10 Incredible Nighttime Adventures That Take Stargazing to New Heights

If you want to see stars that glow instead of twinkle, head up a seriously high mountain. So clear is the night sky at altitude that most of the world's most advanced telescopes – such as the Very Large Telescope and ALMA – perch on mountains as tall as 16,400 feet in Chile's Atacama Desert. The epic 10-day Atacama Horse Adventure travels from San Pedro de Atacama to Calama via salt flats, petroglyphs, and the mysterious Moon Valley. Prepare for plenty of sleeps under a star-studded sky.
