This trail actually came out to be closer to 4ish miles and the elevation gain was really not bad! The trail to the cabins/ruins is packed, you could probably even get by without added traction but it did help me (microspikes)! After the cabins I'd recommend snowshoes/skis as it's not packed, I tried to get up to the mining stuff and post-holed the whole time so I turned around. Beautiful views of the mountains both in front and behind, a really good sized parking lot (it does come up on you kind of fast so be prepared!) with no facilities but definitely a great hike! I'd love to see it in summer with no snow too!
