The History of MaresiasTur: Adventure Tourism by People Who Live Maresias
By MaresiasTur · · Updated on · 4 min read
Quick answer
The history of MaresiasTur begins in 2016 in Maresias, São Sebastião (SP), when extreme sports athlete Thiago Bertassoni and tour guide Fabrício Barboza founded an adventure tourism agency. Today it runs hikes, rappelling, boat tours and try-scuba-diving.

The history of MaresiasTur begins in 2016, in Maresias, on the North Coast of São Paulo. São Sebastião had plenty of trails, waterfalls, headlands and islands, but was missing a company specialized in adventure tourism, capable of taking visitors to those places with technique, safety and professional guidance. That was the gap the two founders set out to fill.
Today, MaresiasTur Receptivo & Ecoturismo is a ground-handling agency that takes visitors to the islands of São Sebastião's South Coast, to the waterfalls and lookouts of the Atlantic Forest, and beneath the sea, with a licensed team and a commitment to nature.
Who founded MaresiasTur?
The agency was created by extreme sports athlete Thiago Bertassoni and tour guide Fabrício Barboza. That combination still sums up the agency's approach today: the hands-on experience of someone who lives for heights, trails and the sea, paired with the knowledge of someone who guides visitors and tells the region's story.
How did the agency start, in 2016?
The first tours were hikes and rappelling, activities where technique and equipment make all the difference. Rappelling remains one of the agency's signatures:
- Lookout Rappelling: 10 meters high, with up to 2 descents, on the Trilha dos Mirantes, between Paúba and Maresias. The hike is 2 km, easy level, and the activity includes a licensed guide, all gear and individual insurance.
- Calhetas Rappelling: 96 meters at the Cachoeira de Calhetas, with licensed adventure tourism guides, leaving from the agency.
- Cachoeira das 7 Quedas waterfall hike: 2 km round trip through the Atlantic Forest, with a licensed ecotourism guide.
From a duo to a team
What started with two partners grew into a team with administrative staff, a call center and guides. The agency is located at Av. Francisco Loup, 500, in Maresias, the departure point for several tours, and the company is registered as MaresiasTur Receptivo & Ecoturismo LTDA, tax ID (CNPJ) 35.417.415/0001-40.
- Licensed guides and licensed boat captains.
- Registered with Cadastur, Brazil's Ministry of Tourism.
- Online bookings with WhatsApp confirmation and human support before and after the tour.

Why does MaresiasTur plant native saplings?
An ecotourism agency needs to give something back to the nature it shows off. As an official partner of São Sebastião City Hall's E-LIXO program, MaresiasTur trades e-waste for native Atlantic Forest saplings and has been planting every month for more than 5 years, totaling over 2,000 saplings. Learn more in how the E-LIXO program works.
