The day begins in the dry interior of Neuquén and ends in the Andes — a short drive in distance, a long one in landscape. The steppe gives way to the cordillera gradually, and by the time the road drops into San Martín de los Andes, the air has changed and so has everything else.
Leaving the Steppe
The day leaves Zapala at 9:00 am. The RN40 heading southwest leaves behind the low basalt plateaus and xerophytic scrub of the central steppe and begins the long transition toward the cordillera. The landscape shifts from arid to something greener and more complicated as the road gains altitude and the Andes begin to make themselves known on the horizon.
Mirador Volcán Lanín
About two hours after departure, just off the RN40 on Ruta Provincial 61, the Mirador Volcán Lanín opens up on the left. The volcano itself rises to 3,776 metres (12,388 feet) on the Argentine-Chilean border, the centrepiece of Parque Nacional Lanín — a near-perfect snow-capped stratovolcano whose symmetry is visible on clear days from well out on the steppe. The Mapuche name carries several possible meanings, among them "died of a surfeit" or "dead rock"; Mapuche communities consider the volcano a sacred site and have traditionally declined to ascend it. The mirador was built by the provincial road authority as part of the RP61 paving project, and offers a clean, unhurried look at the cone from the roadside without requiring a full detour into the national park.
Back on the RN40 and continuing southwest, the road reaches Junín de los Andes about twenty minutes further on.
Junín de los Andes
Junín de los Andes is the oldest town in Neuquén province, founded in 1883 as a military fort during the Conquista del Desierto and formalised as a municipality in 1945 — two years after San Martín de los Andes to the south, though it predates it by fifteen years. It sits on the Río Chimehuín, and the town's identity has long been shaped by two things: the Mapuche presence in the surrounding countryside, and trout. The Chimehuín is one of the most storied fly-fishing rivers in Patagonia, and the town bills itself accordingly as the national trout capital. The fishing season runs November through April.
The church on the plaza, Parroquia Nuestra Señora de las Nieves, holds an altar resting on four stones from Lago Huechulafquen and is decorated with Mapuche looms — a deliberate fusion of Catholic and indigenous iconography. The town is also a pilgrimage point for the Blessed Laura Vicuña, a Chilean girl who lived here briefly in 1904 and died at thirteen; the sanctuary bearing her name sits near the church. Overlooking everything from the Cerro de la Cruz is the Vía Christi, an outdoor sculptural trail depicting scenes from the life of Jesus in a style that draws on pre-Columbian and Mapuche visual traditions — worth a brief look if there's time before or after lunch. Fuel at the YPF before heading to the table.
Ruca Hueney
Ruca Hueney has been on the corner of Coronel Suárez and Padre Milanesio, facing the Plaza San Martín, since 1967 — opened by Nicolás and Pepa Buamscha, Lebanese immigrants whose family still runs the place. The menu reflects the layered history of the town: regional Patagonian dishes alongside Middle Eastern staples that have been on the menu from the beginning. Trout comes in multiple preparations — smoked as an entrée, or trucha a la manteca negra as a long-standing house favourite. Venison (ciervo) is the other specialty, often served with wild mushrooms or cranberry sauce. The Arabic dishes — kepe, sfija, stuffed grape leaves — are worth ordering alongside rather than skipping for the grills.
Arrival: San Martín de los Andes
San Martín de los Andes arrives in early afternoon, the road descending through forest and a series of roundabouts on the Cuesta de los Andes before flattening onto the main access avenue into town.
The town was founded on 4 February 1898 by Colonel Celestino Pérez under orders from General Rudecindo Roca, after an agreement with the local Pehuenche cacique Curruhuinca — the last of the Patagonian towns established during the Conquista del Desierto. Its early economy rested on logging, farming, and supplying the military garrison; the European settlers who followed — Dutch sawmill operators, Syrian-Lebanese merchants, Swiss and French farmers — mostly arrived via Chile, the Argentine interior being too remote to reach easily. The creation of Parque Nacional Lanín in 1937 ended commercial logging within the park and redirected the town toward tourism.
Municipal ordinances regulate building heights and facade materials throughout the centre, requiring the wood and stone finishes that give the town its deliberately alpine character — a policy dating to the national parks era and architect Alejandro Bustillo's influence on the region's built landscape. The main commercial street runs parallel to the lake a block inland; the intendencia building facing the water serves as the Lanín National Park administration headquarters.
For camping, the closest lakeside options are Camping Catritre and Camping Lolen, both on the shore of Lago Lácar about four to five kilometres from the centre along the Ruta de los Siete Lagos. Catritre is the older of the two, with a long beach and a restaurant deck overlooking the water; Lolen is just across a stream with similar services and a handful of cabins as well. The ACA (Automóvil Club Argentino) campsite is an option if something closer to the centre is needed — shaded plots near a stream on the edge of town — but the lakefront sites are worth the short drive.
The afternoon is well spent on the waterfront. The costanera runs the length of town along Lago Lácar, and from the main pier the navigation company runs excursions to Quila Quina — a sheltered cove on the far side of the lake, 18 km by water, with beaches, forest walks, and a Mapuche community. The boat takes about an hour each way and departs from the dock on the costanera. Closer to hand, La Islita is a small wooded beach a few kilometres along the northern lakeshore, reachable by road or on foot, with clear water and a small island just offshore.
