Another stunning piece of scenery in the park, the Ogwen Valley is cut in half by its eponymous river, giving the whole thing a dramatic aesthetic that could be right out of modern day fantasy. The gorgeousness of it all makes it a magnet for ambitious walkers and climbers alike, men and women eager to conquer the valley and take in all it has to offer. The small town of Bethesa lies on its borders, a place of less than 5,000 people that is mostly known for its slate history.
