Pembroke - Pembroke is a huge area of limestone and volcanic sea cliffs in South Wales. It's miles from anywhere, there's little to do if it rains, some of the climbing has seasonal nesting restrictions and some can only be accessed at weekends when the army allow people on to their firing ranges. Despite all this the area has much in it's favour:
a) The climate is pretty good (for Britain!)
b) Even during restricted periods there will hundreds of brilliant routes to keep you going - the guidebook has over 800 pages.
c) It's probably the most friendly and conducive sea cliff area with good protection, solid rock and positive holds.
The best base is around Bosherston (near Milford Haven) where there is a very basic campsite and an excellent pub and cafe, but little else! More luxurious camping facilities are available at St Petrox, a short distance away. Although highly regarded, this area is very rarely crowded apart from during the English Bank holidays. The first weekend in May is particularly popular when there is a great community atmosphere around the crags, campsite and pub.
There are too many quality routes to pick out individual ones but St. Govan's Head is ideal for first-timers and Huntsman's Leap is well worth a look. It's a tidal gorge which is narrow enough at it's seaward end to be jumped by lunatics - ropes advised, horses not recommended!
To the north the slabs of Carreg-Y-Barcud near St Davids offer a pleasant contrast to the strenuous South Pembroke walls.
