Nature tripsGreat!No shade

THERE ARE NO TRAIL SIGNS. TAKE THE TRAIL FROM THE BACK OF FIRST CAMPGROUND HEADED EAST. According to a smart watch in out group the trail to the hotsprings is only 0.98 miles and we only changed 88 feet in elevation. In other words, it was a lovely meander through some Montana landscape, a bit of which was mountain field scape. The hotsprings itself is mostly self kept, meaning it might be grungier than some people are willing to swim in. The water does not cycle in/out quickly enough to rinse out the silt that bubbles up with the hot water. There was also some hair floating around as well. I give it a banging review tho because we had a fabulous time and despite the slightly squeamish factors in the water, if you truly expect anything better from a self kept mountainous hotspring then just forgo this location. Instead, you might instead appreciate Norris Hotsprings really close by.

The trail itself isn’t too interesting, but the hot spring is cool! Not a whole lot of room though, can fit about 5 ppl comfortably. We extended the trail beyond the springs to get a higher up view.

Anyone that complains about a place like this has absolutely no business being there, or really anywhere in Montana. If you’re worried about a bit of mud go pay $20+ at Bozeman hot springs. It’s a short and easy walk, and the water is a very nice temperature. Enjoy!

Very cool little hole in the earth hot springs :) it’s close to a very busy campground so expect to spend it with a few other people but the drive back into it is beautiful and the hike to the hot springs is simple and pretty. There’s also lots of surrounding lakes and other hikes to do in the area if you stay for a weekend. Water was a perfect temperature.

The hike for this hot springs was super chill and easy. We even saw a moose by the river as we walked over during the day time. The hit spring felt super nice and the stars were amazing during the evening. Definitely a place to go back to

Blowdown

There was a large tree that had fallen on the path, but it is in a flat area so walking around it was easy enough. Other then that the event was easy and pleasant.

Nice little hike. Not a super hot spring but still refreshing. Make sure to take trail from the first camp ground.

Nice and quiet. A beautiful overnighter, only a couple other people at the campground and we had the hot springs to ourselves!

Easy to follow trail but really muddy hot springs. Great view but no water flow and mild hot temperature. Would call this “Mudpots”.

The hike itself is flat and runs along private property for about half of it. The hot spring is more of a warm spring and had broken glass in it. You will leave feeling like you need a shower stat! We blogged about it if anyone is interested in reading more: https://practicalvagabonds.com/upper-potosi-hot-spring/

We came in late at night. There are two entrances, the first one leads to open space for bigger RV's, parking for day hikers, and the road to one side of the campground. The second entrance is to more campsites along the creek, where we ended up moving to the next morning. This place is beautiful!! We followed a trail along the creek for a bit that was a quick easy hike. There is another hike, 303(?), across the main road that leads up 900 ft to a vista of the valley according to the camphost. The hot springs are an easy hike about a mile. We went twice, once in the afternoon which had more people in and out, and in the morning with just us. We spent some "au natural" time in the springs. The temps are not extremely hot more like a bath or hot tub at best. We thoroughly enjoyed the springs! The main road leads back to more marked campsites and a fork pointing to Bell Lake or Granite Lake. We went up towards Granite Lake. The road is rough and slow going and we never did reach the lake after taking a side road and coming to a field to turn around. We did see an ATV going up the road presumably to the lake. I recommend this campground and hot springs!

Cute underrated spring. Very easy hike and just a little ways down a very well maintained dirt road. You park along a fence on the far end of the campground a cross a little log bridge to the trailhead.

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.
