Hiking Saddleback Mountain takes you to the highest point in Orange County, Santiago Peak. It’s also the highest point in the Santa Ana mountains at 5,689 feet. This hike takes the scenic Holy Jim Trail, which is also the shortest route to the summit. This is a long and challenging hike. Don’t try this hike without a good level of fitness.

Saddleback Mountain is actually two peaks, Santiago Peak and the lower Modjeska Peak. Saddleback Mountain can be seen from most of Orange County and dominates the skyline. It’s called Saddleback Mountain because the two peaks look like a saddle from most of Orange County. This hike goes to the higher Santiago Peak, but you can also hike to the lower Modjeska Peak.

Santiago Peak is named after Santiago Creek, which starts on the upper slopes of the mountains and then flows into the Santa Ana River, eventually joining the ocean at Huntingdon Beach.

The Holy Jim Fire has closed this hike for the near future. Try the nearby Sitton Peak Hike which offers great views as well.

How to Get to the Saddleback Mountain Hike

Use this GPS address: Main Parking for Holy Jim Falls and Trail, Corona, CA, 92883, USA.

Getting to the Holy Jim trailhead is half the fun. It’s a dirt road for about 6 miles, and is best done in 4×4. You can do it in a car, but some sections are very rutted and require a careful (and slow) drive.

The directions to the Holy Jim trailhead will bring you onto the dirt road. This is the start of it.
sign for the Holy Jim Trail
A few miles in on the drive, you’ll see a sign for the Holy Jim Trail. The road gets more rutted here.
Holy Jim Trailhead sign
When you get to the trailhead, there’s an incorrect sign pointing back the way you came for parking. Ignore and park in the lot around the Holy Jim Trailhead sign.

You need a parking pass for the Cleveland National Forest. I use the affordable National Parks Pass, which gets me in every national park, national monument, and national forest. You can also use an (Southern California only) Adventure Pass, or buy a $5 day permit from the ranger’s office.

Gear for the Hike

This is a tough hike and you need to be well prepared with layers, water, and food. The upper slopes are generally free of snow, making it a good mountain hike for the winter. It does occasionally snow on Saddleback Mountain however, so check the weather. In the summer it can be brutally hot as well. Go early in summer months to avoid the worst of it.

Here’s the gear that I personally use, have tested, and recommend for this hike*.

Osprey Talon

Osprey Talon 33

My best lightweight pack for hikes between 3-10+ hours. I use mine with the 3L water bladder from Osprey.

You can text, SOS, and get weather in the backcountry where your cell phone doesn’t work. Literally a life-saver.

If you’re hiking in the backcountry it makes sense to have a decent emergency kit and some basic gear to spend the night in a pinch.Full HikingGuy Gear List

Gaia GPS

Gaia GPS is a planning and navigation tool that you can use on your phone, tablet, and the web. I use it on my phone when I need to interact with the map and know where my position is on it. I use it at home on the computer to plan routes. You can overlay maps such as public lands to find out free places to camp. It’s a powerful tool.

Topo Maps & Guide Books

Don’t be caught out if your batteries die. Take a topo map with you on the trail. Some people also print my guides out for use on the hike.

I also highly recommend taking a map and compass navigation course. It’s a few hours, it’s fun, and it could save your life.

Don’t just rely on a cell phone, especially if you are hiking in the backcountry.

Santiago Peak is the highest point in Orange County, so plan on going up. There are a few sections to catch your breath. The first half of the hike is gentler than the second half.

The radio antennas on the Santiago Peak summit look so close, but you still have some work to do on the hike.

You did it, Santiago Peak!
path to summit on saddleback
So the summit can get a bit tricky. There are a lot of roads and tower areas. This satellite map shows you the path to the summit marker.

When you first get to the summit area, stay right toward the higher towers.

At the other side of the summit you’ll see this little building. Continue around the side of it for the actual summit.
path to summit on saddleback
This little trail brings you up the summit. Pretty anticlimactic after the miles you just did, but who cares!
path to summit on saddleback
THE SUMMIT OF SANTIAGO PEAK! You did it. There’s a trail register and sometimes a wood summit sign.
cris hazzard on Saddleback Mountain
Take your selfies and head back down the way you came. My recommendation would be to skip going down the Upper Holy Jim Trail and just continue down the Main Divide Road until you reach the (lower) Holy Jim Trail.
