If you want a great Angeles National Forest mountain hike without the crowds, hike Ontario Peak (8,696 ft) and Bighorn Peak. The hike begins on the popular Icehouse Canyon trail but soon moves off to the much less traveled Ontario Peak Trail, where you might see more bighorn sheep than people. The Ontario Peak Trail roughly follows a ridge line, offering great views culminating in the “rock nest” summit of Ontario Peak. There’s also a short spur trip to Bighorn Peak, because, why not? This is a tough hike but worth the effort–one of my favorites.
How To Get To the Ontario Peak Hike
Use this GPS trailhead address: 20 Ice House Canyon Rd, Mt Baldy, CA, 91759, USA.
There is a big parking lot, but it fills up by 7am, and you need a parking pass. I use the affordable National Parks Pass, which gets me in every park, 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.
You need a permit to hike in the Cucamonga Wilderness, and it’s easy and free. A box at the trailhead has permit forms for you to fill out. Bring a pen. If there are no forms, fill out your info on a piece of paper and leave it.
Gear for the Hike
This is a long and challenging hike. Make sure you pack plenty of water, snacks, and layers. In the winter, there can be snow and ice. Check this summit weather and call the ranger office for the latest conditions and don’t take any risks. This is not a hike to do when there is snow or ice.
If you want to check if there’s snow on your hike, read this guide.
I try a lot of hiking boots and shoes, and there are some great options out there, but the La Sportiva Spire is the best combination of comfort, protection, low-weight, and durability. They are waterproof, and the high cuff keeps debris out without the need for a gaiter. Time tested over thousands of miles. Use them with a two-layer sock system to end blisters for good.
Reviews & Lowest Prices: Women – Men
On a medium or longer hike I recommend a pack like the Osprey Talon 33 (men) or Osprey Sirrus 36 (women) which is a little bit larger. These packs are on the upper end of the (35L) daypack range, but they only weigh a small fraction more than a pack with less capacity. Having the extra space gives you more flexibility and means you don’t have to jam things in there. I use the space for things like extra layers in the winter, extra water on desert hikes, and even a tent & sleeping bag on overnights.
If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Mini fits in your palm and weighs next to nothing.
