Coming from Carolina, 3km before the Inti Huasi cave, a dirt track turns off to Paso de los Reyes. From the turnoff, it’s an easy walk to La Casa de la Piedra Pintada, where more than 50 rock carvings are easily visible in the rock face. Follow the road until you reach an open meadow at the base of Cerro Sololasta and you see the new cable-and-wood walkway up the cliff face that gives you access to the site.
Once you’re finished looking at the rock art, continue up the hill for spectacular views out over the Sierras Puntanas.
The road used to be signposted, but isn't any more, making finding this place a little tricky – you can ask directions at Inti Huasi, or pay someone to guide you for a nominal fee.
