Planning Your Hike to Castle Rock
Getting There & Parking
The Castle Rock Trailhead is conveniently situated on the south side of Big Bear Lake, making it a readily accessible natural escape. To pinpoint your journey, use the address: Castle Rock Trail 1W03, Big Bear Blvd, Big Bear Lake, CA 92315.
Parking near the Castle Rock Trailhead can be one of the trickiest aspects of this popular hike. The primary parking area is a small lot located approximately 0.25 miles east of the trailhead itself. Spaces here are limited, and it’s advisable to arrive early, especially on weekends or during peak season, to secure a spot.

If the main lot is full, alternative parking can be found, though still limited. About 150 feet to the west of the trailhead, a small shoulder along the road provides space for a few vehicles to park. This area is less formal but often utilized when the main lot is at capacity.
Roadside shoulder parking west of Castle Rock Trail entrance
Further west, about 0.25 miles from the trailhead, another small shoulder offers additional parking possibilities. While slightly further away, this option can be useful when other spots are taken.

A crucial safety note regarding parking for Castle Rock Trail: all parking locations require a walk along Big Bear Boulevard to reach the trailhead. This road can be busy, and vehicles often navigate the sharp turns at considerable speed. Exercise extreme caution while walking along the roadside. It’s vital to stay as far to the side as possible, remain alert, and assume you are not visible to drivers. Defensive walking is key to safely reaching the trail entrance.

Once you’ve navigated the roadside walk, the Castle Rock Trailhead will be located just off the road, on the mountainside away from the lake.
Essential Gear for Castle Rock Trail
Given that the Castle Rock Trail is relatively short and not overly strenuous, specialized gear is not essential. Comfortable fitness or light hiking attire is perfectly suitable. However, carrying water is highly recommended, particularly during warmer months, as the uphill climb can be demanding. Aim to bring at least 1 liter of water, especially if you plan to extend your hike to Bluff Lake.
For footwear, sturdy hiking shoes or trail runners are advisable to provide good traction on the sometimes loose and rocky terrain. While not mandatory, trekking poles can be beneficial for those who prefer extra stability on steep inclines.
It’s important to note that during winter, the Castle Rock Trail transforms into a challenging icy and snowy path, often becoming unsafe to hike due to its steepness. The ideal seasons to fully enjoy this trail are spring, summer, and fall when the conditions are more favorable.

Navigating the Trail: Maps & Markers
Stone bin trail marker on the Castle Rock Trail
A distinctive feature of the Castle Rock Trail is its unique trail markers: wire bins filled with rocks, often referred to as cairns. These stone bins serve as your primary guide as you ascend towards Castle Rock. Staying on the official path is straightforward as long as you keep an eye out for these markers; you should typically spot one every few minutes. If you find yourself walking for longer without seeing a marker, it’s a good indication you’ve veered off course.
Due to its popularity and short length, numerous unofficial paths and shortcuts have developed along the Castle Rock Trail. It’s crucial to disregard these and consistently follow the official trail marked by the stone bins. Some maps might incorrectly depict trails branching off; always prioritize the physical stone markers on the ground to stay on the intended route to Castle Rock.
