Know Before You Go
You can get directions from the villagers in Lapinha da Serra, but the route is pretty straightforward. Once you get to the starting point in the village, you just need to follow the paths and trails most visible on the ground. You will have to cross through several private properties, which is fine. This is not trespassing (since these are private natural reserve patrimony), as long as you stay on the path. On the way you will find and cross unlocked gates. These are the limits on each of the properties. Count seven of these gates and keep going. Follow the path and the sound of water falling, and after a couple of hills, you will reach Cachoeira do Lajeado. Bring some food and lots of water.
