I have done the mirror lake trail a number of times in the summer super rewarding at the lake.

been there many times. I always enjoy the varying terrain and scenery.

Hike is easy for the first 3-4 miles and quite strenuous for the remaining few. Rocky, steep sections prove difficult, but the high mountain terrain, striking views, and fly fishing make the trip more than worth it.

The loop is a great two night hike with high alpine views and fishing. Follow 407 to junction of 410 and 401. 410 is considerably shorter but staying on either will complete loop; be ready for a climb either way. I recommend staying first night a Upper Falls Creek Lake or Jerome Rock Lake. From there make your way to Big Brother Lake for the second night. One thing to watch for is the junction of trails 409 and 401, a little less than a mile before Big Brother. The intersection is marked by a post but make sure you are looking for cairns. Once at this intersection look for cairn to north (401) and one to east (409). Great small wilderness with a lot of options; definitely a yearly destination for me.

Great area with lots of options. Most of the lakes have great fishing and camping but they get a lot of use. "The Blaze" is a long strip of snow on Blaze mountain, that sticks around all year for those wishing for some summer turns.

This is an awesome area. There is camping at the trail head, not a lot of sites but several. This area is used by a lot of horsemen and Backcountry Horsemen of Bozeman have taken on the responsibility to clear this trail and they spend most of their weekends working on trails in this area. There is a Forest Service cabin you can rent at the trailhead also. The trails are very well marked and there are trails for every hiking ability and age. I have seen families up there with young kids to grandparents. The only reason I do not give this a five star is I do not like to be in areas this crowded. There are lots of lakes and fishing opportunities.

ABSOLUTELY AMAZING!! I've seen things on this trip that I've never seen in my life... the terrain is tough, and you need to side step the pack hourse manure along the way, but worth every second of it. Take your time crossing the snow pack trails and scree feilds and take the time to do some fishing at Thomas and Mirror Lake. Must see Mirror Lake in the morning for best results. Check to be sure all trails are open if you can - avalanche going up to Indian Ridge from Thomas Lake cost us another 5miles.
