Grays Peak Trail is a dog-friendly hiking trail near Fawnskin in the San Bernardino National Forest above Big Bear Lake. The trailhead sits at a solid elevation, so you’ll feel the altitude right away, but the moderate out-and-back route is manageable for most dogs in decent hiking shape. Once you get going, the path winds through dense pine and fir forest that stays cool even on warm days, which your dog will appreciate.

The real payoff comes at the higher elevations where the trees open up and you get those panoramic views of Big Bear Lake sprawling out below you, ringed by surrounding mountain peaks. On clear days it’s genuinely impressive—the kind of vista that makes the climb feel worth it. Spring brings wildflowers along the trail itself, adding some color to the forest walk. The whole year has that crisp mountain air that feels completely different from lower elevations.

The trail gets steady use, which means it’s well-maintained, but also that you’ll encounter other hikers and dogs. Keeping your dog on a leash is essential, both for their safety and out of respect for others on the trail. The footing can be rocky in sections, so watch your dog’s paws, especially if they’re not used to sustained hiking. Bring plenty of water—dehydration happens faster at elevation, and your dog can’t tell you when they’re thirsty until it’s become a problem.

The 4.7-star rating from nearly a hundred reviews suggests most people find it worth the drive up from the valley. It’s the kind of hike where you’re not fighting crowds, but you’re also not completely alone on the trail. Plan for a few hours round trip depending on your dog’s pace and how long you want to spend at the top taking in the views.
