Carijós Ecological Station, Ecological station in Florianópolis, Brazil.

Carijós Ecological Station is a fully protected coastal marine reserve on Santa Catarina Island in Florianópolis, Santa Catarina, Brazil. It covers 7.5933 square kilometres and is made up of two mangrove areas, Ratones and Saco Grande, within the Atlantic forest biome. The Ratones mangrove is reached via the SC-402 highway toward Jurerê and Daniela beach, the Saco Grande mangrove via the SC-401 highway from the Monte Verde overpass. It is managed by the Chico Mendes Institute for Biodiversity Conservation.

Brazil's government established this protected coastal area in 1987 to safeguard the mangrove ecosystem on Santa Catarina Island. The creation addressed growing concerns about habitat loss in the region.

The station protects the mangroves of Ratones and Saco Grande, two sectors reached from the SC-402 and SC-401 highways respectively. Its name is written Carijós, without any documented link to the Guarani in the sources. Access is reserved for environmental education, so the area is not used for local heritage gatherings.

The station is located roughly 20 kilometers from downtown Florianópolis and accepts visitors only for environmental education activities. Plan to join a guided program or educational visit to experience the protected area properly.

A systematic research project beginning in 2013 first documented diseases and parasites affecting the local bird population. This study provided important insights into the ecosystem's overall health.
