The Ottohaus is a mountain hut located at 1,644 meters above sea level on the Raxalpe. It offers a natural setting ideal for overnight stays, accessible after a short walk from the Rax cable car station. The hut features 18 rooms catering to different needs and offers hearty homemade cuisine, including vegetarian and vegan options. Guests can enjoy the tranquility and the clear night skies, famous for star-gazing, in the remote and untouched landscape that once inspired figures like Sigmund Freud and Viktor Frankl. Beneath the Ottohaus, visitors can explore the Alpengarten Rax, a 4,000-square-meter area with around 200 alpine plants, open during summer and autumn. The hut's history dates back to 1893 and features renovations and expansions over the years, making it a notable destination for those seeking a peaceful retreat in the mountains.
