Rising toward the fading stars high atop the Andes, El Tatio Geysers erupt from more than 80 vents into wraith-like plumes, which dance in the first crisp golden rays of dawn. It's not quite the largest geyser field in the world (it's the third), or the highest (it's close), but combined with those snowcapped volcanoes that encircle its steaming expanse, it is perhaps the most magnificent.
In addition to the searing-hot fumeroles and geysers, the field has a few more inviting geological features. A large 35°C (95°F) hot spring lets you soak away the Andes' stubborn chill, while bubbling mud pots offer the perfect masque for cleansing away weeks of grime from the road. Relax.
