Namobuddha, Thrangu Tashi monastery and Panauti on the south east fo the rim. Namobudha is small shrine that belies its improtantce to Buddhists, the nearby (10 minutes walk) monastery is very impressive with great views and has an associated guesthouse nd Panauti has small historic centre with temples at the conflunce of rivers; the less enlightened can see tow rivers, the more enlightened, three). There are good hikes around too, to villages that get few visitors.
Pharping for monasteries and Padmasambhave/Guru Rinpoche (delete as appropriate) caves, the nearby Dollu monastery and a hike up Champadevi, a popular view point that can be reached from Pharping. The cable car up to the top of Charandagiri is off the beaten path for tourists but popular with locals.
