Península Llao Llao, Lake peninsula in Nahuel Huapi National Park, Río Negro, Argentina

Península Llao Llao is a landform wedged between Lake Nahuel Huapi and Lake Moreno, shaped by rolling terrain and dense forests of cypress and coihue trees. The varied elevations across the peninsula create different vantage points overlooking the water bodies.

Before European arrival, the peninsula and its surroundings were inhabited by the Mapuche. Today the land is occupied by the small village of Llao Llao and by several estancias and private properties. The Llao Llao hotel, known internationally, stands within the peninsula, and the San Eduardo chapel occupies its centre.

The chapel is named San Eduardo and stands at the centre of the peninsula, near the Llao Llao hotel. It is a regional architectural landmark, and its setting draws visitors travelling the Circuito Chico and boat excursions leaving from Puerto Pañuelo.

This place is accessible by public bus from nearby Bariloche and can be explored on foot through various trails and paths. Sturdy footwear is recommended since the hilly terrain and forest routes require good footing.

The peninsula's forests shelter native huillín, huemul, pudú and red fox, alongside wild boar, hares and red deer that Europeans introduced during the 20th century. The 1,200-hectare landform separates Lake Nahuel Huapi from Lake Moreno and rises only to small hills under 300 m, the highest being Cerro Llao Llao.
