Ben Nevis is located in Scotland and is the highest mountain in the British Isles, standing at 1,344 meters tall. It attracts around 100,000 climbers a year, with many using the well-constructed pony track from Glen Nevis. The mountain is known for its 700-meter high cliffs on the north face, which harbor rock climbs and ice climbs and are a main location for climbing in the UK. An observatory once stood at the summit from 1883 to 1904.
