Drive 3.9 miles past the entrance booth of Mill Creek and park there at the end of the plowed road. You’ll follow the Forest Service groomed trail to the Big Water trailhead/yurt. Continue on for another couple miles to 8600’ into the upper watershed of Mill Creek Canyon with views of the Park City and Parley’s ridgelines. Avalanches are infrequent, though sometimes occur into the Thousand Springs area halfway to the yurt area. Dogs are allowed in Mill Creek with alternating on/off leash days – check with the Forest Service for recent policy/schedules. The Forest Service charges a nominal day fee for canyon recreation. Season passes are also sold.
