Working-class neighborhood on the Riachuelo river, famous for the Caminito pedestrian street with its brightly painted tin houses and the Boca Juniors stadium La Bombonera. Caminito gets crowded with cruise-ship day-trippers in the morning, so go early to see it in peace. The area south of the museum is a real barrio, and Google Maps helps you avoid the streets that are not safe to walk through after dark.

City of the dead built in 1822, with ornate mausoleums, marble statues, and tree-lined avenues that look more like a small town than a graveyard. The tomb of Eva Peron is the most visited spot, and the surrounding Recoleta neighborhood is one of the nicest for walking. Mobile data works well inside the cemetery, which is useful for reading the Spanish-only plaques on the historic tombs.

Oldest barrio of Buenos Aires, with cobblestone streets, antique shops, and the Sunday Feria de San Telmo that runs along Plaza Dorrego and Defensa street. Tango dancers perform in the plaza on Sundays, and the cafes stay open late. Mobile data is reliable along the main streets, and rideshare pickups are quick at the corner of Defensa and Chile.

Modern waterfront district built on the old port reddocks, now home to glass skyscrapers, high-end restaurants, and the Reserva Ecologica Costanera Sur at the southern end. The Puente de la Mujer (Woman's Bridge) by Calatrava is the most photographed spot, and the waterfront is a long, easy walk with 4G signal the whole way.

Largest neighborhood in Buenos Aires, divided into Palermo Soho (boutiques and bars), Palermo Hollywood (restaurants and film studios), and the Bosques de Palermo park complex. The Rosedal garden, the Japanese Garden, and the lakes are a popular half-day walk. Mobile data is strong across the bars and restaurants, which is useful for calling a Cabify during a rainstorm.

Opera house on the corner of Cerrito and Tucuman, opened in 1908 and considered one of the best concert halls in the world for its acoustics. The guided tour covers the main hall, the stage, and the underground rehearsal rooms. Daytime tours are in English and Spanish, and the tour office uses WhatsApp for last-minute bookings, which works fine on the local 4G.

Provincial park that includes the south face of Aconcagua, the highest mountain in the Americas at 6,961 meters. The park entrance is at Penitentes, about 180 km from Mendoza city on Ruta 7, with the trailhead and a series of camps further up the Horcones valley. The road is paved, the entry fee is paid in cash, and mobile data works at the entrance and at the trailhead only.

Wine-producing area 20 km south of Mendoza city, with more than 20 bodegas open for tastings. The most visited are the historic Trapiche, Zuccardi, and Catena Zapata, plus smaller family-run spots. The flat roads make it easy to bike between wineries, and the local 4G is reliable at the larger bodegas and patchy at the smaller ones farther from the main road.

Ski resort 20 km from Bariloche city center, with the highest lift reaching 2,030 meters. In winter it is the main Patagonian ski area, and in summer the upper trails open for hiking with views of Nahuel Huapi and the Andes. Mobile data works at the base and the main terraces, and the snow report is updated daily on the resort's Instagram page.

Lakeside resort and ecological reserve 25 km from Bariloche, with the Llao Llao hotel as the architectural landmark. The 12-km circuit hike passes the Bahia Lopez, the Lopez camp, and the panoramic Cerro Llao Llao viewpoint. Signal is good at the trailhead and the first viewpoint, drops to 2G or nothing along the Lopez camp, and returns near the hotel. Download the offline map before starting.
