Yellowjacket Crags Rock Climbing

Park at the picnic area where Highway 49 and the northern end of Mad River Road intersect. Walk a bit up 49 until you can see an old logging road across the street. Walk up this road until it becomes a trail. You'll see the main stream come in from the right. (The idea is to follow this stream as this stream will eventually lead you directly to the boulders.)

The trail crisscrosses a bunch of cross country ski trails, but keep following the main stream into the woods. After about a third of a mile, you'll end up on the Yellowjacket Ski Trail. Once on this trail, follow it for a couple hundred yards until the stream crosses under the trail at a wooden bridge (this would be the second bridge you've crossed). Once over the bridge, head left into the woods.

Once in the woods, follow a small climber's trail up the stream bed, and look for periodic cairns. As long as you follow the stream, you can't get lost. You will come to some average-looking boulders on the left after about 4/10ths of a mile. Keep heading up the stream bed for another few minutes and you'll see the Yellowjacket Boulder. Continue following the trail up hill above the YJ boulder. There will be a trail split a few minutes up from there, take the right fork. Walk another 5 minutes (past some large boulders right on the trail) when the trail levels out look for an open area. If you are headed to Cavern Cliff Area take a climbers trail to the left. To get to the slab lands continue up the trail you are on until you see the cliffs on your left.
