Avenida Diego Portales extends out of Arica’s city centre into the green AZAPA VALLEY. The far western end of the valley is, to all intents and purposes, a suburb of Arica, crammed as it is with condos and villas, some of which have been converted into trendy discos, along with a couple of good restaurants. The highlight of a trip to the Azapa Valley is the Museo Archeológico, which houses a collection of the world’s most ancient mummies. This museum is among Chile’s best and is definitely worth the trip out here. If you’re booked on a multi-day tour of the Altiplano, it’s very likely this will be a stopoff.
