Approach by abseil - 50m will get you to the niche for lighthouse direct but take care your ropes don't get trapped by the undertow at the base of the crag. Please take care with the rigging, the pegs are very old and should be backed up with extra gear.
Although there are no restrictions due to nesting birds, guillemots do occasionally nest on the breaks below the halfway ledge, close to the first pitches of Pel and North West Passage. If this is the case try to climb to one side of the nests and avoid going directly past it. These few birds that do nest here seem to be very tolerant of climbers as long as we climb past quickly...!
Parking and Approach
From the South Stack Visitor Centre car park head down towards Elin's tower, cross the wall just to the right of the tower and carefully make your way down to a small ledge where most people rack up. There is an alternative abseil 15m up to the right which can be used for accessing routes on the right hand side of Rap (climbers right).
