I did this back in mid-July. Outstanding hike, saw four bull moose. Heads up, if you’re driving from the east (like from Buffalo), Google Maps might route you on a dirt road that is not the right way. (It’s an ATV road past a little campground that quickly turns rocky and atrocious and gated anyway after a harrowing stretch). Instead, keep going on the main paved road until it’s unambiguously the correct turnoff for West Tensleep Lake. Then it’ll be about 6 or so miles on a graded dirt road, totally fine.

The hike has elevation changes but nothing too steep. The high altitude makes it seem worse than it is. The trail takes you through forest, river beds, and alpine meadows - eventually ending at a lake. I was not too impressed with the lake, but I did just come from Yellowstone and the Grand Tetons. The trail was a bit hard to follow, especially at the end. The trail starts out wide and well-maintained, following the signs for Trail 65 at the major splits. It then gets narrower and narrower. By the end, the trail branches out into several ‘deer paths’ that lead to the lake (no unambiguous main trail). The AllTrails route is definitely wrong in several sections along the final mile. I tried to take it on the way back on a ‘sort-of’ trail but was cutting through brush and dead ending in a marsh several times. I eventually fought my way back to the best-looking trail I saw on the way up, and the going was much smoother. There were no bugs, but I also didn’t see any moose. The drive in was over a slightly bumpy dirt road. 4WD not required, but you won’t be driving very fast for ~6 miles. The parking lot was fairly big, and was mostly full when I arrived around 11:30.

Great hike, saw a lot of moose so be careful and aware of your surroundings. A couple trees fell near the first mile of the trail so that may require some jumping and climbing and whatnot

Pretty difficult and long hike for us out of shape flatlanders, but the views were definitely worth it! The trail is rocky, but well established all the way up to the Lost Twin Lakes. We ended up walking past Mirror Lake, as there is no sign for it and it’s not very visible from the trail. We left around 9:30 and got back a little before 6. We spent a couple hours at the lower Lost Twin Lake fishing and caught quite a few cutthroat trout! It was absolutely beautiful up there, one of the best hikes I’ve done in the area.

This was an absolutely spectacular hike where you passed nearly every scenery you would want walking through the forest, valleys, meadows with streams, ridges and up to an Alpine Lake. We only saw a couple other groups of people. It ended up being closer to 13 mi but that may be because we went a little off path. A perfectly challenging hike for novice to moderate hikers.

One of the best trails in the area! It does have some climbs. I saw maybe two mosquitos the whole time, which is amazing! Although i would always still wear bug spray. Took us 3 hrs to get there. I highly recommend going to the upper lake as well as the lower. Our mileage was 12.3 miles total. Left the parking lot at 10:30am and got back at 5pm.

I did this trail with my 59 year old mom. It was a gorgeous day. You turn down west ten sleep road (next to deer haven) and drive all the way to the end. It was trail 65. It took us 3 hours to get there with a couple breaks for a snack and water. Left the trailhead at 8 am. We ate lunch at the lake and took a little dip in the lake to ice our sore legs. The hike back was significantly easier. It started to rain and hail on us, so it slowed us down a little bit since it was muddy and the rocks were slick. Got back in 2.5 hours. Our feet got a teeny bit wet (bring extra socks just in case) on the creek crossings. Overall it was a beautiful hike that I highly recommend.

The trail is very straight forward and easy to follow. Highly recommend stopping at Mirror Lake which is about halfway up. Once you get to Lost Twin Lakes, the path splits and you can keep going up or you can go to the shore of the first lake. I recommend going left and up which will take you over a ridge and over to the second lake, which has less traffic and better views (in my opinion). There’s great fishing over there. Mosquitos are bad in the evenings. Super fun trip, great one night backpacking trip!

When you get to the trailhead you will see a sign. To get to Mirror and Lost Twin lakes take trail 65. For some strange reason, the lakes aren't on the trailhead map nor other maps I reviewed. I finished this trail on July 10, 2020. If you don't bring water bring a Life Straw and drink on the way. Be careful on river crossings. Some rocks are wobblers. Great camping location on the west side of Mirror lake. It isn't unrealistic to walk past Mirror lake. When you cross the river on a rock "bridge" which is pretty obvious you are within a hundred yards of Mirror lake, but you must exit the trail toward the northeast over a little rise to find it. If you don't have bug spray and sun block you will regret it.

Awesome trip. If going to camp at Twin lakes, get protective nets. No Bugg repellent works.... tried 3, none works.

Started at 715am. snow covering the whole way out, dried up but a little wet on the way back. Lost the trail down the boggy area, but you can figure it out with the map. Just aim for big rock face, just be ready to get a little dirty. The Lake and the 2 moose we saw made the hike worth it.

Great little hike in to the falls. quick little breather and a few switch backs and it pretty much a cake walk to mirror and lost twin. awesome fishing at both places and the bugs were really not a bother. pretty cool over night trip.

This is national forest trail 65, I wish All Trails listed it. The trail is defiantly over 10, I had 12.5 but I did lose the trail for about 15 mins. I think getting down to the shore of Twin lakes isn't accounted for, maybe that's where the extra milage comes in. There was one point where the trail didn't match up with the app, hence me losing the trail for a bit, and of course there happened to be a game trail that tempted me into a meadow where I lost the real trail. The trail is fairly well maintained, there are some steep rocky areas that I was glad for my poles but I didn't need them for most of the trail.

Nice trail. My experience was that if you follow the map “trail” into Elk Park, there isn’t a trail and it was a lot of bouldering and off trail navigation. I kept trying to find the “trail” but besides a few karens, there wasn’t much of one. That was certainly a tough way to go but I did enjoy it. Once I got on trail 065 (the easier alternate route to Mirror Lake) it was more chill. Lost twin lakes were amazing and I chose to off trail it all around there and it was great! Several moose and an elk in Elk Park, so fitting! Great short trail and camping off of Mirror lake was busier but a ways off the lake it was very still and quiet both nights. I did hear elk calling throughout the night, way cool great weather all around!!!

Great trail for a beginner backpacking trip. Me and two friends hiked to the lost twin lakes in under 4 hours. After fishing at the lost twin lakes and catching amazing alpine cutthroats we hiked back down to camp in the grass basin under the lakes. We slept about 30 feet from a mother moose and calf the entire night. Great alternative hike from west ten sleep trailhead if Mistymoon is a bit to much for you. The view at the top is amazing cliffs dropping into the lakes

Amazing hike! I cannot recommend it highly enough. Amazing views and we saw so much wildlife. We left the trailhead at 10am and got to the lake at 1pm without rushing. We had lunch, walked around the first lake and went for a swim (very cold!!). We spent about 2 hours up by the lake and got back to the car by 5.30pm. Do it!

Got to the trailhead about 6am, highly recommend doing this hike early. Watching the sun come up made this about as good as it gets. 2 crossings where my boots got a little wet but very manageable. The lake had tons of mosquitoes so if you’re planning on staying up top a while bring big spray. Overall very beautiful trail.

Wow. Everything you could want in a hike. Made this in a day. Taking my time, I went out and back in about 8 hours. Eating lunch at the lakes. Ran into several moose. Waterfalls were running strong. With bug spray, bugs completely leave you alone. Highly recommend!

Great trail. One day out and back on July 11, 2019. Two minor creek crossings that were easy with extra shoes. The trail out & back is more like 12-13 miles depending on how much you get off of it to explore. This trail has it all: forest, lakes, creeks, waterfalls, elevation, plenty of water to filter, great views, good fishing, easy to follow trail, and very few people! Check out a video of the hike on YouTube at Nolan Ventures.
