Pertisau am Achensee is located on the western shore of Lake Achensee, directly at the foot of the Karwendel Nature Park, Austria's largest nature park and one of the most beautiful mountain hiking areas in Europe. Pertisau is home to a main landing stage for the Achensee shipping company, and the renowned Tiroler Steinöl® (Tiroler Shale Oil) is also produced there. It is extracted at the shale oil works in the Karwendel Mountains and then processed into excellent skincare products. At the Tiroler Steinöl Vitalberg (Tiroler Steinöl Vitalberg), the shale oil museum in Pertisau, visitors learn all about the extraction and processing of Tiroler Steinöl. Due to its close proximity to the Karwendel Nature Park, the town is a good starting point for wonderful hikes or mountain bike tours. There are various alpine pastures with excellent food and drink! 😋🍺

Whether from the terrace of the Erfurter Hütte or from the mountain station of the Rofanbahn, the view is magnificent.

The Rofanspitze, the third highest peak in the Rofan Mountains, is an easily accessible and popular summit destination. That is why the rocks are very greasy and therefore slippery in some places.

The Zwölferkopf is 1491 m high. Here you will find the Karwendelhaus with a good kitchen and a lovely terrace. From here you have a great panoramic view over parts of Pertisau and the entire length of Lake Achensee.

The Rofanspitze is the third highest peak in the Rofan Mountains. From up here you have a fantastic 365-degree view. The climb requires stamina and surefootedness. The climb to the summit has a gradient of around 40-45%. We saw some who had neither. We hoped that we wouldn't have to watch one of these people fall. You should also use your hands on the last stretch to hold on to the barren rock. The small plateau at the summit cross is made entirely of rock. You should be aware that you are in alpine terrain throughout the Rofan Mountains and be equipped accordingly (drinking lots, alpine shoes, hiking poles, etc. are highly recommended). From up here you can see not only the Zireiner Lake but also the Gruber Lake. This glows a beautiful turquoise color in the sunshine. On nice days it can get crowded here.

A great hut at 1834m that offers a very tasty Kaspresskndöel soup. It is even more fantastic to enjoy the food/drink on the terrace. The view of the Achensee and the mountains is breathtaking. You can also stay overnight at the hut. It offers mattress dormitories, shared rooms and twin rooms. The twin rooms are booked up very quickly, especially during the holidays. The hut is a perfect starting point for a variety of hikes and climbs in the Rofan Mountains. It is one of the few huts that is open in both winter and summer. The exact opening times depend on the weather conditions. Detailed information can be found on the homepage: https://www.erfurterhuette.at/

The Rofanspitze (2259m) is probably the most famous peak in the extremely interesting Rofan Mountains - even if it is only the third highest. Thanks to the Rofan cable car, the summit can be reached on a hike along well-marked paths. The panorama can't be beat when the weather is good and the many mountain lakes that you pass on the way up and down are great for cooling off on hot days.

For breathtaking views, consider Rofanspitze, which offers sensational views towards the Kaiser Mountains. Seebergspitze provides expansive views over Lake Achensee and the Rofan range. Bärenkopf is also highly recommended for its picture-perfect views of the entire fjord-shaped lake and the vast Karwendel mountains.
The View of Lake Achensee from Zwölferkopf is easily accessible via the Karwendel cable car from Pertisau. From the top station, you can enjoy fantastic panoramic views of the lake and surrounding mountains. The Erfurter Hut, located next to the Rofan cable car mountain station, also offers a great view down to Lake Achensee from its terrace.
Hochiss, the highest peak in the Rofan Mountains, offers a challenging yet rewarding hiking experience with a varied trail from Erfurter Hütte. The last 200 meters of ascent on Bärenkopf are steep and partially exposed, suitable for experienced hikers. Additionally, the strenuous point-to-point ridge hike connecting Seekarspitze and Seebergspitze provides a high-trail experience with impressive views.
Yes, Zwölferkopf, accessible via the Karwendel cable car, is a great option for families. From the top station, you can enjoy views and regional dishes at the Alpengasthaus. The Erfurter Hut is also categorized as family-friendly and is easily reached by the Rofan cable car, serving as a base for exploring the Rofan mountains.
The best time to hike the mountain peaks around Achen Lake is generally from late spring to early autumn (May to October). During these months, the weather is typically more stable, trails are clear of snow, and the lush meadows and clear views make for an ideal hiking experience. Some huts, like the Erfurter Hütte, are open both in summer and winter.
The region is often called the 'Tyrolean fjord' due to the lake's picturesque setting among steep mountain slopes. The Karwendel mountains, bordering the lake, are known for their rich flora and fauna and host the highest population of golden eagles in the Alps. The Rofan mountains offer diverse terrain, from gentle paths over meadows to dramatic rock faces.
Beyond hiking, the Achen Lake region is an adventure playground. You can explore cycling routes like the 'Achensee – Achen Lake loop from Pertisau' or 'Gern Alm – View of the Karwendel Valley loop from Achensee Seespitz' found in the Cycling around Achen Lake guide. Mountain biking is also popular, with trails such as 'Karwendel Three Alpine Pastures Tour' available in the MTB Trails around Achen Lake guide. The Achensee 5-Peaks Via Ferrata offers an adrenaline-pumping challenge for climbers.

The Karwendel mountains, which form the western boundary of Lake Achensee, are part of one of the largest nature conservation areas in Tyrol. They are renowned for their impressive scale, rich flora and fauna, and are home to the highest population of golden eagles in the Alps. Hikers can experience diverse landscapes, from lush meadows to rugged rock faces.
Yes, combining peaks is a popular option for more adventurous hikers. For instance, a strenuous point-to-point ridge hike connects Seekarspitze and Seebergspitze, offering a high-trail experience with continuous views of Lake Achensee. The Achensee 5-Peaks Via Ferrata also allows you to traverse multiple peaks like Haidachstellwand, Rosskopf, Spieljoch, Seekarspitze, and Hochiss.
While popular viewpoints like Zwölferkopf offer stunning vistas, exploring some of the less frequented trails or slightly off-path sections of the longer hikes can reveal more secluded spots. The ridge hike between Seekarspitze and Seebergspitze, though strenuous, offers unique perspectives away from the main cable car stations, showcasing the impressive scale of the Karwendel mountains.
