Trail to the top is actually only 7 miles out and back. There are some other paths once you reach the mountain lake, but that is where the main trail ends.
Hiked it in the middle of October with no problems. A dusting of snow here and there, but nothing to slow you down. View at the top is totally worth it. Saw plenty of bear droppings so make sure to hike with bear spray at least.
Very fun hike! Did it last weekend (6/4/16) and towards the top had to make through deep snow in some parts. Mildly inconvenient (just bring extra socks!) but still fun! The lake was absolutely beautiful. Couldn't make it to the plane wreckage due to snow, but will definitely do this hike again! In my opinion it was the perfect length for a day hike. Not overly long but you definitely feel like you worked for the awesome views!
Easy trail. Took my kids they did well. About 2.5 miles in had to turn around due to log build up on trail. Could go around if we wanted to walk through thorn bushes, my kids were not done for that. Trail is not maintained regularly. Also spoke with the home owner of the house on trailhead. Says the hot spring is a one person two people max hot spring.
This was such a wonderful hike. Backpacked into the lake and stayed the night on 8/11, and loved it. The hike is rated at moderate, but I'd say the first 2.5 miles are easy, and the last 1.5 miles is easy with moderate sections. The lake itself is beautiful, and has a great population of brook trout that will bite any lure that provides action. I noticed they will not bite anything sitting idle though, so cast and reel, cast and reel. If you plan on camping, hit the far end of the left side of the lake, there is an excellent large camp spot with fire ring thats tucked into a nice copse of pines. This camp spot is also only a few hundred yards from the open grassy area that has the remnants of the 1959 plane crash, which is worth checking out. Definitely a hike I intend to do again, and would be the hike I chose if I was introducing a friend to backpacking, as the easy hike, great scenery, and great fishing make it a perfect introductory backpacking trip.
Great day hike or overnight stay, beware of creek crossing right at trailhead, steady climb to lakes and very well defined trail. Would rate this trail as moderate in difficulty. Nice views and great fishing. Currently road is open for motorcycles, mountain bikes, or hiking!
Fun, kinda long, some steep parts, but great! It wasn't too hard, though, because my great grandma and little sister both made it up. Once we got to the lake, we fished, ate lunch, and had a good time. There are fire rings on the eastern side of the lake, inside the trees. It would be fun to backpack up there with a tent and stay overnight. There is actually some really cool WW2 plane wreckage outside the lake that was fun to look at.
This hot springs is back by Potosi campground. I hiked the trail at midnight a few days ago (end of May). The trail was easy to follow and pretty easy, I'm sure very easy in the daylight. It was amazing at night. We had the spring to ourselves and sat in the dark with a crystal clear night sky. Amazing star gazing opportunity. If you don't have a vehicle with access to cross the creek, you'll have to walk across. We did this late at night and it was pretty cold, but manageable. Be careful! Also, you are in MT, bring some bear spray.
