A heavy red door opens onto this secret garden retreat miles from the modern world. Ease into the 40-foot greenstone pool, indulge in a massage in one of the tucked away balés, and cue up Netflix in an open-air pavilion. Alfresco rain showers and rattan sofas are a nod to historic Bali, and you'll find another kind of outdoor magic on the dark, volcanic sands of Echo Beach 5 miles down the road.
