Are you doing the High Sierra Camps loop? 'Cause that’s available only on a lottery system. Other than that, most of the backpacking “camps” outside of Yosemite Valley are FCFS, and with a wilderness permit (for a large group you’ll want to reserve in advance, but they save a percentage of permits for “day of” issuance) you can camp anywhere that is (going from memory) 4 miles in from a trailhead and 200 meters off-trail and away from a water source.
I tend to prefer North Yosemite because of the variety, but I also go early in the season. By August, the main trails neary the Valley will be thick with tourists, and forget going up Half-Dome without a couple hours wait. Honestly, around that time of the season I’d personally hit one of the other National Park/Forest areas like Inyo or the Trinity Alps, which are less celebrated and somewhat less accessible, but equal if not superior in beauty.
And, not to discourage you–there’s some great natural beauty at Yosemite–but I find the adoration of it to be somewhat overstated. It just doesn’t compare to the Grand Tetons or Denali National Park, or even other parts of the Sierras (like the aforementioned Trinity Alps). Part of that is no doubt my desire to avoid crowds, but I’m still just a little underwhelmed. It’s still a great trip, but not my favorite. If there’s one thing you definitely should see, I’d say it’s the Grand Canyon of the Tuolumne, which doesn’t quite live up to its namesake but is beautiful nonetheless, especially the Meadows area.
Not being certain how much backpacking experience you’ve had I’ll offer up a few tips:[ul]
[li]Bear cannisters/vaults are required outside of Loop campsites (which provide fixed safes). You can rent them at a ranger station for a modest fee, or bring your own. I like the clear Garcia-types, but they have the black ones where the lid folds inward, limiiting capacity. They warn you to keep all “foodstuff” including lotions, toothpaste, et cetera in your cannister at all times except when preparing and eating. [/li][li]Whenever I go the rangers are always warning about “bear activity”, but a quick check of stats shows no fatalities from black bears in the latter half of the century, and while I’ve seen plenty of bearsign, I’ve never seen an actual bear in Yosemite. If you follow food procedures above and travel in a group you’re probably never even going to see a bear. If you do, stay together, stand upright, and make noise/throw stones. With spare exceptions, black bears are not aggressive or predatory.[/li][li]Be prepared for sudden storms at any time; the High Sierras are notorious for bad weather even in mid-summer. August is a little early for snow or flash but it’s not unheard of. Take rain gear, et cetera.[/li][li]Don’t be like those yahoos who are ten miles in and ask me where they’re at/if they can see my map/do I know what is on this trail. Get a map and compass, and know how to use it. [/li][li]Water shouldn’t be an issue at any time of the year except at the highest altitudes, but you will need to purify before drinking. A good filter and a couple of 1l Nalgene bottles will serve your needs.[/li][li]No open fires outside of campsites. While the park is wet, it’s also pine country, and fire travels quickly, threatening both wildlife and people. Use a stove.[/ul]Good luck, and have fun.[/li]
