Atlantic Forest South-East Reserves

Inscribed as a UNESCO World Heritage site in 1999, the Atlantic Forest South-East Reserves (known locally as the Reservas da Mata Atlântica do Sudeste) represent one of the most vital, biodiverse, and critically threatened ecosystems on Earth. Stretching across the Brazilian states of São Paulo and Paraná, this UNESCO site encompasses 25 individual protected areas totaling over 470,000 hectares. It preserves the largest intact contiguous swath of Brazil's original Atlantic Forest—a lush coastal biome that once stretched thousands of kilometers along the South American coastline.

While the neighboring Amazon Rainforest often dominates global environmental headlines, the Atlantic Forest contains an even higher concentration of biodiversity per hectare and an extraordinary rate of endemism. Over 50% of its tree species and up to 80% of its non-flying mammals are found nowhere else on the planet. The South-East Reserves act as a evolutionary lifeboat for world-renowned endangered species, including the Southern Muriqui (the largest primate in the Americas), the elusive Jaguar (Panthera onca), the Golden-faced Lion Tamarin, and hundreds of rare bird species such as the Red-tailed Amazon Parrot.

Geologically and topographically, the reserve system is a spectacular tapestry of landscapes. It spans dramatic coastal mountain ranges (the Serra do Mar), expansive mangrove estuaries (the Lagamar complex), pristine island archipelagos, and the dense, cavernous karst limestone valleys of the Alto Ribeira River State Park (PETAR). UNESCO designated this network as a World Heritage site not only for its incomparable biological richness, but also to protect the evolutionary processes that have unfolded here over millions of years. Visiting this region offers travelers a rare, humbling window into ancient South America before modern development reduced the broader Atlantic Forest to less than 12% of its original footprint.

Because the Atlantic Forest South-East Reserves consist of multiple state and national parks spread across two states, admission prices, operational logistics, and ticketing systems vary depending on which core reserve you explore. In 2026, conservation management has digitized ticket booking systems across São Paulo and Paraná, though cash remains essential for local guide services and island water taxis.

Capturing the dramatic landscapes of the Atlantic Forest South-East Reserves requires preparation for wet conditions, deep canopy shade, and dark subterranean spaces. Here are the top photo locations and insider strategies for an unforgettable expedition:

Top Photography Locations

• ✦
  Santana Cave (Caverna Santana - PETAR): Renowned for its enormous, cathedral-like chambers, ancient curtain formations, and the stunning Sal Travel Budgetão das Flores (Flower Hall). Use a tripod and long exposure (where permitted by your guide) to capture the natural glow of calcite formations under LED illumination.
• ✦
  Revoada dos Papagaios (Superagüi Island): Every afternoon at sunset, head to the shoreline near Ilha da Pinha to photograph thousands of vibrant Red-tailed Amazon Parrots returning en masse to roost in the mangrove canopy against a backdrop of golden twilight over the ocean.
• ✦
  Meu Rei Waterfall (Cachoeira do Meu Rei - PETAR): A towering jungle waterfall cascading into a crystal-clear emerald swimming hole surrounded by ancient tree ferns. Ideal for slow-shutter water movement shots using a neutral density (ND) filter.
• ✦
  Marujá Beach (Ilha do Cardoso): A pristine, 18-kilometer stretch of completely undeveloped beach where dense Atlantic Forest mountain ridge meets the roaring Atlantic Ocean. Perfect for dramatic coastal landscape shots.

Insider Visit Hacks

• ✦
  Optimal Seasonal Timing: The ideal months to visit are May through September (The Dry Winter Season). Rain levels drop significantly, lowering humidity and reducing mud on forest trails. Crucially, dry weather minimizes the risk of flash floods inside PETAR’s river caves, ensuring all major cave networks remain open. Summer (December to March) brings intense heat, high humidity, heavy afternoon rain, and frequent cave closures due to rising water levels.
• ✦
  Mandatory Cave Attire: Park regulations strictly enforce footwear and clothing standards. You must wear long trousers (quick-dry synthetic hiking pants are ideal) and closed-toe sturdy footwear (high-grip neoprene boots or broken-in waterproof hiking shoes). Shorts, sandals, and flip-flops are strictly forbidden inside the caves.
• ✦
  Packing Essentials: Bring a high-lumen waterproof headlamp (minimum 300+ lumens) with spare batteries, dry bags for camera gear during river crossings and boat rides, bio-degradable eco-friendly bug spray (containing Icaridin/Picaridin), and a compact microfiber towel.
• ✦
  Cash is King: Credit card readers frequently fail in deep valleys and isolated islands due to spotty cell service. Always carry sufficient cash in small denominations (BRL) to pay local monitors, boat captains, and rural eateries.

To experience both the subterranean caves and the pristine coastal islands of the Atlantic Forest South-East Reserves, visitors typically base themselves in Bairro das Serras / Iporanga (for PETAR) or Cananéia / Superagüi Island (for coastal ecosystems).
