Campamento Serón is a campground on the eastern side of Torres del Paine National Park, situated roughly 14 kilometers and four to five hours by trail from the Las Torres central sector.

It marks the traditional starting point of the O Circuit, the longest trekking route in the park. The approach passes through ancient lenga forests and requires crossing several rivers before reaching the site's open valley setting near Rio Paine.

The campground offers basic but functional amenities for trekkers, including a dining room, bar, bathrooms with hot showers, and covered cooking and eating areas with tables and benches. A sink is available for filling water bottles.

Wi-Fi is available for an additional fee. The site also offers a fully equipped camping option with pre-pitched tents designed for comfort and weather resistance after a long day on the trail.

From Serón, the next major leg of the O Circuit heads to Dickson Lodge, a roughly 18–19 kilometer stretch taking five to six hours, following the Paine River through open grasslands before climbing to a saddle above Lago Paine.
