There is a sealed road all the way to the monastery but it is also a pleasant hike from Boudha. People from many different Nepali ethnic groups also join the monastery as young boys to become monks.

Kids can join at a tender age and are mostly from families who traditionally send one child to become a monk or a nun. (https://steemitimages.
