We spent our second few days at Gwern Y Bwlch in June.  We had a superb pitch and this time even managed TV reception.  It is one of the prettiest locations and although the pitches are all individual and within a relatively small area- you feel you are in a private location and amidst trees and countryside.  We only walked out, but the bus service is good and the location is accessible. The two pitches across the lane and indeed virtually all the pitches make you feel very special- as if you are sharing some ones private garden.  Stock up your van freezer, come here, bring your book and recuperate from the hectic life of work.
