Since Jan 2020, permits are required (despite the crags being on MCSA land) and are purchased from Tranquilitas Camp ground.
Facing down-valley from the campsite office, walk down toward the stream on your left, until you cross a prominent path (which starts near Challet 2). This path crosses the stream through bushy underbrush and then exits to follow the cliff-line (lefthand) and is the common path for access to Hallucinogen and Superbowl.
Hallucinogen has an acces path on either end of the (long) crag.
