Yes. Many of our excursions focus on nature and adventure and most of them include a hike. Some hikes will be longer and more intense then the other ones, depending on the excursion. The general rule for excursion that include hiking is that you need to bring: proper hiking shoes, water, sunscreen, mosquito repellent and a rain coat. In case the hike takes places in a rain forest or cloud forest we highly recommend to wear long trousers and long sleeve. For our rafting tours we recommend, besides the already mentioned items, to bring swim gear and shoes or sandals that can get wet.
