The Grout Bay Loop at Big Bear Lake is a 13-mile intermediate-level bike trail that works well for riders who want a mix of challenge and manageable terrain. You can access the trailhead from the parking area near Fawnskin Fire Station heading toward 3N14, or start from Hanna Flat campground if you’re already camped there. The ride takes you through varied landscape — dense forest sections that offer good shade, then opens up to views of the lake and surrounding mountains. It’s the kind of trail where you’ll actually notice the elevation and the altitude, so don’t expect a casual ride even though it’s marked intermediate.

Dogs handle this trail reasonably well if they’re used to longer outings. The packed dirt surface is easier on paws than rocky terrain, and there’s enough forest cover that your dog won’t overheat on warmer days. You’ll see other people with dogs out here, so it’s clearly a common choice for riders who want their dogs along. Just plan for water — while there are some streams in the area, bringing extra for both you and your dog makes sense, especially on the sections that are more exposed.

The trail loops around the bay, so you’re never too far from water views, which breaks up the monotony of pedaling. Fall and spring are the best times to ride it. Summer afternoons get warm, and winter can mean muddy patches depending on recent rain. The Big Bear Lake website has current trail conditions if you’re planning a specific trip, which is worth checking since weather up here changes pretty quickly. Parking at the trailhead can fill up on weekends, so arriving early helps if you’re planning a weekend ride.
