Dique La Ciénaga is a reservoir located in the El Carmen department of Jujuy province, Argentina, sitting at an elevation of 1,186 meters above sea level. It lies approximately 33.7 kilometers from San Salvador de Jujuy and is accessed via Ruta Nacional 9 (RN9), near Villa El Carmen. The road along RN9 is winding and narrow, so drivers should exercise caution on the approach. Parking is available near the recreational areas.

The reservoir supports active paddling, with kayak sales and rentals available locally through El Carmen Kayak (reachable via WhatsApp at 388 4538929). The site has hosted competitive canoe racing events, including rounds of the NOA regional canoe championship and a Regata Pachamama event, indicating that the water is suitable for both recreational and competitive paddling. The Club Náutico La Ciénaga operates at the reservoir and provides facilities including fishing boats, a swimming pool, an inn, and viewing balconies.

Summer temperatures in the area range between 20°C and 30°C. The reservoir is also a birdwatching location, and the surrounding landscape offers mountain views characteristic of the Jujuy region.

Access to the natural areas and the dam itself is generally free, though specific facilities such as restaurants or camping areas may charge separately. Direct public transport to the site is limited, making private vehicle or organized tour the most practical options for reaching the reservoir.

The area carries historical significance as a supply point for troops under General Güemes during Argentina's independence campaigns, with Colonel Arias's forces using the locality to support General Manuel Belgrano's Northern Army Campaign. The surrounding Villa El Carmen is known for tobacco cultivation, vineyards, and a regional winery. Weekday mornings are the quieter time to visit, with lower crowd levels compared to weekends.
