Practical details and location
The property’s own website
The property's own site: its name and its place are on the page
Safely managed drinking water, Chile, 2024: The World Health Organization reports 98 per cent of the population nationally, 99 per cent in urban areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing.
Regional data is context about the location. It does not establish conditions inside a room.
Ambient PM2.5 and PM10 near Neltume, Los Ríos, Chile, 30 days to 2026-08-17: Modelled ambient air over this location averaged 1.2 micrograms per cubic metre of PM2.5 and 1.5 of PM10 across the 720 hours to 2026-08-17, peaking at 12.9 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room.

Evidence by area
All eight areas, in the order this index reads them. Every line was read and placed by a person.
Air Ecology
The reserve's frequently asked questions state that its hotels and facilities are entirely non-smoking and that smoking is prohibited inside guest rooms and in enclosed common spaces, with no filtration, ventilation or air measurement named.
In their words: “En consideración al medio ambiente y a la salud de las personas, nuestros hoteles e instalaciones son 100% no fumadores, por lo que se prohíbe fumar dentro de las habitaciones y en espacios comunes cerrados.”
Water Integrity
A 2012 report in Diario El Ranco listed, among the facilities of Hotel Nothofagus, baths set in centenarian tree trunks filled with heated natural waters, naming no water source, treatment or sanitation method.
In their words: “Además, el hotel tiene amplias salas de estar, dos comedores, un centro de convenciones para 200 personas, cancha de mini golf, bar internacional, sala de juegos para niños, lavandería, biblioteca y baños en troncos centenarios con aguas naturales climatizadas.”

Materials and Textiles
A 2012 report in Diario El Ranco on the renaming of the hotel stated that it was built from the wood of four named native species: raulí, coigüe, roble and lenga.
In their words: “Ahora se llamará "Nothofagus", la misma denominación científica que reciben los árboles con cuya madera fue construido: raulí, coigüe, roble y lenga.”

The same 2012 report described the interior ramp serving the guest rooms at Hotel Nothofagus as having railings made of mañío and raulí trunks covered with roots and lianas.
In their words: “Para acceder a las habitaciones se puede hacer uso de un ascensor o de una rampa con una suave pendiente que circula por todo el interior, como una especie de caracol, cuyas barandas de troncos de mañío y raulí están cubiertas de raíces y lianas.”

The property describes Hotel Nothofagus on its own site as a building made of noble materials, with no product, brand, grade or standard named.
In their words: “Como salido de un reino desconocido, en medio del Bosque Húmedo Templado un árbol extiende sus ramas hacia el cielo y emerge Nothofagus, maravilloso edificio hecho de materiales nobles donde se experimentan sensaciones, formas, texturas y sonidos que nos traerán de vuelta a lo natural.”
Food and Kitchen
The property states that dishes at Restaurante Nothofagus are prepared with food from the surrounding land and that its buffet draws on local gastronomy, naming no farm, supplier, share of produce or verification.
In their words: “Here, you can enjoy dishes prepared with food from this magical land, where every bite will connect you with the surrounding nature.”
The property states that its Petermann brewery and pizzeria, close to the hotel reception, makes pizzas with local ingredients including wild boar, deer, trout and salmon and serves four named artisanal beers, with no supplier, producer or sourcing verification published.
In their words: “the brewery Petermann, offers exquisite varieties of pizzas, made with local ingredients, such as wild boar meat, deer, trout and salmon, which can be accompanied by any of the four varieties of artisanal beer: Arrayanes, Piedras Negras, Pilmaiquén and Pozo de Oro.”
Biophilic and Healing Design
In a 2020 interview with Ladera Sur, the architect of the reserve's hotels, Rodrigo Verdugo, describes the connecting corridors between the hotels as deliberately set low and elevated so that guests see different strata of the forest.
In their words: “Por ejemplo, el que los pasillos de conexión entre los hoteles fueran bajos y elevados, para ver distintos estratos del bosque”

The same interview records the architect's stated intent for Montaña Mágica, a lodge conceived as a water feature from whose facades water falls and plants grow, and describes Nothofagus as connected to it by a climate controlled bridge.
In their words: “De esta forma, inmersos, entre líquenes, briófitas, hongos, olivillos y canelos, entre otros ejemplares de todo el proceso simbiótico, siguió la construcción del hotel Nothofagus, de 55 habitaciones, que se conecta por un puente climatizado desde montaña mágica.”

A 2012 report in Diario El Ranco describes Hotel Nothofagus as tree shaped, with a waterfall and an oak running up through its seven storeys inside the structure.
In their words: “Al igual que "Montaña Mágica Lodge" -el hotel con forma de montaña que está ubicado a su lado y al que está unido por una pasarela de madera- el "Nothofagus" se caracteriza por su innovadora arquitectura: tiene forma de árbol y en su interior, en la mitad de su estructura, hay una cascada de agua y junto a ella un roble que recorre sus siete pisos de altura.”

The property states that all 55 rooms at Hotel Nothofagus have a view of the Patagonian forest.
In their words: “Cuenta con 55 habitaciones con excelente vista a la Selva Patagónica, divididas en cuatro categorías: Estándar, Superior, Suite y Suite Nothofagus.”

Disclosures
Compare what each stay offers, how it was checked and what still needs confirming. Assessment labels describe the review, not an overall quality rating.
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
A score describes proof: what a stay publishes and, on a Human Garage certified stay, what our assessor checked in person. It is not a quality rating of the property. Listings are free, and any commercial relationship is disclosed.
