If you are the adventurous type who enjoys all that nature has to offer Cachoeira do Horto is the place for you! Located within the immense National Park, Floresta de Tijuca, that the city of Rio de Janeiro encircles, is the gorgeous series of three waterfalls. These waterfalls are in the suburb, Jardim Botanico and are but a simple bus trip, or car trip and even walk if you're up for it, away. Although I must warn the small trek to reach these waterfalls is a moderate challenge and not for those who have weak knees, as there is scaling of rocks, and hefty inclines. The trek as I said is short and can be all done barefoot or even in your Havaianas, that is if you are courageous enough. The best time to visit these waterfalls is anytime in the day before 16:30, the icy chills from the fresh water are a perfect substitute for those trying to escape the chaos of the beach or just trying to escape the crazy summer heat.
An added bonus to the short trek to the waterfalls is the tropical wildlife that surrounds you, on my trip there I was greeted by some monkeys. Although I am fairly certain they only came out because of the food that one of the groups in front of us removed from their bags.
If you are up for the trip here is the address to the waterfalls:
Estrada Dona Castorina, 22 - Jardim Botanico, Rio - Rio de Janeiro, 22460-320, Brazil
P.S. It's FREE, best way to spend a day when you're on a tight budget!
