Are national parks and reserves safe?
For the most part, Guatemala’s national parks and reserves are safe. Larger animals like jaguars keep clear of people. Snakes and spiders can be dangerous and present, but if you're smart about where you walk you should be fine. Stay on trails and be careful around piles of leaves or rocks.
Mosquitos can be pesky in the jungle and also transmit disease. For this reason, when you visit a national park or reserve it's important to wear insect repellent and long sleeves/pants if possible.
