An excellent Bighorn hike, wonderful scenery. It's a climb but you barely feel it, so easily done for a day hike but you can also camp by the Lost Twin Lakes. The lakes are stunning, an amazing turquoise color.

Amazing place right at timberline. Georgeous lakes with very LARGE trout. I was the only person there. Caught several golden and cutthroat trout all over 16-18 inches. Moderately strenuous hike to get there from West Tensleep lake. Took right at three and a half hours. Got frost that night and it snowed on me on the way out. ALWAYS take cold weather gear to this place. Highly recommended. Good camping at southwest end of lower lake.

Gorgeous hike, as always. Never hiked it this early in the year though - beware of the 2 "stream" crossings. They were no problem to cross in the morning on the way up to the lakes, but by the time we wanted to return in mid-afternoon, both had turned into uncrossable raging torrents. We managed to swim across the first one (water well over our heads, ice cold and FAST) but the second one was not possible. Fortunately we had good weather and were able to dry our stuff out over a fire near the second crossing while we waited for morning and the water to drop. Probably best to do this one as an overnighter early in the season so you can plan to be trapped on the far side of the rivers! Well worth it though. Stunning scenery that does not reveal itself to you all in one go...

According to my GPS, the trail is actually 12 miles; 6 into Lost Twin, about 3 into Mirror. The trail was GORGEOUS. The first mile is misleading, however, as it's fairly easy. The last two miles into Mirror are pretty tough. The trail from Mirror to Lost Twin Lakes is nicely marked, but again, it's a climb. Be prepared for the elevation. The view from Lost Twin was worth every drop of sweat, though. Absolutely gorgeous. We did this hike as an overnighter, with base camp at Mirror so we could day-hike into Lost Twin.

Moderate, not so much of a difficult trail. The only trouble you MIGHT have is the light boulder field on the approach to the second lake, but there are clear ways around that. We hiked to the top of the cliff above the lakes (almost 2 hours up) for a pretty spectacular view and great accomplishment. Do be prepared for storms and hail (late afternoon thunderstorms are always a threat) There was a nice camping spot on the western ridge above mirror lake, we split it in to a Very casual stroll and a 2 night trip. We saw lots of very tame deer in meadows and about 10 horses came up the trail

This is one of the premier hikes for the Big Horn Mountains - a must do, if you want to experience the best the mountains have to offer. The trail starts easy through a very old lodgepole timber stand. It evolves into a steep climb (a good cardio work-out) up a ridge raised by two opposing glaciers. The top of the ridge gives you great views of the upper alpine area, as well as the ascending valley. About half way up the valley is Mirror Lake. Today it was an intense blue and smooth, affording wonderful photo opportunities with the reflection of the rocks and trees in the lake. There is a slow easy climb up a stunning creek valley, with lots of meandering streams, wildflowers, and moose. This opens to a meadow, where you can see the massive granite cliffs that surround the Lost Twin Lakes. The climb up that final ridge (we called it "Heartbreak Ridge" ) is tough, due to the elevation, but once you crest it, the view of the first lake is stunning. There is no trail to the second lake, just a hard boulder climb, but the second lake is the most rewarding of all. There are 14-18" cutthroat trout there and - surprise! - a sandy beach! Take foul weather gear - a hail storm caught us by surprise on the top of the cliff - very cold and slippery.

Although I've done other forms of primitive camping, etc., this was my first backpacking trip. Wow. Beautiful trail - streams, meadows, wildflowers and more. Bring a camera! It's worth the extra weight. However, I'd also bring cold weather gear (fortunately I did.) We camped near the lakes and woke up to at least 3 inches of snow, with more on the way. Also, the trail itself was very challenging, especially for those of us who are beginners. It was still very enjoyable.

Mirror and Lost lakes are accessed from the West Tensleep camping area, which is also the location of the Mistymoon trailhead. This trail offers decent access to the Bighorn High-country via a fairly well maintained trail. Snow does remain in the High country well into June and the trail stays fairly muddy for some time. Crossing Tensleep creek can be a little difficult during heavy runoff and melting as well. Later in the Summer the Creek is but a trickle and the trail is dry as a bone. Always bare in mind that this (and many Bighorn trails) is a multi-use trail and pack animals are often encountered on route. It is alway best to step off the trail and allow them the right away. Bighorn Peak can be summited from the Lost Twin lakes where one can enjoy the majestic views of towering cliffs. Mid-July is an excellent time to visit this area of the Bighorns as the alpine flowers seem to be at a peak. Wildlife abounds around this trail and elk, moose, pika, marmots and deer are often seen along the way. THere are a few mosquitoes beside the lakes during the summer but they are usually tolerable.
