Buried deep in the middle of the Balinese jungle and surrounded on two sides by flowing river banks, Como Shambhala Estate offers visitors a chance to experience the musts of a healthy getaway — deep-sea mud baths, incredible massages, yoga sessions and intense hiking — mixed in with the unforgettable and unexpected, like an Ayurvedic healing session with a local shaman or a bike ride through miles of rice paddies. And while the estate is billed as a health spa, with its individual villas perched above the jungle and an infinity pool that seems to spill into the mountains, this tropical paradise exists in a category of its own: part spiritual retreat, part travel adventure and 100 percent what the doctor ordered.
