Top Hiking Trails and Nature Reserves in Southern Brazil 2026
If you're an adventure seeker with a passion for pristine landscapes and untouched wilderness, southern Brazil is calling your name. While most travelers flock to Rio's famous beaches and the Amazon rainforest, they're missing out on some of the most spectacular hiking trails and nature reserves that South America has to offer. The southern region delivers dramatic mountain ranges, Atlantic Forest biodiversity, hidden waterfalls, and trails that'll make your Instagram followers seriously jealous—all without the overwhelming crowds you'd find up north.
Here's the thing about southern Brazil: it's the region that combines the raw beauty of nature with a more temperate climate, making it perfect for serious hikers and casual nature lovers alike. Whether you're planning a challenging multi-day trek or a leisurely afternoon walk through pristine forests, southern Brazil has experiences that'll transform the way you think about Brazilian adventure travel.
Why Southern Brazil's Nature Reserves Stand Out
Let's be real—when people think "Brazil adventure," they picture the Amazon. But southern Brazil's nature reserves offer something equally compelling: accessibility paired with incredible biodiversity. You've got the Atlantic Forest, a UNESCO World Heritage site that's more biodiverse per square kilometer than the Amazon itself. You've got canyons that rival Colorado's landscape. You've got mountains covered in cloud forests where the views literally take your breath away.
The region spans three states: Paraná, Santa Catarina, and Rio Grande do Sul. Each one brings its own flavor to outdoor adventure. The terrain shifts from dense subtropical forests to dramatic escarpments, from river canyons to mountain peaks. And unlike some off-the-beaten-path destinations, you're not sacrificing comfort or safety—the southern region has solid infrastructure, good roads, and plenty of lodging options ranging from budget-friendly to luxury eco-resorts.
Must-See Hiking Trails in Southern Brazil
Aparados da Serra National Park (Rio Grande do Sul & Santa Catarina)
This is the big one. Aparados da Serra features some of the most breathtaking landscapes in Brazil—towering canyon walls that drop 1,000 meters, covered in misty Atlantic Forest. The main trail here is the Canyon Trail, a moderately challenging hike that takes you along the canyon rim with views that feel almost otherworldly. Most hikers complete this in about 4-5 hours, and the payoff is absolutely worth it. Pro tip: the best time to visit is May through September when the weather is more stable and visibility is clearer. The "jeito brasileiro" of hospitality shines here—local guides are incredibly knowledgeable and genuinely enthusiastic about sharing their homeland's natural wonders.
Marumbi Trek (Paraná)
Want a serious multi-day hiking challenge? The Marumbi trek is one of Brazil's most iconic mountain trails, spanning roughly 40 kilometers along a mountain range with stunning Atlantic Forest scenery. This isn't a casual stroll—it's a proper adventure that takes 3-4 days and requires decent fitness levels. You'll sleep in rustic mountain shelters and wake up to forest sounds and misty mornings. The trail climbs through pristine forest, passes by several peaks, and offers panoramic views of the surrounding landscape. It's the kind of trek that hiking enthusiasts plan years in advance to experience.
Cachoeira Grande Trail (Santa Catarina)
If you want waterfall hiking perfection, the Cachoeira Grande trail in the Blumenau area is your destination. This is a moderate 6-kilometer round trip that leads to one of southern Brazil's most impressive waterfalls, cascading down about 40 meters into a natural pool. The trail winds through Atlantic Forest with morning bird calls as your soundtrack. The water's cool enough for swimming at the base of the falls—which feels absolutely amazing after a morning of hiking. This is the kind of hike that's challenging enough to feel rewarding but accessible enough for hikers with varying experience levels.
Pico Paraná Summit Trail (Paraná)
Standing at 1,922 meters, Pico Paraná is southern Brazil's second-highest peak. The summit trail is a day hike that's moderately strenuous, offering increasingly dramatic views as you ascend. The trail winds through different forest ecosystems—you'll experience subtropical forest at lower elevations transitioning to cloud forest as you climb. On clear days, you can see into Paraguay from the summit. The mountain's weather can be unpredictable, so go prepared with layers and a rain jacket, but that dramatic cloudscape actually adds to the mystique.
Top Nature Reserves for Wildlife and Biodiversity
Iguazu National Park (Paraná)
We know, we know—you've heard about Iguazu Falls. But beyond the famous waterfalls, the national park is a sprawling nature reserve with excellent trails through Atlantic Forest habitat. You get dual benefits: the jaw-dropping waterfall experience plus legitimate nature trails where you might spot toucans, coatis, howler monkeys, and countless bird species. The park has developed several hiking routes of varying difficulty, so you can customize your adventure level.
Araucária National Park (Paraná)
This reserve protects one of South America's rarest ecosystems: the Araucaria forest, characterized by towering Paraná pine trees that create an almost primordial landscape. The park offers several trails ranging from easy nature walks to more challenging hikes. What makes this reserve special is that you're walking through a forest type found nowhere else in the world—the biodiversity here is completely unique. Birdwatchers absolutely love this place because the Araucaria forest is home to numerous endemic bird species.
Serra Geral National Park (Santa Catarina & Rio Grande do Sul)
This park protects more Atlantic Forest and canyon systems, with trails that take you through cloud forests and along dramatic cliff edges. The Pedra Grande trail here is spectacular—a moderate hike that rewards you with views of multiple canyons and, on clear days, views toward the Atlantic Ocean in the distance. This is where you get that sense of vast wilderness that makes you feel genuinely small and insignificant in the best possible way.
Practical Tips for Hiking in Southern Brazil
Best Time to Visit
May through September is your sweet spot. Temperatures are cool but not cold, rainfall is less frequent, and visibility for those panoramic views is generally excellent. Winter (June-August) can bring occasional snow to higher elevations in the far south, which adds a unique dimension to hiking here. Avoid November through March—that's summer in the Southern Hemisphere, and the heat combined with rain makes trails muddy and potentially dangerous.
What to Pack
Layers are essential. Morning temperatures might be cool, but afternoon sun can warm things up significantly. Bring a quality rain jacket—the southern region gets more rainfall than the northeast, and mountain weather changes quickly. Good hiking boots with decent ankle support are non-negotiable for rocky terrain. Insect repellent is important in the Atlantic Forest, especially near water sources. And bring plenty of water—dehydration at elevation sneaks up on you faster than you'd expect.
Fitness Considerations
Southern Brazil hiking ranges from easy to extremely challenging. Honestly assess your fitness level. Some trails like Cachoeira Grande are accessible to people with moderate fitness. Others like Marumbi demand serious cardiovascular conditioning and mountaineering experience. There's absolutely no shame in choosing easier trails—you're still getting authentic nature immersion and breathtaking views without pushing yourself beyond safe limits.
Local Guides and Safety
Hiring a local guide genuinely enhances the experience. They know the trails intimately, can point out wildlife you'd otherwise miss, and know weather patterns and seasonal conditions. Safety-wise, trails in national parks are generally well-maintained and marked. That said, always inform someone where you're going, bring a charged phone, and start early enough that you'll finish before dark. Southern Brazil isn't wilderness in the "true survival mode" sense—help is relatively nearby—but wilderness safety principles still apply.
Beyond the Trails: Nature Reserve Experiences
Many reserves offer more than just hiking. You can do wildlife spotting tours, bird-watching expeditions, or guided nature walks with naturalists who explain the ecological relationships you're observing. Some reserves have visitor centers with excellent interpretive exhibits. The Iguazu National Park, for instance, has multiple viewpoint areas where you can experience the falls from different angles without necessarily doing full hikes. Some reserves offer nighttime guided walks where you might spot nocturnal wildlife—it's a different sensory experience entirely.
Getting There and Where to Stay
Most nature reserves are accessible from major cities: Curitiba (Paraná's capital) serves as a hub for Marumbi and Araucária parks. The town of Puerto Iguazu is your base for Iguazu Falls. For Serra Geral and Aparados da Serra, Cambará do Sul is the nearest town with accommodations. You can fly into Curitiba or Porto Alegre and rent a car for maximum flexibility. Accommodations near reserves range from budget pousadas to upscale eco-lodges where you might enjoy views from your room that rival the hiking trails themselves.
Final Thoughts: Southern Brazil Awaits
Southern Brazil's hiking trails and nature reserves represent some of the most authentic wilderness experiences in South America.

You're getting genuine adventure, real interaction with landscapes that shaped Brazilian ecology, and that incredible feeling of discovering places that haven't been commercialized into oblivion.
The region's combination of accessibility, biodiversity, and dramatic scenery makes it ideal for adventure seekers of varying experience levels.
