A trip to the dinosaur park at Gumfreston near Tenby can be an enjoyable experience if you are able bodied.  If you are not and are confined to a wheelchair, then make sure you have someone very strong to push you along the paths.  Some areas are ideal for wheelchair users with wooden decking, but, there are areas where the decking vanishes and a combination of tree roots, and in one area, a sudden steeply rising path make it impossible for the lone wheelchair traveller.  But for all the difficulties on the way round, the dinosaurs are well created and atmospheric noises give a sense of being in the prehistoric world.
