The reason you come to Twitch Rock is for the beast itself, Twitch (5.12d). There is now a nice little warm up here so this wall can be a one-stop shop. With morning shade, it makes for sending temps late into the summer months.
Approach: Located on the east side of Tunnel 2 on the north side of the road, drive 6.0 miles up the canyon and park at a long, narrow pullout on the north (right) side of the road. After parking, walk towards the tunnel; the approach trail will be on the north side of the road. Take this trail east/downhill for a few hundred feet until taking a short trail uphill to reach the base of the cliff that is slightly hidden by a tree.
