The Rio Vermelho in Santa Catarina, Brazil, flows through the protected Rio Vermelho State Park, a significant area for paddling and outdoor recreation. The park is located on Santa Catarina Island near Florianopolis. Public access to the park and its trails is free, with entry available 24 hours a day via an unpaved road that passes through a restinga ecosystem. The primary paddling activity is a guided tour offered by the operator Adrenailha, which provides kayaks, canoes, or stand-up paddleboards along with personal flotation devices and oars. These tours include transportation to and from the Rio Vermelho State Park, training in canoeing techniques, and information about the region. The tours navigate a route that includes lagoons and the Red River itself, utilizing semi-oceanic kayaks equipped with rudders. While the river itself is the central feature, the park also contains the Cachoeira do Rio Vermelho waterfall. The hike to reach this waterfall is considered intermediate, involving a long uphill section and a final, very steep descent, indicating rugged terrain within the park. The area offers a blend of aquatic and forested environments characteristic of the island's coastal region.
