Hiking at Lake Achensee: more wonderful than you can imagine

Once you’ve been hiking at Lake Achensee, you’ll want to come back again and again.
Here’s why: The varied landscape delights nature lovers, leisure hikers, and mountaineers alike. And it’s not just hikers that find their paradise here with us in Pertisau, but golfers are also thrilled by perfect greens and fairways.

Unforgettable holidays on Lake Achensee

In summer, there’s so much to experience around our wellness hotel on Lake Achensee. Why not take a boat trip on the 7km² lake, which is the largest in Tyrol? Fun fact: Lake Achensee is 9.4 kilometres long and at some points gets up to 133 metres deep! During a boat trip, you’ll enjoy an amazing view of the surrounding Karwendel mountain range and Brandenberg Alps. Water fans can also refresh themselves with a jump in the lake at one of the lidos or on the publicly accessible shoreline. Do you fancy more action? Then try your hand at windsurfing, stand-up paddling, canyoning, or diving! Our tip: Hire a pedal boat, explore the lake, and enjoy the warm sunshine.

Biking and hiking at Lake Achensee

In summer, there’s not just plenty going on at the lake, but countless activities also await you in the surrounding area. When hiking at Lake Achensee, you can look forward to idyllic views, impressive flora and fauna in Karwendel Nature Park, and a wide-ranging 500-kilometre network of hiking trails. In the Rofan mountain range, mountaineers can climb to their heart’s content, as there are some 250 sports climbing routes on the bizarre rock formations, nine via ferratas, and a forest high ropes course. And bike lovers? They can enjoy top conditions for exciting bike tours in the Karwendel and Rofan mountain ranges. Leisure cyclists and bike pros alike will find everything their hearts desire on over 250 kilometres of bike trails. Do you prefer to have a little more power behind your pedals? Then hire an e-bike on Lake Achensee and head out to explore! You can get even more information and tips directly at our hotel on Lake Achensee.
