When driving up the Rock Creek Road from Tom's Place one begins to get a direct taste of the grandeur of this marvelous area of the Eastern Sierra. First, the massive Mount Morgan South at 13,748' looms ahead. A few miles further along there is Bear Creek Spire, Mount Dade and Mount Abbot, all high thirteeners that come into view beyond Rock Creek Lake. A couple more miles bring you to the Mosquito Flat trailhead parking. A short hike of less than a mile and you're in the heart of Little Lakes Valley surrounded by some of the most beautiful scenery the high Sierra has to offer. With a starting elevation of 10,230' at the parking area, and an excellent trail system, one has easy access to a great cirque of peaks and two major passes into the backcountry that can all be done in a day.
The valley is packed with sparkling trailside lakes and streams with lofty granite giants on all sides.
This is truly a mountain lovers paradise for hiking, fly fishing, camping and climbing. With all this being the case the area is a very popular destination in the summer. Everything from short 1-2 hour strolls up to Marsh or Heart Lake to extensive climbing/backpacking adventures along the crest or over the passes await.

Rock Climbing Stepping up the technical level, on the west side of the canyon you will find Iris Slab, an 80’ low angle, east-facing rock and a great place for easy trad routes and top-roping. Winter Activities During winter, the U.S. Forest Service’s East Fork Sno-Park area, located about 6 miles up Rock Creek Road from Tom’s Place, can be enjoyed. There is a $5 per day fee to use this area. In this area, you can find yourself a nice spot for a camp and conduct winter activities from your camp, be it snowshoeing, skiing or climbing. If cross-country skiing on groomed trails entices you, several mainly flat terrain routes start at the Sno-Park. One of the routes is to Mosquito Flats trailhead and then on towards Bear Creek Spire. At dinner time, snowshoe or ski up Rock Creek Road to the Rock Creek Lodge where you can enjoy some hearty fare at the lodge’s eating facility.
Although there are other places in the Rock Creek Canyon area worthy of visit (for example, the Hilton Lakes area and Tamarack Trailhead located at Rock Creek Lake), the focus here is on Little Lakes Basin and its environs. Hiking Little Lakes Valley is a basin where numerous high-elevation lakes are linked by excellent hiking trails and ringed by 13,000 foot peaks. It is alpine beauty personified. FURTHERMORE, IT IS ALMOST A SIN WHAT BEAUTY IS ACCESSIBLE WITH VERY MINIMAL EFFORT ALONG LITTLE LAKES VALLEY TRAIL. There is no better place for introductory hiking than the Little Lakes Valley Trail. Within 30 minutes of easy hiking, and with minimal elevation gain (remember you start from 10,300’) you can reach the first of several alpine lakes of stunning beauty; among others, Mack, Marsh, Heart, Hidden Lakes and Long Lake. Because most of these lakes provide excellent campsite areas, they are ideal for beginning backpackers and for family backpack outings with small children.
Cross-Country Runners One strenuous activity you might not normally associate with Little Lakes Valley is cross-country training. But during August, the Mosquito Flats Trailhead becomes a popular spot for high school cross-country coaches to unleash their charges on the mountain to do their summer training. Fishing Fishing is a popular activity along the string of lakes in this basin with small brook trout being the most prevalent catch. There are also 3-5 pound browns to be caught and some lakes have wild rainbow trout as well.
Horse/Mule pack outings
If you don’t want to carry a pack, the Rock Creek Pack Station can set you up with a pack outing so can travel in the saddle and let mules do the heavy work.

Continue on the Mono Pass Trail as it climbs up to the right then turns right and climbs up to the pass at 3 miles (12,040'). This leads down into Pioneer Basin. Morgan Pass Trail: Take the main trail .5 miles to the junction with the Mono Pass Trail (10,440') and stay to the left continuing up the valley 3.5 miles to Morgan Pass at (11,080').

A highly recommended day hike from the Mosquito Flats Trailhead is to Ruby Lake. Along the Little Lakes Valley Trail, the turn-off for Ruby Lake is about ½ mile from the trailhead. On the ascent, you will get incredible views of Little Lakes Valley below. Just below the lake, you encounter marvelous cascades from the drainage above. Ruby Lake is an eye-catching, relatively secluded alpine lake at 11,140’elevation and a great spot for lunch.
From here, one option would be to continue up the trail towards Mono Pass (elev. 12,045’). The Mono Pass Trail continues west over the Sierra Crest and drops into the Mono Creek Recesses and Pioneer Basin (the latter a popular pack station trip destination). A more adventurous alternative is to head SW cross-country up the terrain above Ruby Lake toward the snowfields below Mt. Abbot. In your line of sight, adjoining Mt. Abbot, will be the beautiful pinnacle known as Petit Grifon (it features a 5.7 alpine route to its tiny summit). You will be scrambling up the drainage alongside the snow melt coming down under the rocks, alternating with level areas where small lakes have formed. It will feel like real adventure in a pristine alpine setting.
If you want to find excellent outlying campsites, pack all the way along Little Lakes Valley Trail to Gem Lakes and you will have an abundance of possible campsites amongst the lakes there. Gem Lakes is only some 4-5 miles from the trailhead with only 700’ of gain. As you hike, be on the look out for a spot where the trees frame a gap with Bear Creek Spire at dead center. It’s a photo op not to be missed. From your campsite at Gem Lakes, you can plan day hikes of Bear Creek Spire, Mt. Dade or Pyramid Peak, to name just a few. In the winter, you can reach Treasure Lakes with a little cross-country jaunt off the Little Lakes Valley Trail and use the area as a base camp to do a classic snow climb like Mt. Dade’s Hourglass Couloir.
If you wish, you can continue past the Gem Lakes turn-off and continue up toward Morgan Pass (11,155’). Over this pass, you will drop SE along Morgan Creek to Upper Morgan Lake and Lower Morgan Lake.
