many of the hikes can be quite physically demanding, so it is important that participants are in appropriate physical condition for the trip, whilst also researching the trail to know what they are undertaking.  

participants should also be sure to have the correct safety equipment and supplies for the hike, including first-aid and safety kits.

a good pair of hiking boots are advised, as well as sufficient water, usually about one or two liters, and some snacks, as it can be dangerous to run out of energy during a hike.

due to rio's tropical climate it is also a good idea to take some insect repellant, and some sunscreen, even a sun-protecting hat, depending on the hike.
