Don’t undermine the sun, in particular when crossing snow fields or large camps of bright volcanic ash. A proper head cover, sun cream and sun glasses are essential to prevent sun-burns and snow-blindness. Don’t just carry this stuff but use it preventively.

The Greater Patagonian Trail snakes through the [https://en.wikipedia.org/wiki/Andean_Volcanic_Belt#Southern_Volcanic_Zone Southern Volcanic Zone] and passes and crosses numerous volcanos. The trail is therefore plastered with signs of volcanic activities. Hot springs and beautiful mountain lakes that were dammed up by lava flows are the "sunny side" of these volcanic activities; widespread devastating destruction is the other. Several major eruptions occured in the vicinity of the trail in recent years and parts of the trail were temporarily closed due to increased volcanic activities.
