Reinero Saonarotonda Arvaolia Trail

The trail referred to as the Reinero Saonarotonda Arvaolia Trail is widely known as the Dientes de Navarino Circuit, located on Navarino Island in Chilean Tierra del Fuego. It is renowned as the world's southernmost trekking trail, offering an unparalleled remote wilderness experience.

This trek is considered challenging and is not for beginners. It requires good physical condition and the ability to be self-sufficient in a remote wilderness setting. The terrain is highly varied and irregular, featuring steep slopes, loose rocks, and potential snow, especially at higher points like Paso Virginia.

The Dientes de Navarino Circuit spans roughly 33 miles (approximately 53 kilometers) and typically takes between three to five days to complete. The exact duration depends on your pace, experience, and the challenging weather conditions.

The best time to hike is during the Patagonian summer, generally from December to March. It is strongly advised not to hike between May and August due to harsh winter conditions, heavy snowfall, and extreme unpredictability.

The trail offers incredibly diverse scenery, wrapping around the 'tooth-like' peaks of the Dientes de Navarino mountain range. You'll encounter jagged peaks, serene lakes, lush lenga forests, beaver ponds, streams, and cliffs. From points like Cerro Bandera, you can enjoy stunning views of the Beagle Channel, and if weather permits, even glimpse Cape Horn.

Given the trail's remote, pristine wilderness environment and its location within a sensitive ecosystem, it is generally not recommended or permitted to bring dogs on the Dientes de Navarino Circuit to protect local wildlife and maintain the trail's integrity. Always check with local authorities for the most current regulations.

While there isn't a formal permit system or entrance fee for the Dientes de Navarino Circuit itself, it is highly recommended to notify local police in Puerto Williams before and after your trek, especially if you are hiking without a guide. This is a crucial safety measure due to the trail's wild and remote nature.

The Dientes de Navarino Circuit typically starts and ends near Puerto Williams on Navarino Island. As it's a remote trek, there isn't a designated parking lot in the traditional sense. Hikers usually arrange transport to the trailhead from Puerto Williams. Being self-sufficient is key, as there are no accommodations or services along the route.

Due to the extreme and unpredictable subantarctic climate, you must be prepared for all conditions. Essential gear includes a sturdy tent, a warm sleeping bag, a reliable map, compass, and GPS, and all your food and cooking supplies. Layered clothing, waterproof and windproof outer shells, and appropriate footwear are critical. Be ready for sudden changes in weather, including sun, rain, snow, and fierce winds.

The Reinero Saonarotonda Arvaolia Trail, or Dientes de Navarino Circuit, is a unique, self-contained route. However, the komoot route itself also passes through sections of the Sentiero Reinero Saonarotonda Arvaolia (71%), Percorsi - Tappa 12 (54%), Percorsi - Tappa 11 (11%), and Strada Napoleonica (18%).

Absolutely. The entire circuit is a series of breathtaking viewpoints. Key highlights include the 'tooth-like' peaks themselves, the numerous pristine lakes reflecting the Patagonian skies, and panoramic vistas of the Beagle Channel from high points like Cerro Bandera. If conditions are clear, you might even catch a glimpse of Cape Horn, the southernmost tip of the Americas.
