hey vdub.. grew up there til he age of 17, had a well good time. if your in hwest then its a pretty good base for north and south pembs. in my opinion the north is more for hill walking and biking (thats where the howies lot go) and the south has more of the touristy towns etc.
as for stuff to do:
tenby is nice town to spend the day, nice beach to sunbath and swim, good places to eat, fishing trips etc.
bit further up the coast in newgale. really good surfing beach, board hire etc.
somewhere a bit lower key but along the same lines as tenby is st davids, cafe’s, cathedral, theres a beach called whitesands on its door step too which hire out surf boards and the beach itself is lovely.
little bit further around the coast is a place called ‘blue lagoon’ it’ll be called abereiddy on the map. basically it was an old slate mine and they blew it up which left a 100ft+ deep lagoon and you can jump off 40ft+ cliff jumps into the lagoon from the slate stacks on the opposite side. WELL GOOD FUN.
pretty much the next beach up the coast is porthgain which has an awesome pub called the sloop. does brilliant food, worth going to after the blue lagoon.
er.. can’t think of anything else.. but yeah, outdoors stuff head to the preseli’s. give me an email on mafu26 at hotmail dot com if you want any more info
enjoy!
