As you probably know, both areas have much better trad options than sport, but still...
As mentioned above, Snake Dike is a fantastic day out in Yosemite as long as you're comfortable with easy runouts (maybe take just a few nuts and cams in the 0.3-1 inch range as well, the supertopo guide probably lists exactly which ones you need and where).
There's also some bolted routes at Knob Hill (Just for Starters and some newer routes on the wall/slabs under it... not sure if they're in the guides), at Pat and Jack Pinnacle (Boneheads, Makayla's Climb and Knuckleheads, though the last one is a bit more hairy) and a few routes at Schultz's Ridge.
You could also head up into Tuolumne meadows if the cold weather isn't hitting yet - lots of bolted stuff scattered about up there (Shagadelic, Witch of the West, the routes on the Bunny Slopes...). It's a pretty beautiful part of the world.
In J. Tree there are plenty of easy-ish sports slabs in the Echo Rock area that will fill in a day fairly nicely. Walk on the Wild Side (a multipitch 5.7 on saddle rock) may also be worth a shot.
Have yourself a blast... |
