    Route Description for Hanna Flat Campground Trail

    Although there isn’t an overly large amount of elevation gain along the Hanna Flat Campground Trail, it is still a challenging hike that features some rugged terrain. Be sure to wear proper hiking boots with good support in order to have the best footing along the trail. Additionally, access to this trail does require an adventure pass, so be sure to purchase one prior to setting out on your hike or else you will be fined.

    Whether you are planning for a fun weekend of camping or are simply looking for a solid day hike, the Hanna Flat Campground Trail will be sure to provide you with hours of fun. A pleasant forest setting, undulating mountain terrain, and scenic views overlooking Big Bear Lake await on this great outdoor adventure in San Bernardino National Forest.

    Setting out from the Gray’s Peak Trailhead on CA-38, follow the trail as it leads uphill through the forest to the northwest for 1.2 km, passing by the Yellow Post #1 campsite to arrive at a junction with Forest Road 2N70. Here, you will turn right and keep right for the next 0.7 km, where you will find a path branching off into the forest on your right.

    Taking this path, you will traverse a rocky stretch of woodland terrain for 1.2 km and meet back up with the road, following it to the right. Here, you will quickly arrive at a junction and take the path on the left, where you will immediately be met with a fork. Keep right here and continue along the trail as it bends to the northwest through the dense cover of the forest.

    After 1.2 km, you will cross directly over the road and pick up the trail on the opposite side, keeping left for another 1.8 km to pass by the Yellow Post #2 campsite and meet up with a road. Once again crossing over to the opposite side, you will traverse the rocky landscape to the north for another 0.9 km. Here, you will cross over yet another road and pick up the trail that will take you past the Hanna Flat Big Bear Lake Lookout.

    After a quick climb up the rocks to take in the views stretching south to Big Bear Lake, you will follow the trail as it descends slightly to the northeast to arrive at the endpoint of the route at the Hanna Flat Campground. If you are planning on camping overnight you can begin to set up camp, otherwise, simply head back along the same route to return to the starting point of the Hanna Flat Campground Trail.
