Climb up relatively easy holds to a tufa. Getting past it seems to have a height-dependent move. Easier climbing leads to a second small tufa up top. Get onto the ledge above the tufa and head up to find one more bolt and the anchors all the way at the top.
Refer to the pictures posted here and also to the map mentioned on the area page under the "Getting There" section.
