Hi Gecko,if your campsite is Fforest Farm at Hundred House I live less than 1mile from there.
Don't have GPS still navigate by the sun and maps,however could meet you on site to chat about routes etc and also ride to Abercrave.
Riding off road around here is getting difficult due to complaints. The police and countryside wardens are stopping bikers on the hills and greenlanes.
If you want I can pm my phone number
