Known as the “White City,” Arequipa stands out for its colonial architecture built from sillar, a white volcanic stone. The Plaza de Armas is the city’s hub, with its impressive Cathedral and colonial buildings. The Santa Catalina Monastery, a small “town” within the city, provides a fascinating glimpse into colonial religious life. Arequipa is also the base for exploring the Colca Canyon, one of the deepest canyons in the world, where you can see the majestic Andean condor in its natural habitat.
