Bertha Peak via Cougar Crest Trail

Trail Description

Bertha Peak stands as one of Big Bear's premier summit hikes, offering unparalleled 360-degree views of Big Bear Lake, the Mojave Desert, and the San Gorgonio Wilderness from its 8,201-foot summit. This moderately challenging hike begins on the popular Cougar Crest Trail, following its well-maintained switchbacks through pine and fir forest for 2.4 miles until reaching the Pacific Crest Trail junction. From there, turn left (east) on the PCT and continue for another 0.75 miles through beautiful high-altitude forest. Watch carefully for the Bertha Peak spur trail on your left - it's marked but easy to miss. The final push to the summit gains about 400 feet in 0.6 miles, with the last section becoming quite steep as you scramble up the rocky slope. The effort is absolutely worth it: the summit offers one of the finest panoramas in the San Bernardino Mountains. On clear days, you can see Big Bear Lake shimmering below, the snow-capped peak of San Gorgonio to the west, the vast Mojave Desert spreading to the north, and on exceptionally clear days, even the Salton Sea to the southeast. The summit area features interesting rock formations perfect for photos, and provides a wonderful spot for a lunch break while soaking in the views. The peak is named after Bertha Gilkey, an early 20th-century conservationist and member of the Sierra Club. Because this trail starts at over 7,000 feet and climbs to over 8,200 feet, altitude can affect some hikers - take your time, stay hydrated, and listen to your body. The trail is exposed in several sections, so sun protection is essential. This hike combines the best elements of Big Bear hiking: forest beauty, physical challenge, and rewarding summit views.
