Brecon Beacons (west)
Grid ref
10 fig off my garmin)map grid SN, eastings-91713 /northings-08451, my gps' are jam packed with bivi/ wild camp locations throughout the uk- it's like a crime file of everywhere i've slepted out.
In the waterfall country of the beacons, by the old gunpowder works and royal engineers pioneers bridge - spent many a day and night here, built shelters, fires even had some eels out of the river with friends and on my own, no bother - no hassle - open use.
Tip - don't leave your motor in the dinas rock car park.
Good walking country through these woods - the famous Sgwd y elra waterfall that you can walk behind.
Enjoy :-D
