Hikers need to be well-prepared in Chile – trails can be challenging, with few other hikers if you get into any problems. Take all usual precautions in terms of water, sun protection, good maps and compass. Also carry extra layers of warm clothing, as temperatures can drop suddenly, particularly after sundown.
Chile is a very safe country, but take usual precautions against theft in cities.
Chile sits on major earthquake faults, and has suffered some devastating quakes – its devastating 1960 quake was the largest ever recorded, notching 9.5 on the Richter scale. You can't protect yourself against earthquakes – but the odds of one affecting your holiday are vanishingly small.
