Río Baker, Aysén, Chilean Patagonia · Chile
The Baker is Chile's biggest river by volume, and it looks the part: an impossible glacial turquoise, fed from Lago Bertrand and ultimately the Northern Patagonian Ice Field, surging through lenga forest and bare granite. Over seven days you descend it by packraft, portaging the unrunnable cataracts and riding the friendly wave trains between them, camping above water so blue it photographs like a lie. The image everyone carries home is the Neff confluence, where the silt-grey Río Neff slams into the Baker's turquoise and the two colours run side by side, unmixed, below a thundering cascade. Downstream the valley opens to Caleta Tortel, a roadless village of cypress boardwalks where the river braids into fjord country — as good a finish line as paddling owns. The access town is Cochrane, a day's bus from Balmaceda airport; guided descents with rafts, drysuits and support vehicle run around £2,300. The variables are Patagonian: wind arrives without appointment and can pin boats to the bank for an afternoon, and the water hovers near 8C, so a swim is serious even on easy sections. December to March gives settled weather; November trades stability for empty campsites.
