Cachoeira da Macumba — also known as Cachoeira dos Treze or Poço 13, the latter nickname reflecting its location 13 kilometers from the center of Itaipava — sits along the BR-495, the road connecting Itaipava to Teresópolis in the Petrópolis region of Rio de Janeiro state, roughly 70 kilometers from the city of Rio de Janeiro.

The waterfall is reached via an easy trailhead at the roadside, where visitors park and follow a short path. Staying straight at an early fork leads to a first swimming hole in about 10 minutes, with the main waterfall just 5 minutes beyond.

The water is clear, the trail is beginner-friendly, and the surrounding scenery is lush — making it a popular day-trip destination for those seeking a natural escape from the capital.
