Junín de los Andes proudly holds the title of Argentina's Trout Fishing Capital, and spring is when the town truly comes into its own. Located in Neuquén province at the foot of the majestic Lanín Volcano (3,776 m), this quiet town on the banks of the Chimehuin River is the gateway to some of the finest fly fishing waters in South America.

Spring from September to November builds anticipation toward the fishing season opening in November. The Chimehuin, Malleo, and Aluminé rivers — all within easy driving distance — begin their annual transformation as snowmelt feeds crystal-clear waters over gravel beds perfect for trout habitat. Rainbow trout, brown trout, and brook trout grow fat in these nutrient-rich waters, and the spring emergence of aquatic insects triggers the surface feeding that fly fishers dream about.

Beyond fishing, Junín offers deep cultural experiences. The town has significant Mapuche heritage, visible in the Vía Christi sculpture park that blends Christian and Mapuche imagery, in community visits, and in local crafts and cuisine. Lanín National Park provides spectacular hiking with its Araucaria forests, volcanic lakes, and of course the perfect cone of Lanín Volcano itself. Spring wildflowers create stunning displays, particularly in the transition zone between the Andes forests and the Patagonian steppe. Self-driving from Bariloche or San Martín de los Andes offers scenic routes through the heart of the Lake District.
