I visited another State Park that composes this WHS: Intervales. Atlantic Forest South-East is the only WHS in the State of São Paulo and some pristine areas of the State are within it. My favorites are Cardoso Island (a remote area where cars and new inhabitants are prohibited) and PETAR (full of caves, waterfalls and crystal-clear rivers). Intervales was a private area until 1995, when it became a State Park. The buildings formerly used for private purposes now belong to the State of São Paulo and are used as lodges. Interestingly, they are inside the park so that you can start your trekkings right after leaving front door. Intervales also has caves, waterfalls, cloud subtropical forest and rivers, none of those are as remarkable as the mentioned beforehand. But it is a delight for two or three days and I fully enjoyed being surrounded by nature for a long weekend.
