In reply to Alan Stark:
The latest update is that the UAE border post is definitely closed, and there is no direct access from Ras Al Khaimah to the Upper reaches of Wad Bih.
However
Providing that winter storms have not blocked Wadi Khab Shamsi, all of the crags in Upper Wadi Bih are still accessible from Dibba, via Wadi Khab Shamsi and over the pass. (4wd is probably required if the track has not recently been graded).
The restrictions in the north have prompted renewed activity elsewhere.
A number of new sports routes have been developed in the Wonderwall area, near Al Ain, in the south of the region, with 1&2 pitch routes being bolted and climbed. (up to Fr 6b so far, with loads of scope for more routes)
