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.
