Snowdonia National Park. You can walk (find the trail) or take the Snowdon Mountain railroad to the summit (1,085 meters or 3,560 feet), which is often in mist and clouds!  Sheep farms dot the slopes. Already by 1897, 12,000 visitors climbed the summit; by 1985, 75,500; and by 1996, 156,900.  Click on a picture to see a larger view.
