The Naturhotel Outside in Matrei, East Tyrol, unveiled its newly designed outdoor spa area on 25th May 2025, marking a significant step in sustainable wellness architecture. This expansion, set against the stunning backdrop of the Hohe Tauern National Park, enhances the hotel’s commitment to blending relaxation with environmental responsibility. The revamped spa, featuring an expanded natural swimming pond, wooden walkways, and biodiverse gardens, offers guests a serene escape while prioritizing ecological integrity. This development reflects broader trends in spa design, where nature, sustainability, and multisensory experiences converge to meet growing demands for regenerative travel.

The new outdoor spa area at Naturhotel Outside complements its winter renovation, which introduced a Deferegger healing water brine bath, a heated outdoor pool, and relaxation rooms crafted from local materials like East Tyrolean serpentine and larch wood. The 600,000-year-old Deferegger healing water, drawn from 1,850 metres underground, is celebrated for its therapeutic benefits, supporting skin health and respiratory function. Large panoramic windows integrate the alpine landscape into the spa, creating a seamless connection between indoors and out. The biodiverse garden, planted with native flora, supports local ecosystems, providing habitats for insects and birds while enhancing the guest experience with natural beauty.

Sustainability is at the core of Naturhotel Outside’s ethos. The hotel employs energy-efficient technologies, including photovoltaic panels that supply 20% of its energy needs and rainwater irrigation for its gardens. Local materials reduce transport emissions, and energy-optimized pool technology minimizes consumption. These efforts align with findings from Hotel Executive Magazine (July 2023), which notes a rising guest preference for “green time” to counter digital stress. The Naturhotel’s approach exemplifies how sustainable design can enhance wellness without compromising environmental responsibility.

The spa’s design also embraces multisensory principles, a growing trend in wellness architecture. Guests experience the soothing textures of wood and stone, the calming sounds of water, and the aromas of regional herbal teas. These elements draw inspiration from practices like Shinrin-yoku, or forest bathing, which studies show reduces stress hormones and promotes mental balance. The Naturhotel’s expanded natural pond and sunbathing areas invite guests to immerse themselves in the alpine environment, fostering relaxation and connection with nature.
