Mount San Jacinto: Southern California’s Favorite Peak

“San Jacinto is the most sublime specticale to be found on this earth!”

– John Muir

Muir, the great environmentalist, mountain climber, and founder of the Sierra Club, was right – Mount San Jacinto is sublime.

To be succinct, my partner, CT, has often called it her “happy place.”

Mount San Jacinto in Southern California is not your first thought when thinking of the California lifestyle.

Known for sunshine, sandy beaches, surfing, Hollywood, and amusement parks, the Golden State's southern half is also filled with mountains and snowy peaks.

There are more than 26 named peaks in the area over 10,000 feet (3,226 meters) in elevation.

My partner CT and I have climbed to the top of all 26, but our favorite one is the highest point on the San Jacinto massive.

The peak is 10,834 feet high (3,611 meters) and is accessible from seven different trails.

If you are hardy, fearless, and not afraid of the cold – the mountain can be climbed all year long.

The view from the top of Mount San Jacinto goes in all directions and for many hundreds of miles.

We have seen the Pacific Ocean, parts of Mexico, the Sultan Sea, and Telescope Peak in Death Valley.

Hiking to the top of Mount San Jacinto can be done by starting from either side of the mountain.

The resort city of Palm Springs sits at the base of the mountain and is on the east side, and the little town of Idyllwild is on the west side.

Choose either side, and it is a 2.5-hour drive from San Diego or a 3-hour drive from Los Angeles.

Every trailhead I list below is accessible through Google Maps, which will guide you directly to the parking area.

I have climbed to the summit of more than 430 mountains over the last seven years, but only a few peaks get a second hike.

Conversely, since I have climbed Mount San Jacinto 21 times, I can say it is my favorite mountain.

San Jacinto Routes to the Top

Climbing Mount San Jacinto never gets boring.

There are eight routes to the top, and we have done seven of them.

  • Via the Palm Springs Aerial Tramway / Round Trip 11 miles (17.8 kilometers) Elevation gain 2,200 feet (709 meters).
  • Marion Mountain Trail / RT 11 miles (17.8 kilometers) Elevation gain 4,500 feet (1,451 meters).
  • Skyline Trail or Cactus to Clouds RT 30 miles (48.3 kilometers) Elevation gain 10,100 feet (3,258 meters).
  • Deer Springs Trail / RT 19 miles (30.6 kilometers) Elevation gain 5,121 feet (1,652 meters).
  • Devil's Slide Trail / RT 16 miles (26 kilometers) Elevation gain 4,410 feet (1,422 meters).
  • Fuller Ridge Trail / RT 15 miles (24.2 kilometers) Elevation gain 3,950 feet (1,274 meters).
  • South Ridge Trail / RT 20.5 miles (33 kilometers) Elevation gain 6,500 feet (2,100 meters).

In addition to trying many of the trails to the top, we often used a snowshoe route in the winter when all the trails and bushes were covered in snow.

By using snowshoes, crampons, or even just microspikes, we were able to hike Mount San Jacinto's summit every month of the year.

Some of the trips we made in the winter were thrilling, and some were brutally cold and miserable. Each of them was memorable.

If there had been a recent snowfall, we would wear snowshoes the whole way.

By springtime, the snow had begun to melt and become hard ice as it froze each night.

Under these conditions, we used crampons and an ice axe.

We have started our journey to the peak via the Palm Springs Aerial Tramway more than ten times.

This is a ride that not only takes time off of the hike but makes for a safer and more reasonable hike in winter.

It is not uncommon to be in line for the first ride up the tram and see a dozen or more folks ready with snowshoes to try for the summit of Mount San Jacinto.

The Tram is not just for crazy summit hikers, though.

Thousands of people each day take the tramway up to 8,500 feet for the viewing decks, to eat and drink in the restaurants, to play in the snow, or take a stroll through the easy trails in Mount San Jacinto State Park.

The Tram is billed as the world's largest rotating tramcar, and it takes guests 2.5 miles up the mountain in less than 15 minutes.

It is a great place to start a hike to the summit of San Jacinto Peak too.

Mt. San Jacinto Camping

CT and I have stayed in Idyllwild on many occasions before climbing one of the peaks on San Jacinto.

We have stayed at a friend's cabin twice, and twice we have stayed at a small hotel in Idllywild.

We have tent camped at two places on the west side of San Jacinto near Idyllwild as well.

Idyllwild County Park: is a Riverside County-owned campground for RV and tent camping with 88 sites. We stayed here and hiked right out of the camp to the Deer Springs Trail and made it a long 24 mile (39 kilometer) round trip hike to the peak and back.

Marion Mountain Campground: is the most secluded and pleasant of all the choices. It comprises just 24 sites and is at the trailhead for the Marion Trail to the peak. We stayed at campsite number 20, the best site in the campground.

Other sites for tent and RV camping at the base of the mountain include:

  • Idyllwild Campground at Mt. San Jacinto State Park
  • Stone Creek Campground
  • Boulder Basin Campground
  • Hurkey Creek Campground (best is you have a large recreational vehicle)
  • Yellow Post Campsites: are a good choice for primitive camping. There are no services or water, but the camping is free.

Twice we have backpacked into San Jacinto State Park and pitched a tent in the wilderness area.

While I have seen tents pitched in various places on the mountain, the three spots set aside for camping are Little Round Valley, Round Valley, and Tamarack Valley.

The official rules are designed to keep control of the degradation of the wilderness and keep guests safe.

Permits and Fees

Permits are required to hike into the wilderness areas of Mount San Jacinto State Park, which includes the peak.

There is no permit fee, but volunteers and official rangers will check for permits on the trail.

If you plan to hike from the western side, permits are obtained at the Idyllwild Ranger Station at 25905 Hyw 243 Idyllwild, CA 92549.

Pick them up the day before your hike, or get there early as the permits are limited.

If you ride the tram up the mountain or you hike from the east side, you will need to stop in the ranger station at Long Valley after getting off the tram to pick up and fill out a wilderness permit.

A backcountry wilderness permit is needed to backpack into the wilderness and stay the night, and a $5 per person fee is required.

Staying Safe on the Mountain

During the summer months, the peak and the trails will be crawling with people trying to reach the peak.

We have been on the summit on a summer's day with perhaps 50 people crowding the boulders at the top.

As long as you bring enough water and stay on the trail, you will be in good shape.

However, if you decide to climb this peak in the dead of winter as we did, be ready and trained to take care of yourself.

There have been many days when we hiked to the summit in winter, and we were the only people on the peak for hours.

Avalanches and slipping and sliding to one's death on the mountain slopes are a possibility.

We found that the best trip reports come from a blog called

He hikes to the peak several hundred times per year and runs the blog to inform folks about the mountain and the current conditions.

Whatever your dreams may be when it comes to climbing mountains – Mount San Jacinto can fulfill nearly anyone's climbing fantasies.

Great writeup and thanks for a fun trip down memory lane. I went to summer camp near Mountain Center when I was 11 and 12, that's a bit over half a century ago. Climbing Sanjac was very challenging as a boy and I remember traversing Devil's Slide too. In fact we did several multi day pack trips around the area and I totally fell in love with it all! I still do the occasional peak. In fact my wife and I are training up to climb Mount Kinabalu when we go to Malaysian Borneo the end of March, hopefully the border will be open then.

Thanks for the reply. Your trip to Borneo sounds amazing.
