Castle Rock Trail
Time Out says
If you embark on one hike in Big Bear, let it be this moderate but approachable trail. The dog-friendly forest hike is no more than a couple of miles round-trip, but the first half-mile involves a 500-foot elevation gain. Put in the effort and you’ll be rewarded with sparkly views of the lake. The trailhead is located right along the highway; look for a limited number of parking spots just east in a turnout on the north side of the road.
