The Donner Lake Rim Trail around Truckee is a serious hiker’s destination, with 15 miles of trail currently open and ambitious plans to eventually loop 23 miles through the high country surrounding the lake. Dogs are welcome on the full network, though you’ll want to know that nine miles allow bicycles while the six-mile segment shared with the Pacific Crest Trail is foot traffic only — a nice stretch if you’re looking for quieter hiking with your dog.

Johnson Canyon is worth your attention even though it sits practically in the shadow of Interstate 80. Most people skip it, which is exactly why it feels like a real find. The canyon has shady pockets throughout, aspen groves that are especially nice in fall, and decent wildlife watching opportunities. The trailhead starts at Wendin Way, just past a gate about 100 feet from where you’ll see the Donner Lake Rim Trail signboard near the Donner Lake Interchange.

From Wendin Way, expect a gentle climb for roughly the first mile and a half until you hit the junction with the main rim trail. Once you’re there, you get to choose your own adventure. Going right means tackling a serious set of switchbacks up to Donner Ridge — the views from the top are genuinely worth the work. Heading left takes you through more open terrain with wide-open vistas, and if you continue that direction you’re looking at around 3.5 miles to Summit Lake. Both options work beautifully with dogs.

Plan to carry all the water you’ll need since there’s nothing along the way. Bring extra for your dog, especially on warmer days. The elevation means it can feel hotter than you’d expect, and your dog will appreciate having regular water breaks. Pack out everything you pack in — the trail gets heavy use and these high country areas are fragile. The Rim Trail is worth dedicating a full day to, whether you go for the ambitious mileage or keep it shorter and sweeter with Johnson Canyon.
