Soaring, curved walls of windows give this modern, three-bedroom villa the feel of an observatory. And there's plenty to look at: the property, set on ten private acres on Kauai's North Shore, overlooks the golden sand and rolling waves of Pila'a Beach below. The interiors here make use of gorgeous native hardwoods and stone, and include a chef's kitchen, a home theater, and a master suite with a freestanding stone tub. A screened, cane-roofed dining gazebo invites semi-alfresco meals; gas-powered tiki torches light a path that leads to a private beach. From $1,700/night.
