I was walking on the preselis today…ain't going to be ANY cycling on those hills this summer…standing water in the usual dry bits and the bogs have tripled in size. Fingers crossed for a cold winter so it'll freeze!
Other wise you haven't got many choices…round where I work in Stackpole (south of Pembroke) there are 2 woods owned by the NT which have permissive trails for bikes in them, we take kids cycling there and it's good for intro sessions, unfortunately most of the trails are deep in mud at the mo, and we have some REALLY thoughtless horse riders round here.
ALso you can have a little play on the bridleways and lanes round Strumble Head…go down to the lighthouse for some whale watching. Park in Mathry so you can finish with a pint. 🙂
Mal-ec and hitman, fancy meeting up for a ride in one of the shit parts of our lovely county?
