When I travel to Chile I have to visit Arica, I almost always look for mountain destinations and try to travel to the south of the country, but I often take a few days at the beach before leaving to adapt to the heat again, it is better in Summer to travel, the rest the water is very cold even when you are in the north and I always do the mobility by plane, it is not very expensive, saving time is enough because Arica is on the northern border with Peru, so the distance is quite a lot.
