A well-maintained, easy-to-follow pilgrimage and hiking trail takes around four hours from Nako to a remote monastery at Tashigang hamlet. Guru Padmasambhava is believed to have meditated and taught here and hardcore hikers can continue about two hours to caves and a tiny monastery at Tsomang (or Somang).
After climbing steeply to Nako Pass, the trail is reasonably level albeit undulating, and very high at around 3850m all the way. Around halfway, 10 minutes beyond the stream crossing, a spring provides fresh water. It's possible to sleep and eat at the Tashigang monastery: take a gift for the monks by way of donation (sugar is appreciated). Nako authorities prefer that tourists take a guide, though the path is clear and many people go without one.
