Subtropical island life with Arvoredo reef dives, Campeche snorkeling, and Atlantic Forest trails
Updated Jan 23, 2026 • 20 sources
Overview
Florianopolis sits on Santa Catarina Island, where Atlantic Forest cliffs, dunes, and fishing villages meet the South Atlantic. For underwater travelers, the headline is boat diving near the Arvoredo archipelago. It is a fully protected biological reserve, and recreational diving is restricted to the southern tip of Ilha do Arvoredo outside the reserve boundary, with no landings except emergencies. Expect rocky reefs, boulder fields, and frequent turtle sightings, plus local island dives like Ilha do Xavier for training and easy wildlife encounters. Topside, you can beach-hop between surf breaks and calm bays, paddle Lagoa da Conceicao at sunset, hike to Lagoinha do Leste, and book a controlled-access day on Ilha do Campeche for turquoise-water swimming and snorkeling. Seasons matter: summer brings warm water and busy boat schedules, while winter can deliver cleaner water but colder temps and more weather cancellations.
