When it comes to waterfalls, we are spoilt for choice in the North of England.
One of my favourite falls is Wain Wath Force on the river Swale, Yorkshire. (Right next to the road).
There are waterfalls spread over a longer stretch of river at Aysgarth, and higher, longer drop falls at Mallyan Spout, Goathland. Mallyan Spout is reached by foot via the valley to the rear of the Mallyan Spout Hotel. The waterfall boasts a drop of almost 70 feet.
The waterfall trail at Ingleton passes many waterfalls.
