Cachi is a lovely little town located in the province of Salta in northwest Argentina. The ‘Jewel of the Calchaqui Valley’, Cachi boasts picturesque adobe (mud brick) architecture, spectacular highland scenery and popular local vineyards. While there are some lovely walks in and around Cachi, as well as horse riding opportunities, don’t miss the chance to take a day trip to the Parque Nacional Los Cardones, located just 40 kilometres away. This incredible National Park is home to rugged desert landscapes, towering cacti and interesting, colourful rock formations. Guided tours of the park are available and easily organised from Cachi. Finally, another must-see natural attraction near Cachi is the Quebrada de las Flechas (Ravine of the Arrows), an astounding area of jagged, vibrantly red rocks.
