Where is Portezuelo del Cajón?

Okay, picture this: you're cruising along Ruta 27, leaving San Pedro de Atacama in Chile behind you, headed towards the wild landscapes of southwestern Bolivia. You're about to cross the Portezuelo del Cajón, also known as Hito Cajón, an international border that sits way up high at 4,480m (that's nearly 14,700 feet!). This isn't just any border crossing; it's an adventure.

The whole stretch from San Pedro de Atacama to Quetena Chico is about 150 km (93 miles) of mixed terrain – expect both smooth paved sections and bumpy, unpaved bits. You're basically hugging the lower slopes of the Juriques volcano, so the scenery is out of this world. Think stunning Andean landscapes, especially as you get closer to Bolivia. On the Bolivian side, you’ll be smack-dab in the Eduardo Avaroa Andean Fauna National Reserve, with Laguna Verde and Laguna Blanca nearby. It's a super popular route for travelers going between Uyuni and San Pedro de Atacama, so you’re bound to meet fellow adventurers.

Now, heads up: the Bolivian Aduana (customs) is bizarrely located about 80 km from the actual border, in what feels like the middle of nowhere at over 5,000m! Getting there involves passing through a guarded barrier. The Chilean border post, on the other hand, is a good 40 km down the road, closer to San Pedro de Atacama. Before you set off, check the weather – high altitude can bring unpredictable conditions. Be prepared for cooler temperatures and potential storms as you climb. Enjoy the ride!
