These photos were taken during a camping holiday a few years ago in North Yorkshire. We left the car at Ribblehead Station then took a train to Dent, which is the next station up the line on the Settle and Carlisle Railway. The train takes you over the Ribblehead Viaduct and then through a long tunnel.
The walk back is over the hill that the tunnel goes through. This takes you up a very steep track through a forest before you emerge on the open fells, which is where several of these photos were taken.
Peaceful is the word I would use.
