The South Fork Trail is one of the more popular routes to the San Gorgonio Mountain summit, and for a good reason. You have to put some work in on the climb, but overall the gradients are steady and reasonable. As you wind up toward the summit, you’ll get postcard views of the San Bernardino high line of peaks, views down to Mill Creek, and then, of course, the epic views from the summit, the highest point in southern California. Overall this is a classic hike.

Where is the South Fork Trail?

The start of the South Fork Trail is easily accessible by paved road, and has a large parking area. Use this trailhead address:
South Fork Trail 1E04, 40800-40894 Jenks Lake Rd W, Angelus Oaks, CA 92305

South Fork Trail Directions 4
There’s a parking area right by the trailhead and then some other lots further down. Drive clockwise as you enter the parking area.

You need a National Parks Pass or Adventure Pass to park here.

South Fork Trail Directions 5
There’s a bathroom at the trailhead.
South Fork Trail Directions 1
Look for the trail board at the far end of the parking area.

Permits for the Fish Creek Trail

The San Gorgonio Wilderness Association handles South Fork Trail permits, and they are easy to apply for using their online portal. There’s a quota system, and this trail can get busy on the weekends, so try to book ahead. You can print your permit out or save it to your phone (as long as your phone works). You can also get an overnight permit and make the trip a backpacking adventure. You must camp in the designated campsites, and the only ones directly on this route are Dollar Lake and Dry Lake View (my pick).

Gear For the Hike

South Fork Trail Directions 3
Some of the trail can be overgrown. Having long pants will save your legs from scrapes and scratches.

Garmin Inreach Mini 2

Garmin InReach Mini 2
I’m a firm believer in carrying a satellite communications device which works where cell phones don’t. I use a Garmin InReach which lets me send text messages back and forth to my family to let them know that I’m okay or if my plans change when I’m out in the backcountry. It also has an SOS subscription built-in so that you can reach first-responders in an emergency. The devices also offer weather reports, GPS, and navigation functionality (what’s the difference between a GPS and satellite communicator?). For a few hundred bucks they could save your life, so for me it’s a no brainer to have something like a Garmin InReach. If you use a smartphone to navigate and want a more affordable option that integrates with your phone easily, check out the ZOLEO.

Lone Peak 6 Yellow

Altra Lone Peak 6
For most people, the Altra Lone Peak is a solid choice that will leave your feet feeling great at the end of any hike. The feel is cushy and light, and if it had a car equivalent, this would be a Cadillac or Mercedes Sedan. The grip is great and they’re reasonably durable for this type of trail runner, which I think is better in most conditions than a hiking boot, and here’s why. The downside of this shoe is that it won’t last as long as something like the Moab 2 (see alternate footwear choices at the bottom of my gear page). I’ve been using mine for many miles and my feet always feel great. I have a video on the details of the Altra Lone Peak 6 here.

Black Diamond Ergo Poles 2

Black Diamond Trail Ergo Cork Trekking Poles
I’ve gone back and forth on trekking poles, but I think for most people they are a good investment. They help you dig in on the uphills, provide stability on loose downhills, act as a brace when crossing streams, and can probably poke away aggressive wildlife in a pinch. The Trail Ergo Cork poles are a good balance of light weight, durability, affordability, and ease of use. If you want something ultralight and a little more pricey, I’ve had great luck with the Black Diamond Z Poles too.

Gregory Zulu 30

Gregory Zulu 30 & Jade 28
After testing quite a few backpacks, the Gregory Zulu 30 (and Jade 28 for women) is, for most hikers, the best all-season day-pack. First off, it’s very comfortable, and the mesh “trampoline” back keeps your back dry. Its 30L capacity is enough for all the essentials and plenty of layers for winter hiking. External pockets make it easy to grab gear. It’s hard to find something wrong with the pack; if anything, it could be a bit lighter, but overall, it’s not heavy. And its price-point makes it not only affordable but generally a great value.

South Fork Trail Maps

South Fork Trail Directions 2
Most of this trail was heavily impacted by the 2015 Lake Fire. All the dead trees that you see will eventually fall down, and some have already. There can be big trees across the trail, and usually when there are, other hikers create detours around. The Forest Service and their volunteers actively maintain the trail and keep it clear (with non-powered tools). Thank them if you see them.

How Are You Going to Navigate This Hike?
Here’s what I use. If you are a hardcore hiker and/or hike in extreme conditions, I recommend getting a dedicated GPS like a GPSMAP 66sr or 66i, or a wrist-based GPS with maps like the Garmin Fenix 7 or Epix. If you only hike in fair weather and a touchscreen is fine, or just want a solid tool, I highly recommend downloading the smartphone app, Gaia GPS. It’s a piece of cake to use and very powerful, just make sure your phone is in airplane mode so the battery doesn’t drain. You can also check for wildfires, weather, snow, and choose from dozens of map types with a premium membership (HikingGuy readers get a big discount here). Note that I also carry a paper map with me in case the phone dies or gets smashed.

The first third follows the South Fork of the Santa Ana River, then you bear right and hike up to Dollar Lake Saddle. From there the trail winds along the high ridge to the San Gorgonio summit.

Lollipop Route

South Fork Trail To San Gorgonio Mountain Alt Route
If you want to add 2 miles onto the route, you can try the alternate “lollipop” route, shown here in red.

Another popular route is combining the South Fork Trail with the Sky High Trail and hiking them in a loop. It’s typically done as a clockwise route. If you’re cool with the mileage, or have done the South Fork Trail up and down, I recommend giving it a try. Here’s how to put the pieces together:

  1. Hike to Dry Lake on the South Fork Trail.
  2. From Dry Lake, hike up to Mine Shaft Saddle.
  3. Take the Sky High Trail to the summit.
  4. Descend on the South Fork Trail (on the route described in this guide, but in reverse).

If you take this route, there are a good amount of overnighting options. The most popular being Dry Lake and Mine Shaft Saddle. If you overnight, remember to get your permit.

Turn by Turn Directions

South Fork Trail Directions 6
Hike past the trail board and bathroom.
South Fork Trail Directions 7
Cross Jenks Lake Road.
South Fork Trail Directions 8
And you’ll see the official start of the South Fork Trail.
South Fork Trail Directions 9
Go down and then up the other side of the creek (which isn’t the South Fork).
South Fork Trail Directions 10
In the beginning the trail is very steep.
South Fork Trail Directions 11
But then levels out and climbs gradually. You’ll see lots of evidence of the 2015 Lake Fire, which was devastating to the area. The fire, a suspected case of arson, could have been contained sooner, but air operations had to be stopped when a drone was spotted flying around the fire.

To see what this area could potentially look like after 50 years of recovery, check out the nearby Exploration Trail, which has recovered from the 1970 Bear Fire.

South Fork Trail Directions 12
Keep hiking uphill on the trail.
South Fork Trail Directions 13
And when you get to Horse Meadows at the top of the hill, bear to the right.
South Fork Trail Directions 14
You’ll see some historic cabins on the left. If you want to learn more about them and see inside the cabin, check out my guide to Dry Lake.
South Fork Trail Directions 15
Keep hiking straight through the old road. Before the area ahead had an official wilderness designation, you could drive up here.
South Fork Trail Directions 16
The trail starts angling uphill.
South Fork Trail Directions 17
Hike over the old road, which is only open to Forest Service vehicles.
South Fork Trail Directions 18
The trail crosses dozens of small streams that feed the Santa Ana River watershed. It can get overgrown.
South Fork Trail Directions 19
As you climb you’ll get glimpses of Sugarloaf Mountain, the highest point on the other side of the valley.
South Fork Trail Directions 21
At the top of the hill you’ll see a junction. On the left is the side trail to the infamous Poopout Hill. Officially renamed in 1966 to honor those who came this far, saw San Gorgonio in the distance, and bailed out. The road used to come up to the hill, and Poopout Hill used to be called Trail Head Hill. Go straight to continue the hike.
South Fork Trail Directions 22
You’ll pass the San Gorgonio Wilderness sign. You need a permit past this point. The trail then goes downhill and then levels out, giving your legs a break.

Did you know that in the great hiking era of the 1920s, President Calvin Coolidge was lobbied to protect this area by creating the “Junípero Serra National Monument”? It never happened, but today it’s protected as an official wilderness area.

South Fork Trail Directions 23
As you cruise on the flat section, you’ll see your final destination, San Gorgonio Mountain summit, in front of you. On the left you’ll probably hear the roaring of the South Fork of the Santa Ana River. The area to the left is also called Slushy Meadow because of all the streams and springs supplying the river, which eventually flows out to the ocean at Huntingdon Beach.
South Fork Trail Directions 24
At about 3.4 miles in you’ll see the faint trace of the Lost Creek Trail on the left, which is mostly overgrown and impassable since the Lake Fire.
South Fork Trail Directions 25
After the Lost Creek Trail, the South Fork Trail starts to angle upward. Here we go.
South Fork Trail Directions 26
At the junction with the trail to Dry Lake, make the right towards Dollar Lake.
South Fork Trail Directions 27
The climb angles up some more, and the trail surface is rocky. You’ve got about 2.4 miles and 1800 feet of climbing to Dollar Lake Saddle.
South Fork Trail Directions 28
The gradient eases up in spots and the trail gets a little easier on the feet.
South Fork Trail Directions 29
As you come around the switchbacks you’ll see San Gorgonio in front of you. as well as Grinnell Mountain on the left. The area up to the left is directly above Dry Lake, and you hike up there on the approach from Fish Creek.
South Fork Trail Directions 30
The trail turns around and you’ll see the notch that is Dollar Lake Saddle head to the left.
South Fork Trail Directions 31
At the turnoff to Dollar Lake, stay right to continue to the saddle.

Dollar Lake, named after its grey bottom makes it look like a silver dollar, is fed by a spring and has water early in the season (generally). And Dollar Lake is a tarn, a lake formed in a cirque (bowl) by a glacier. The San Bernardinos are the only mountains in Southern California that show evidence of glaciers. The lake is 0.5 miles down the spur trail if you want to visit.

South Fork Trail Directions 32
When you get to Dollar Lake Saddle, above the lake, hike on the trail to the left.
South Fork Trail Directions 33
There’s a Yosemite-style trail sign at the saddle. This is also the official end of the South Fork Trail; we’re now on the San Bernardino Peak Divide Trail.
South Fork Trail Directions 34
The trail starts going up through the pines.
South Fork Trail Directions 35
And soon you’ll get incredible views of the San Bernardino high line. From left to right: San Bernardino Peak, Andersen Peak, and Shields Peak.
South Fork Trail Directions 36
And then the trail winds around to the south, and you can see the peaks above Mill Creek, including Little San Gorgonio Peak. If you’ve ever hiked to the summit on the Vivian Creek Trail, you started down there.
South Fork Trail Directions 37
The trail is rocky and steadily uphill as you climb up above 10000 feet and around Charlton Peak, which is on your left. The peak is named after R.H. Charlton, the Angeles National Forest supervisor from 1905-1925. In front of you is Jespon Peak, named after Willis Jepson, one of the founding members of the Sierra Club, along with John Muir.
South Fork Trail Directions 38
At about 7 miles and 10500 feet you pass through Dry Lake View Camp at a picturesque saddle.
South Fork Trail Directions 39
There are some protected tent sites here.
South Fork Trail Directions 40
If you look down to the left from the saddle, you can see Dry Lake (it’s dry here).
South Fork Trail Directions 41
Continue up from the saddle area.
South Fork Trail Directions 42
The landscape becomes more barren as you leave the tree line behind and round Jepson Peak.
South Fork Trail Directions 43
As you swing around to the south you’ll see the ridge where the Vivian Creek Trail climbs toward the summit.
South Fork Trail Directions 44
And as you round Jepson Peak, you’ll start to see San Gorgonio Mountain in front of you.
South Fork Trail Directions 45
The trees are gone as you hike along the ridge. Several “window” areas allow you to view down to the left.
South Fork Trail Directions 46
To the left, through the “windows,” you’ll be able to see Dry Lake, South Fork Meadows, and the approach you took on the way up.
South Fork Trail Directions 47
When you get to the junction with the Vivian Creek Trail, go straight.
South Fork Trail Directions 48
Here’s the sign at that junction. We’re going to Summit Camp.
South Fork Trail Directions 49
And soon after that is the junction with the Sky High Trail. Go straight toward the summit.
South Fork Trail Directions 50
Here’s a closeup of the sign at that junction. We’re going toward San Gorgonio Mountain.
South Fork Trail Directions 51
And then you’ll see the summit in front of you.
South Fork Trail Directions 52
At the top, make the left to climb the last pile of granite.
South Fork Trail Directions 53
And that’s it, you made it to the summit!
