Campeche Island: Florianópolis’s Protected Paradise

Campeche Island sits 1.6 kilometers off Florianópolis’s southeast coast, a triangle of white sand and turquoise water that Brazil declared a National Archaeological and Landscape Monument in 2000. Since late 2025, daily visitors are capped at 800 and every person must pay a R$15 environmental fee online before boarding. That cap is strictly enforced — arrive without a ticket and you will be turned away at the pier.

The island measures roughly 1.6 kilometers long and 500 meters wide, so you can walk its main trail network in a morning. What draws people is the water: a sheltered cove on the northwest side where the sea floor is visible 10 meters down on calm days. The rest of the island is Atlantic Forest, jagged rocks, and more than 100 prehistoric petroglyphs carved into stone slabs — the densest concentration on the Brazilian coast.

Getting There and Booking Your Visit

Access is boat-only, and the rules changed significantly for the 2025/2026 summer season. You now need two separate bookings: an official visitor authorization from the Florianópolis city government website, and a boat seat with one of the licensed associations. The city ticket costs R$15 and is date-specific. Boat fares run R$150 to R$300 round trip depending on the departure point and vessel type.

Departure Points and Crossing Times

Three main departure points serve the island, each with different crossing times. From Praia da Armação, licensed artisanal fishing boats take 30 to 40 minutes. From Barra da Lagoa, speedboats cover the distance in about 30 minutes. From Praia do Campeche, the crossing is shorter — roughly 15 minutes — but the boats are smaller and more weather-dependent. I prefer Barra da Lagoa for the speedboat option because the ride is smoother and the marina has decent parking, though Armação feels more authentic with local fishermen running the boats.

Step-by-Step Booking

Go to the Prefeitura de Florianópolis website and register with your passport or CPF number. Select your visit date, choose your departure point and the association name (ABTC for Campeche, Couto de Magalhães for Armação, or the Barra da Lagoa operators), and pay the R$15 fee. You will receive a digital voucher. Then contact the association directly or book through a tour platform to reserve your boat seat. In high season (late December to early March), boats sell out days in advance — I have seen people turned away at 9 a.m. on a Tuesday in January.

What to See and Do on the Island

A day here splits naturally into three parts: the beach, the trail, and the archaeology. Most visitors spend four to five hours ashore, which is enough to do all three without rushing. The island has no restaurants or shops — bring water, food, and reef-safe sunscreen. There are basic toilets near the main beach and a small ranger station.

The Main Beach and Snorkeling

The northwest cove is the postcard: calm, shallow, and ringed by rocks that break the swell. Snorkeling is the main activity, and the water clarity is best in the morning before boat wakes and wind pick up. Bring your own mask — there is no rental on the island. The beach has no shade except for a few trees at the tree line, so a portable umbrella or a UV shirt is worth the weight. During my last visit in November, I saw three sea turtles within 50 meters of the shore, which is common in the warmer months.

The Trail to the Eastern Beaches

A 1.2-kilometer trail climbs through Atlantic Forest to the island’s eastern side, where two smaller beaches face open ocean. The path is marked but uneven, with exposed roots and a few steep sections — wear trainers, not flip-flops. The reward is near-total solitude: most day-trippers never leave the main cove. The eastern beaches have rougher surf and no shade, but the views back toward the mainland are excellent for photography in late afternoon.

The Petroglyphs

The island’s archaeological sites are its most underrated feature. Over 100 rock engravings — geometric patterns, human figures, and animal shapes — cover granite outcrops near the main beach. They date back thousands of years, left by indigenous peoples who used the island as a fishing camp. You cannot visit the engraved rocks without a licensed guide; the guides are available at the beach for around R$30 per person for a 40-minute tour. The engravings are subtle, and without a guide explaining the context, most people walk right past them.

Rules, Safety, and When to Go

The island is a protected municipal natural monument, and the rules are enforced. Do not remove sand, shells, or plants. Do not feed the coatis — the raccoon-like animals that live on the island and will absolutely try to steal your snacks if you leave your bag open. Drones are prohibited without prior authorization. Fires and camping are banned entirely; the last boat leaves at 5 p.m., and rangers check the beach to make sure no one stays behind.

Best Season and Sea Conditions

December to March brings the warmest water (24–26°C) and the most reliable calm seas, but it is also the busiest period, with the 800-person cap hit most days. April to June is my pick: water is still comfortable, the crowds thin out, and the light is softer. July to September is colder and windier — boat trips get canceled maybe two or three days a week during cold fronts. The island sometimes closes entirely between May 1 and July 10 during the mullet fishing season, when motorized transport is restricted. Check the city website before planning a winter visit.

Safety and Facilities

There are no lifeguards on the island. The main cove is calm, but currents pick up near the rocky points. Cell signal is weak to nonexistent on most of the island, so download your booking confirmation offline. The boat ride back can be bumpy in the afternoon — if you are prone to seasickness, take the morning departure and return by 3 p.m. Wear reef-safe sunscreen; the island sits within a marine protection area.

Frequently Asked Questions

Do I need to book Campeche Island in advance?

Yes. Since January 2025, every visitor must obtain a dated authorization from the Florianópolis city website and pay a R$15 environmental fee before boarding. The daily limit is 800 people, and tickets for weekends and holidays often sell out a week ahead in summer.

How long does the boat take to get to Campeche Island?

Crossing times vary by departure point: about 15 minutes from Praia do Campeche, 30 minutes from Barra da Lagoa by speedboat, and 30 to 40 minutes from Praia da Armação in traditional fishing boats.

Can I visit Campeche Island without a tour?

You can book the boat and the city authorization independently, but you cannot land without both. Boat operators require proof of the R$15 ticket at departure. The petroglyph sites, however, can only be visited with a licensed guide, available on the beach for about R$30.

What should I bring to Campeche Island?

Bring water, food, reef-safe sunscreen, and a snorkel mask — there are no shops or rentals on the island. Wear sturdy shoes if you plan to hike the 1.2-kilometer trail to the eastern beaches. Cash is useful for the guide fee, as card machines are unreliable.

Is Campeche Island closed during certain months?

As of 2026, motorized boat transport may be suspended between May 1 and July 10 during the mullet fishing season, following a recommendation from federal prosecutors. Check the Prefeitura de Florianópolis website for current restrictions before booking a winter trip.
