Castle Rock Trail at Big Bear Lake is a dog-friendly trail located in the San Bernardino Mountains of California. This trail, spanning approximately 2.5 miles roundtrip, presents a moderate-level hike with an elevation gain of 500 feet.

Though the trail is short, it does include some rocky sections and steep inclines. There are plenty of clear trail markers and a couple of benches where you can take a break along the way. Hikers have observed rattlesnakes in the area so make sure to stay on the trail, keep your dogs close, and watch out for them.

The path takes you through dense pine forests, rocky terrains, and views of Big Bear Lake from the top of the trail. The highlight of the hike is reaching Castle Rock itself, a large granite outcrop offering panoramic views of the lake and the vast mountain ranges.

Being a popular trail, Castle Rock Trail can attract a moderate crowd, especially during weekends and holidays. For a quieter experience, consider hiking on weekdays or early mornings to avoid peak times.

Parking for Castle Rock Trail is available at the designated trailhead, but it can fill up quickly, especially during peak seasons. There are also spots on the side of the road where you can park your car closer to the trailhead. Arriving early or avoiding peak hours is recommended to secure a parking spot.

This trail is only a 2-minute drive from Boulder Bay Park so it’s a good spot to visit before or after you take your dog swimming near the park.

The trail was well-marked. Steep inclines with beautiful lake view at the top. Rattlesnakes were spotted but away from the trail. Be careful!
