I did this in reverse on 4/10, starting at Sunrise Trailhead ending at Lost Dog Wash (need a ride or second car to do this obviously). This direction started with a bug incline and ended with a nice traverse downhill. Stopped for a snack at Sunrise Peak (beautiful shade spot) and was joined by a hummingbird and a few lizards. The trail is pretty rocky so be aware, I'm a flip flop hiker and it wasn't too bad but this was rockier than most of the Gateway Trailhead trails.
