Discover Parque Nacional Nahuel Huapi, Argentina's oldest national park. Explore towering peaks, pristine lakes, and ancient forests around Bariloche, including Cerro Tronador and Arrayanes National Park. Essential for nature lovers and hikers.
Parque Nacional Nahuel Huapi, established in 1934, is Argentina's oldest and largest national park in the Lake District, encompassing a staggering 7,050 square kilometers. Centered around the iconic city of Bariloche, this vast protected area is a mosaic of snow-capped mountains, sprawling glacial lakes, dense Patagonian forests, and diverse wildlife. Its sheer size means that a rental car is not just a convenience, but often a necessity to fully explore its many breathtaking corners, from the dramatic peaks of Cerro Tronador to the tranquil shores of Lago Gutiérrez and the unique Bosque de Arrayanes.
This incredible park offers a diverse range of activities for every type of traveler. Hikers can embark on challenging multi-day treks to mountain refugios, while those seeking more relaxed experiences can enjoy scenic drives, boat tours across the majestic Nahuel Huapi Lake, or short walks to stunning waterfalls. However, the park's extensive network of trails and access points can be confusing, and remote areas often require navigating unpaved roads. Planning your itinerary, especially when relying on a vehicle, is key to making the most of this Patagonian gem, ensuring you experience its unparalleled natural beauty away from the more crowded zones near Bariloche.
Everything you need to plan your trip
Witness the 'Thundering Mountain' on a full-day trip. Tronador is an extinct stratovolcano straddling the Chile-Argentina border, famous for its seven glaciers and the thundering sound of ice falling. At its base, visit the Ventisquero Negro (Black Glacier), a unique dirty glacier fed by the Manso River.
Challenge yourself with a rewarding hike to Refugio Frey. This iconic trek leads you through ancient lenga forests and past granite spires to a stunning mountain hut nestled by Laguna Toncek, offering incredible views and a true Patagonian wilderness experience. It can be done as a strenuous day hike or an overnight trip.
Embark on a captivating boat tour across Lago Nahuel Huapi to Isla Victoria, then continue to the enchanting Bosque de Arrayanes. This unique forest features cinnamon-colored myrtle trees, some over 300 years old, creating a magical, fairytale-like atmosphere that inspired Disney's Bambi.
Drive a scenic route, much of it gravel, to reach the impressive Cascada de los Alerces. This powerful waterfall plunges into a pristine river, surrounded by a forest of ancient Alerces trees, some of the oldest living species on Earth. It's a fantastic spot for a picnic and short walk.
Take a leisurely drive along the iconic Circuito Chico, a 60-kilometer loop starting from Bariloche. This route offers numerous viewpoints, artisanal shops, and access to short hikes and beautiful beaches, showcasing the classic Bariloche landscape with minimal effort. It's perfect for a half-day exploration.
Enjoy the serene beauty of Lago Gutiérrez, a tranquil lake just south of Bariloche. Accessible by a paved road, it offers opportunities for kayaking, fishing, and hiking along its shores to spots like Playa Blanca, where you can relax by its clear, emerald waters.
