If you follow the river up from Haus Rock, pull off or park on the next pulloff to the right walk up river to find the crossing. Then walk back down the river trail and look for a trail going up the hill.
So, the rope crossing is no longer available to access this crag...at least from the hiking up and downstream my homies and I have done. There is a bridge, but it is on private property. So do that at your own risk if you want to, but after fording the river, follow the trail west to a cairn on the south side of the trail. That will basically be the beginning of the approach. Great area with a lot of solid routes. Lots of sport and a few trad lines. Good times if you would like to avoid Haus Rock and its popularity on the weekends. Best book on the area that I have seen thus far is the Summit Climbing Guide by Rick & Laura Karden.
