards the Forest Service planted about 150 giant sequoias there. Today they are growing, scattered around the Black Mountain Trail. Don't expect to see huge trees like Grizzly Giant, but if you know what to look for, you can spot some. If you want a full rundown of all the tree positions and their (re)discovery, read this study by Mena and Rudold Schmid.

And after a short while you'll emerge from the chaparral and start getting some views.
Black Mountain Trail Directions 8
Big trees! But is it a giant sequoia? Look for bright reddish bark, egg-shaped cones, and scale-like needles. And don't look for giant trees. Since these were planted in 1974, they should be under 50 feet.
Black Mountain Trail Directions 9
The trail levels off and heads through a boulder field. The next mile or so has some ups and downs, but is not as steep as the beginning.
Black Mountain Trail Directions 10
The trail heads through some sections of vegetation. Most of the hike is in the shade.
