Sheets, quilts, pillows may seem strange bedfellows for the open air, but these are cozy sleeping platforms that referee civilization and nature. Here are nine of the most spectacular hotel suites in the world.Amangiri Resort
Lake Powell, Canyon Point, Utah
A full moon showcases the mesas against the sky. At night the occasional coyote yips, and at dawn bighorn sheep may troop by. Welcome to Amangiri, the extravagant 600-acre resort near the Navajo Nation in Utah as it cuts in near Page, Arizona. This is one of the best places in the United States for star-gazing: The air is clear and dry, and there's very little ambient light. If you'd like less exposure but a more focused relationship with the starry pitch above, six Amangiri suites have "Sky Terraces" – three protecting walls with the open sky above and a pool below you. With summer nights in the 60s and January nights in the mid-30s or lower, there's appropriate bedding – from silk and wool throws to plumped down quilts. Cocoa with a shot of brandy? Coffee at 5:30 a.m.? This is Amangiri (435-675-3999; suites, $1,500–$3,500).
