Paimún Lake: The Quiet Corner of Lanín National Park

Paimún Lake sits in the Lanín National Park, a 30-kilometer gravel drive from Junín de los Andes along Provincial Route 61. The lake is smaller and noticeably calmer than neighboring Huechulafquen, making it the better stop for anyone who wants to fish, walk a quiet shoreline, or simply look up at Lanín Volcano without a crowd.

Getting There and Getting Oriented

By Car from Junín de los Andes

The drive from Junín de los Andes takes about an hour on ripio (gravel), passing the Huechulafquen entrance booth where you pay the park fee. The road follows the north shore of Huechulafquen before cutting inland at the narrow channel known as La Unión, the short water link between the two lakes. From there, a signed spur leads to Paimún's southern shore and the small ranger station, the Seccional Paimún. The road is well maintained but dusty; a standard car is fine in dry weather.

By Bus or Organized Tour

There is no public bus to the lake itself. Most visitors join a full-day excursion from San Martín de los Andes (about 90 minutes away) or Junín de los Andes. Tours typically combine Huechulafquen and Paimún in one loop, with a stop at the Chapel of Paimún and a short walk to the shore. If you prefer to move at your own pace, rent a car in San Martín or Junín — the freedom to stop at the volcanic beaches along the way is worth the cost.

What to See and Do at Paimún Lake

Fishing for Trout

Paimún is one of Neuquén's celebrated fly-fishing lakes. Rainbow trout, brown trout, brook trout, and perch all live here, and the browns can grow large. Anglers fish from the shore and from small boats, using dry flies and nymphs in the bays and stream mouths, and streamers near the steep banks and sunken logs. A valid provincial fishing license is required; you can arrange one in Junín de los Andes before you head out. The lake sees far fewer anglers than Huechulafquen, so you can often find a quiet stretch of water even in peak season.

The Chapel of Paimún

The small Chapel of Paimún (Capilla del Paimún) stands near the lake's southern shore, a simple whitewashed building framed by araucaria trees. It is a local landmark and a common stop on guided tours. The chapel is not always open, but the exterior and the surrounding lawn make a pleasant picnic spot. Nearby, you'll often see Mapuche artisans selling woolen goods and carved wood — a good place to buy directly from local families.

Hiking and Shoreline Walks

A short trail from the Seccional Paimún ranger station leads along the shore, covering about 4.6 kilometers round trip with roughly 330 meters of cumulative elevation change. It's an easy walk, suitable for children, and gives you open views of the lake and the volcano's west face. For a longer hike, you can follow the south shore toward La Balsa and Puerto Canoa, or arrange a boat crossing to the Angostura del Paimún and continue on the 15-kilometer trail to the Epulafquen narrows. That route is considered challenging and takes 5 to 6 hours; it's best for hikers with some experience and a map.

Wildlife and Scenery

The lake is surrounded by mountains and dense forest, home to red deer, foxes, wild boar, and hares. Birders should watch for the Andean condor and the Magellanic woodpecker. The water is deep green, contrasting with Huechulafquen's blue — a difference that becomes obvious when you see the two lakes close together. The west face of Lanín Volcano (3,776 meters) dominates the view from the northern shore, especially in the early morning when the peak is clear.

Park Rules, Fees, and Practical Details

Entrance Fees and Registration

Lanín National Park charges an entrance fee at the Huechulafquen booth on Route 61. As of June 2026, foreign visitors pay ARS 35,000, Argentine residents ARS 15,000, students ARS 12,000, and Neuquén province residents ARS 8,000. The fee covers the Huechulafquen and Paimún circuit for the day. Keep your receipt — it can be useful if you leave and re-enter. Fees are adjusted periodically for inflation, so check the official Lanín National Park page before you go.

All visitors must register at the ranger station when entering the park. The registration is free and takes only a few minutes. Bring a photo ID. Dogs and drones are not allowed in the park; leave them at home. Fires are prohibited except in designated fire pits at authorized campsites.

Camping and Facilities

Camping is available at designated sites near Paimún, including the Ecufue campsite on Route 61. These are basic sites with pit toilets and fire rings; bring your own water, food, and stove. There are no shops or restaurants at the lake — the nearest services are in Junín de los Andes. Fuel up and buy supplies before you leave town. Cell coverage is spotty, so download offline maps or carry a GPS device.

Best Time to Visit

The park's main season runs from November through April. December to March is warmest, with daytime temperatures between 15°C and 25°C, but it is also the busiest period. November and April offer fewer visitors, cooler weather, and good fishing. Autumn (March–April) brings changing colors to the deciduous forests. Winter (June–August) can bring snow and road closures; check conditions before driving. The lake sits at about 900 meters elevation, so nights are cold even in summer — pack a warm layer.

Safety and Etiquette

The weather can change quickly. Wind is common, especially in the afternoon, and can make boating or casting difficult. Tell someone your plans if you hike beyond the main trails. There are no lifeguards; swimming is cold and not recommended. Respect Mapuche land — some areas around the lake are community property, and you should ask before crossing fences or entering marked areas. Carry out everything you bring in, including fishing line and food scraps.

Rainbow trout, brown trout, brook trout, and perch are common. Brown trout can reach notable sizes. Fly fishing is popular from shore and boat. You need a provincial fishing license, available in Junín de los Andes. The lake is less crowded than Huechulafquen, so you'll often have room to cast.
