Into the Norte Chico
North of Pichidangui the highway keeps close to the coast before angling inland through the hills of the Choapa valley, the landscape drying out mile by mile into the scrubby, semi-arid country that marks the start of Chile's Norte Chico. This is a real transition, not a gradual one — the vineyards and pine forest of the last several days give way to a starker, browner terrain, cactus and low scrub standing in for the greenery further south.
Totoralillo
The day's real stop comes at Totoralillo, a small bay about 27 kilometers south of La Serena, sometimes nicknamed Chile's own Caribbean for the improbable clarity of its water against the surrounding desert hills. The bay is small and sheltered, backed by white sand and rocky points on either side, with water noticeably calmer and clearer than anything on the coast further south — a real swim rather than a wade, and good enough for snorkeling if there's a mask in the car. After days of cold-water coastline, this is the stop worth lingering at.
Arrival: La Serena
The final stretch north delivers La Serena by early evening, Chile's second-oldest city and the gateway to the Elqui valley beyond. The old colonial core, rebuilt in a deliberately uniform neo-colonial style in the mid-20th century, sits a little inland from the coast, while the Avenida del Mar strip along the water is where the city does its evening business — restaurants, ice cream, and a long beachfront walk. With a swim already behind you at Totoralillo, there's no pressure to find one here; the evening is free to settle into the town itself, the pisco country and dark skies of the Elqui valley waiting for the days ahead.
