A short day by distance, but the one that matters most on paper — the crossing out of Chile and into Peru, the fifth and final country of the trip. The physical drive is barely two hours; nearly all of the day's time goes to the border itself.

To the Border

The 8:00 am departure from Arica heads north on Ruta 5, fuel at the Shell station on the way out of the city before the road runs the short distance to the frontier. This is the last stretch of Chilean pavement after weeks spent moving back and forth across the Argentina–Chile border — the Andes crossed twice over since Santiago, first east into the Calchaquí Valleys and back west again at Jama — and now, finally, a border that doesn't lead back to Argentina.

Complejo Fronterizo Santa Rosa

The crossing here is an integrated one, similar in principle to Jama — Chilean exit and Peruvian entry formalities are handled at a single complex on the Peruvian side, avoiding the need to process separately at two distant posts. Chacalluta-Santa Rosa is one of the busiest border crossings on the entire Pan-American Highway, the primary land link between Chile and Peru and, by extension, the rest of the continent to the north — the volume of cargo trucks and buses passing through on any given day reflects that status. The facility has operated 24 hours a day since 2024, a return to pre-pandemic conditions after a period of restricted hours.

Because the TR4 carries Brazilian plates, the exit process involves presenting and closing out the temporary admission document issued when it first entered Chile. On the Peruvian side, the process is a fresh entry — the DICTA temporary vehicle import is completed at the same complex, and Peru's mandatory SOAT insurance, required for any vehicle circulating in the country, is purchased either at a counter in the complex or, preferably, in advance online, priced according to the length of the planned stay. None of this is unusual for overland travel in South America, but it takes time, and the two-hour window in the schedule here is exactly that — time, not distance.

Arrival: Tacna

Tacna carries its history closer to the surface than most Peruvian cities. Ceded to Chile after the War of the Pacific in 1883, it remained under Chilean administration for nearly fifty years — the postponed plebiscite promised in the Treaty of Ancón never took place — until a 1929 agreement returned Tacna to Peru. The city has worn the title Ciudad Heroica since 1821, originally for its role in the independence movement, but the nickname took on deeper resonance through the decades of occupation and the eventual reincorporation, and Tacna's civic identity today is built substantially around that memory.

The clearest expression of it stands in the Paseo Cívico at the centre of town: the Arco Parabólico, an 18-metre monument of rose-coloured stone quarried from the nearby Cerro Intiorko, raised in 1957 to honour Colonel Francisco Bolognesi and Admiral Miguel Grau, the two most venerated figures of the Peruvian side of the War of the Pacific. Every Sunday a votive lamp at its base is lit in a small ceremony repeating Bolognesi's famous vow to fight "hasta quemar el último cartucho" — to the last cartridge — and the arch is illuminated more elaborately each 28 August, the anniversary of Tacna's return to Peru. A few steps away, the Catedral de Tacna, built from the same rose-hued stone, closes out the square, and the ornamental fountain in the adjacent Plaza de Armas — designed by the French sculptor Mathurin Moreau and shipped from Brussels via the Eiffel company in 1869 — has stood through every change of flag the city has seen since.

After the length of the border crossing, the rest of the day is for settling into the first Peruvian town of the trip — the plaza is an easy walk from most central accommodation, and Tacna's restaurants, drawing on both Peruvian and the region's long-mixed culinary influences, are a reasonable place to mark the crossing into a new country.
