In reply to GLUF:
The Chasms is bird banned now until well after TT week. There are other areas but where to go depends on the climber as much as anything else.
Manx climbing is adventurous stuff, think Gogarth with a false beard and a squint. The chasms is certainly the main area with routes of all grades and sillinesses. After The Chasms then Aldrick is probably the next choice venue for routes but is of quite variable quality. There is a top secret sport crag (details in the UKC logbook) but as it only has half a dozen routes, mostly in the upper 7's/low 8's and has a fairly epic "walk" in it probably lacks mass appeal. Bouldering is available at Peel and at Laxey beach. Other venues are increasingly esoteric but there is quality climbing to be had.
Drop me an email with details of when you're heading over and I can try and meet up with you, or at least provide an introduction to the small hardcore of oddlings that climb round there ere parts...
