From Silver LakeA number of hikes starts from Silver Lake and touch Agnew Lake, Gem Lake, Waugh Lake, the Thousand Island Lake and Garnett Lake.
Directions from the Bay Area: drive across Yosemite on 120 to Mono Lake
and turn south (right) on highway 395 to the June Lake loop.
Drive on the June Lake loop to the Silver Lake resort. The parking lot for
the Rush Creek trailhead (2,300m) is on the right hand-side.
From Agnew MeadowIf you keep driving south on highway 395 and turn right onto 203 through Mammoth Lakes and then turn right on Minaret Summit Road and continue past Minaret Summit, you reach the right turn to the Agnew Meadow trailhead (a short dirt road). If you use Agnew Meadow as your entrance to the area (beware that cars are not allowed most of the day), there are three possible trails: the high trail, which is the Pacific Crest Trail (PCT) that takes you straight north to Thousand Island Lake; the river trail that takes you straight north to Thousand Island Lake but stays lower and is therefore shorter; and the Shadow Creek trail that takes you to Shadow Lake, where you pick up the John Muir Trail (JMT) to go north to Garnett Lake and then Thousand Island Lake. The turnout to go south to Minaret Falls is off this third trail (first you have to head north, then you'll find the turnout to go south). The second and third trail are the same trail at the beginning, then they split just before Shadow Lake. Beware that this trail, the "river trail", goes downhill for a long time, which means that on the way back it will be painfully uphill when you are coming back tired.
The shortest route to both Garnett Lake and Thousand Island Lake is the river trail (to actually reach Garnett Lake you'll have to take a very steep detour
but there is a trail that connects the north shore of Garnett and the south shore of Thousand Island).
For example: Agnew Meadow (2530m) north to Thousand Island Lake (3000m, 11 kms) on the river trail, then south to Garnett Lake (3 kms) and back to Agnew Meadow via the river trail (9 kms). Any loop done from here tends to be easier because it starts at higher elevation. But don't underestimate the bureaucracy: you cannot drive your own vehicle to Agnew Meadow during the day. Bureaucrats specialize in ruining a hiker's experience and in making simple things really complicated. See the Mt Ritter page for the Mt Ritter and Banner Peak routes that also start from Agnew Meadow.
Note: the Garnett Lake trail is recommended only to masochists with a good sense of humor.

Mt Ritter and Banner Peak
A nice trail connects Yosemite High Country and the Ansel Adams Wilderness. In Yosemite take the Mono Pass trailhead east of Tuolumne Meadows (west of Tioga Pass) and turn right onto the Parker Pass trail and then cross country to Kuna Peak (third highest in Yosemite), down to to Koip Pass and to Thousand Island Lake in the Ansel Adams Wilderness (from which you can also attempt Banner Peak). Then you can descend to any of the trailheads in the Mammoth area, or return to Yosemite via Donahue Pass and the John Muir trail.
