Snow Peak Mill City Trail is a 6.4 mile out and back trail located near Gates, OR that offers scenic views. The trail is rated as difficult and primarily used for hiking.
Attempted this hike yesterday but there was a locked gate 8 miles before the trail head. Phone reception is poor in this area and I was unable to search for a potential different route. This may be a great hike if you could get to it. There may be other options but do your homework.
