Get yourslf onto the m4 and take the junction for Llanelli I think it's 48 but I'm not sure anyway it's the last one-if you run out of motorway you've gone too far. For Cefn Sidan head into Llanelli and through it following the signs for Pembrey country park as you turn off the main road in Pembrey you follow the road round and over the railway bridge. There is a long straight road which has a couple of WW2 pillboxes on it. If you continue along this you will come to the entrance to the country park which is a nice place to visit and does have beach access although it's quite a walk , can be unfishable due to the number of visitors in Summer and costs a fiver to enter. A better option is that as the main entrance road bends right there is a turning left turn here; there is a car park here and a soccer field. Go straight ahead and you'll see a single track road ahead of you with high steel railings on your right and bushes on your left. Follow this road-it's not the smoothest but quite passable. Take care as it's only single track and it is not always possible to see vehicles coming the other way. Where the railings turn right the road follows them around keep going. Where the road forks take the left one-you'll soon find out if you've gone wrong because the right fork is a dead end.There is a water treatment plant on your right go past this. Keep on the road and you'll come to a place where there is a cross roads go straight on (incidentaly if you turn right and park you can step over the barrier and get into the country park foc) A little way further on the track broadens out into a car park that's it. It's free and there are no barriers so it's open 24/7. There is a track over the dunes which leads you onto the beach, it looks passable but if you're not in a 4x4 do not be tempted-YOU WILL GET STUCK- If you are in a 4x4 you can access the beach this way, but again a note of caution it is also single track and the final dune before the beach itself is quite steep and the going is not good-this is not such a problem going on to the beach but some 4x4s that are not as capable as, say a Landrover need a run up to get off the beach and it is a good idea to stop and check before making the climb, once on the beach be aware that there are some rather nasty little humps before you reach hard sand. If anyone does plan on using their vehicle on the beach could you please read my post on beach etiquette ( non-fishing chat) BEFORE doing so-this is important because it is only by adhering to a code of practice that this privilege might remain and not be revoked by the powers that be.Hope this is clear but don't hesitate to ask if it's not.
