Every time I go on holiday to Folkestone I ride the RH&DR light railway from the beginning of the line at Hythe to the end of the line Dungeness and back again via a model train museum at New Romney. It's such a wonderful experience because the trains are very small versions of old fashioned steam and diesel trains such as the train featured in Rail. There are also lots of excitable children (which is always lovely to see) and the end destination, Dungeness is like another planet!
Dungeness is basically one gigantic shingle beach where next to nothing can grow. Due to this the power station was built however they needed places to house the workers so little wooden shacks were built. Despite being right next to a power station these shacks are powered by gas canisters as the area is so isolated. Some of the shacks now have been sold off and are galleries.
I like visiting Dungeness as it is so beautiful but also so creepy. You can stand next to the power station looking at the vast expanse of nothing and hear this strange, disembodied, echoing voice floating from the speaker system of the mysterious power station.
If you would also like to visit Dungeness I definitely recommend going via the RH&DR (Romney, Hythe and Dymchurch Railway). It's always a fun ride and some days are eve themed rides such as at Christmas, Halloween and the local festival Day of Syn.
Once at Dungeness you can either eat a picnic on the beach, have a cream tea at the railway café or try some regional food at Dungeness' only pub, The Britannia Inn. There are also cafes / restaurants at Hythe and New Romney.
