Gangkhar Puensum

Gangkhar Puensum is probably the highest unclimbed mountain in the world, although some people have tried to scale this 3,000-metre peak in Bhutan—an unusual destination worth adding to your bucket list. Like many tall mountains, this one is unmapped—although unlike other mountains, it remains uncharted for spiritual reasons. To locals, some areas in the mountains are the refuge of centuries-old buddhist saints and the mountains themselves homes to gods and goddesses. Although climbers hoping to scale tall peaks like this one could use Google Earth to get an idea of what they’re in for, BBC Future points out many consider that cheating.
