Hi steve.....seem to be letting everybody down at the mo!
Only just got your message, and had one from John Climber about beach riding on the 8th as well!
Pretty battered with work currentlty, which is seasonal based and xmas is our busiest time of year.
As i posted to John, i'm b*****ked until the New Year, soz.
Have you looked at at parking at Pen-lon 432643 grid ref, the warren beach area looks very "fatable" from previous walks in the area i have done.
Also Angelsey now has a COMPLETE coast path, possible if you like portage?
