Due to a blockade between Copacabana, Bolivia and La Paz, I changed my planned route from going through Puno to Bolivia to going through northern Chile from Arequipa. It turned out to be a very straightforward and actually enjoyable border crossing (at least with a US passport). Northern Chile was not initially on my itinerary, but I’m glad I got to see at least a small slice of the beautiful desert beaches before heading back to the Andes.
The first step was to take a bus from Arequipa down to Tacna. I chose to go with Flores based on some recommendations from other travelers and the modest price of 25 soles, but there are many other companies that run the same route. The full schedule is posted on the left. I had no trouble getting a ticket for the 6:15 bus on a Friday morning about 15 minutes in advance.
