Drela Dzong or Drela Samten Choekhor is located at 3600m and is commonly called Bjelela Dzong. It is believed that the Zhabdrung Ngawang Namgyal met Pal Yeshey Goenpo in person at this place. It can be reached after a short descent through rhododendron and oak forest to a ridge up and down to Drela Dzong and back to Shaba.
