Get Directions →Trail Description
Castle Rock Trail stands as one of Big Bear Lake's most beloved hiking destinations, offering spectacular panoramic views of the lake and surrounding mountains from its dramatic granite rock outcropping. Located just 1.1 miles east of Big Bear Dam on Highway 18, this moderately challenging trail attracts hikers year-round with its impressive geological formations and rewarding summit views. The trail climbs steadily through the first half mile, gaining most of its 500-foot elevation through mature Jeffrey pine and white fir forest. Stone cairns mark the route, though the trail can become confusing near the top with multiple splits - downloading a trail map to your phone is highly recommended. The final approach to Castle Rock requires some light scrambling over boulders, but the effort is rewarded with breathtaking 360-degree vistas of Big Bear Lake, the San Bernardino Mountains, and on clear days, views extending to the Mojave Desert. This is Big Bear's most popular trail, so arriving early (before 9am on weekends) ensures easier parking and a less crowded experience. The new Castle Rock Trailhead Parking Lot at Big Bear Blvd & Talbot Dr now offers free parking with restrooms and bike racks. Dogs are welcome on leash, though they cannot navigate the final boulder scramble to the very top of the rock. For experienced hikers, the trail continues beyond Castle Rock for another mile to connect with Bluff Lake Reserve, adding a beautiful extension through pine forest.
