Ramsau im Zillertal, Tirol, Austria
A design-led GreenHotel on a sunny Zillertal hillside above Mayrhofen, with geothermal energy, a rooftop pool, guided alpine adventures and Chef Christian Hotter's coolinary kitchen.









Green facades thick with alpine herbs wrap Coolnest's exterior. The heated rooftop pool looks straight across to the Zillertal peaks above Mayrhofen. Rooms are called nests. The restaurant is coolinary. The spa is the wellnest. Even the language tells you this place was built around a single idea, not assembled from parts.
Sustainability is not an add-on here. Geothermal probes supply over half the energy. Glass bottles replace plastic. Zillertal farmers deliver eggs, bread and vegetables directly. Free e-scooters sit at the door from May to October, connecting guests to Mayrhofen and Zell am Ziller without a car. A weekly programme stitches it together: sunrise hikes with Nili, sound healing with Nicole, yogilates with Joyce. Coolnest calls it modern lifestyle in the mountains. It feels like a small community built on conscious togetherness.
A guided weekly programme runs through every stay. Nili leads the sunrise hike at 04:00, returning by 08:30 with views over the entire valley. The e-bike tour to Grune Wand Hutte takes half a day. Hikes reach Keilkeller waterfall and the summit of Gerlosstein. Bike & Hike Sonnalm combines both in one outing.
Forest bathing in the Glocke nature park slows the pace. The Hippach Herb Garden walk focuses on alpine plants and local knowledge. Inside, the YogiNest hosts breathwork with Stefan, restorative yoga with Delfi, and Qi Gong sessions. Sound healing with Nicole and incense meditation with Dani fill the evening schedule. Free e-scooters reach Mayrhofen and Zell am Ziller from May to October. NOX Cycles e-mountain bikes rent at a reduced rate.

Tweets Rooftop Restaurant sits at the top of the building, open to the Zillertal panorama. Chef Christian Hotter leads the kitchen. His approach is what Coolnest calls coolinary, a word that captures the style: Tyrolean roots, creative technique, regional sourcing.
Eggs, farmhouse bread, fruit and vegetables arrive from Zillertal farms. Herbs come from the hotel's own garden. Drinks are served in glass bottles. Mornings start with a local breakfast buffet. Afternoons bring a snack service. The TOGETHER Dining evenings pair a multi-course meal with DJ Andy on the turntables, priced at 65 euros per person. It is social dining with a point of view.
The wellnest spreads across multiple levels. Panorama saunas face the mountain ridge. An alpine herb steam bath fills the air with local botanicals. The heated rooftop pool opens at 07:00 daily, and a separate adults-only relax pool runs until 21:00. Ladies Only sauna sessions hold space on Tuesdays and Saturdays.
The Beauty Nest handles bodywork. Treatments range from a 25-minute foot reflex massage to a 75-minute hot stone session and the traditional Lomi Lomi Nui. The Zwitscherstube lounge serves as the post-sauna refreshment area. Upstairs, the Panorama Nest offers quiet recline with valley views. The YogiNest hosts daily sessions, from restorative yoga with Delfi to sound healing with Nicole. All wellnest facilities are included in every stay.
Coolnest calls itself a GreenHotel, and the label runs deeper than marketing. The founding philosophy is direct: acting sustainably means acting as if we were on this earth to stay forever. Energy, food, mobility and materials all follow this line.
Geothermal probes supply more than half the hotel's energy, cutting CO2 by 115 tonnes per year. A photovoltaic system adds solar power on top. Drinks come in glass bottles. Vegan organic cosmetics fill refillable containers in every nest. Zillertal farmers deliver produce directly. Green facades and planted roofs grow alpine herbs and native flowers. Free e-scooters replace car trips from May to October, and e-charging stations serve guests who drive electric. A free Travel Green Package rewards arrivals by public transport.
Timber and clean lines on the sunny side of the Zillertal, with private terraces looking out to the Alps. A single room category — the Cool Nest, a 31 m² double — keeps things straightforward.
