What should I wear or bring to a national park in Guatemala?
The trails in Guatemala are not be in poor condition, so it's important to bring a good pair of hiking shoes. Long pants and a long-sleeved shirt will protect you from UV rays and mosquitos, and a hat will keep the sun out of your eyes. It's also a good idea to have a rain jacket on hand, as unexpected showers can occur, especially in the Amazon. Moisture-wicking clothing will allow you to sweat but not get soaked.
Bring a small daypack to carry other items, including a camera, sunscreen, insect repellent, guide books/map, snacks, and a water bottle. Remember to bring water, as there usually aren't water fountains in Peruvian parks and it's important to stay hydrated while hiking.
