A gorgeous way to experience the foothills of the eastern Sierras. Mosquito Flat Trailhead (aka Rock Creek hike, Little Lakes Valley hike, and others depending on who you ask) is a relatively flat and easy, out and back hike through enticing scenery regardless of the season - everything from peaceful brooks to lake after expansive lake to snow-laced (or snow capped depending on the time of year) craggy mountain peaks. Depending on when you want to turn around, assuming you want to get some good lake vistas in, you can make this anywhere from a 2 mile round trip to definitely over 6-7 miles rounds trip.
From the 395 turn west towards the Sierras off of Rock Creek road, an off ramp about 15 minute south of Crowley Lake. This road dead ends after about 10 miles into a parking lot that fills up fast - at 8:30am on a Thursday it was completely full; we literally took the very last spot. But, there is a ton of overflow parking - you'll just have to walk a ways more to get to the trailhead. Despite the abundance of cars, this has nowhere near the popularity of, say, a Yosemite Valley floor hike, and if you start early you'll only see fellow hikers here and there.
From the trailhead we went straight in, just to the right of the main map at the beginning. We took a fork early on to Morgan Pass (the other option is Mono Pass, which is a less lake-y trail), which'll take you directly through Little Lakes Valley. Pictures speak for themselves, but essentially you'll comes across several lakes in quick succession, each lake with its own unique blue and green hues and cathedral-like granite faces rising out of the water. Each lake has its own characteristics and special turnouts for a different view - despite an abundance of lakes back to back there is no way you could get bored with the variety of vantage points and perspectives.
Continue on this main, well-demarcated path for a ways, and you'll pass Mack Lake, Heart Lake, Box Lake, and Long Lake, and eventually you'll see a turn off for Chickenfoot lake - would highly recommend taking this turnout, which leads down another 1/4 mile path or so to Chickenfoot. All of these lakes are serenely stunning, but if you want to go a little further...
Once back on the main trail from the Chickenfoot hike, continue up the small hill (to your right when looking at the Chickenfoot sign from the main path) and head towards Gem Lakes. Interestingly, we saw far fewer hikers after Chickenfoot, making me think Chickenfoot is a common turnaround point. You'll soon pass a sign that says Gem Lakes...keep going along this path. After about a mile or so (perhaps longer, hard to judge) you'll see a makeshift large post (discarded tree branch?) on the right of the trail - this post actually has the word "gem" etched in it and directs you to your right, down a small fork. Take this fork about another half mile to the main Gem Lake - in our opinion, this was BY FAR the most gorgeous lake we spent time at. Very few people, nearly unreal shades of turquoise and cobalt within the water and with plenty of areas to eat lunch and rest in solitude.
Total distance round trip from the trailhead to Gem Lake was about 6 miles. Chickenfoot round trip seems to be about in the 4-5 mile ballpark. Generally speaking, the trail is fairly flat, but there are some ups and downs - couple that with the fact that the trailhead itself is about 10,000 in elevation, and Gem Lakes is at ~11,200 I believe. So if you're totally out of shape, I would say that this hike may be doable but still a bit hard due to the elevation.
If you're doing the hike in the summer or fall, would highly recommend starting as early as possible and meandering in slowly. The sun at noon was pretty hot and despite sunscreen we both got a little burned. There are fairly clean bathrooms with toilet paper at the trailhead and in the overflow parking lots.
Easily a must-do hike of the Eastern Sierras/Mammoth region, especially if you're into iridescent lakes, towering pine forests, and crazy cliffs of granite and all that good stuff. read more
