The Rio Vermelho in Santa Catarina, Brazil, flows through the Rio Vermelho State Park, a protected area on Santa Catarina Island near Florianopolis. Paddling here is primarily facilitated by guided tours, such as those offered by Adrenailha, which provide kayaks, canoes, or stand-up paddleboards along with vests, oars, and transportation to and from the park. These tours typically include training in canoeing techniques and information about the region, and they navigate a semi-oceanic environment that includes lagoons and the river itself. Public visitation to the park is free on its trails, which are accessed via an unpaved road through a restinga ecosystem, though specific public water access points for independent paddlers are not detailed. The park features a notable waterfall, the Cachoeira do Rio Vermelho, located near Santo Amaro da Imperatriz. The hike to reach this waterfall is described as intermediate level, involving a long uphill stretch with some steep sections followed by a shorter but very steep descent. The overall character of the paddling experience is centered on adventure tourism within a coastal state park setting, combining aquatic trails with natural exploration. The park is open 24 hours, and while water temperature patterns, exact size, water quality, and specific wildlife are not detailed, the environment includes restinga and semi-oceanic waters indicative of the region's diverse coastal ecology.
