The Valley of the Moon (Valle de la Luna) in San Pedro de Atacama, Chile, is a stunning desert landscape renowned for its lunar-like formations, sand dunes, and salt caves, offering breathtaking sunset views. It's generally accessible via organized tours departing from San Pedro de Atacama, which are highly recommended for ease of transport and informative guides; however, independent visits by rental car or bicycle are also possible for those preferring solo exploration, though some areas might be challenging on a bike. The site is open year-round, with the best viewing times being late afternoon to witness the iconic sunset, though extreme temperatures (hot days, cold nights) should be considered depending on the season. Entrance fees are typically around 3,000-5,000 CLP per person (separate from tour costs), and a typical visit duration is 2-3 hours, often as part of a half-day tour. Visitors should bring plenty of water, sun protection (hat, sunscreen), and layers of clothing for temperature changes.
