Mosquito Flats Walk-in Campground - Search Nearby - Added by The Outbound Collective

The Mosquito Flat to Morgan Lakes is a 10.7 mile hike in the Eastern Sierra Inyo National Forest. The trail features numerous gorgeous lakes and is used for day hikes and overnight backpacking trips.

This trail is best hiked from July through October, due to high levels of snow at elevation in the Sierras. Dogs are allowed in this area. 

Mosquito Flat Campground is at the very end of the road - right past Rock Creek Lake off of Rock Creek Road. The trailhead is called Little Lakes Valley. This is a popular location for day hikes, camping, and overnight trips, so the closest parking lot fills by 9am on weekdays and 8am on weekends. There are more parking places down the road if the closest lot is full. 

On the trail, you will first pass a junction to Mono Pass which leads to Pioneer Basin (an amazing 5 day backpacking trip). You then pass Mack and Marsh Lakes. When you are approaching the gorgeous Heart lake, you will go over a small bridge. People fish here. Next is Box Lake, then Long Lake. After Long Lake there is a sign for Chickenfoot Lake. After Long Lake the elevation increases as you head toward Gem Lakes. Then you come upon a sign that directs you to take a left to go to Morgan Pass. 

The mosquitos are very active in this area so bring extra repellent and keep your tent doors zipped shut if you are spending the night.
