Concierge.com's insider take:

The hype is true: This place really is spectacular. It sits on a narrow ridgeline 1,200 feet above the crashing surf, and its architecture brings out the best in the setting. The buildings are all made from organic materials such as slate, glass, wood, and rusting metal to blend with the landscape; rooflines are stepped to mirror the distant mountains. Of the 30 rooms available, the best are the five Ocean Houses, whose roofs are covered in wildflowers and whose walls of glass overlook the sea. The seven Tree House rooms, built on stilts in the canopy of hundred-year-old gnarled oaks, are also excellent choices. The Post Ranch is a place to escape in privacy; no one under 18 is allowed, and there are no clocks or TVs in the rooms— although there are wood-burning fireplaces, massage tables, walking sticks, bird books, binoculars, and complimentary minibars. Bathtubs lined with unfinished gray marble and beds with denim bedspreads reinforce the luxe-rustic vibe. The three pools (including a cliff-top infinity pool) are open round the clock, so you can follow up your morning yoga, afternoon guided walk, or evening spa service with a soak.
