We started the next day with a wonderful, hearty breakfast served buffet-style.

There were various kinds of ham, sausages, cheese, all kinds of vegetables, breads, jams, cereals, and cake—something for every taste.

After this delicious breakfast, we took the Karwendel cable car again. Once at the top, we found the start of the “Tunnel Trail,” named for the numerous small tunnels along the path.

The first part of the hike led through a dense forest. The humidity from the previous day still lingered in the air, but the sun occasionally broke through the thick branches.

Then the path widened and crossed several lush green meadows, which serve as ski slopes in winter.

Soon the tunnels appeared—the trail’s namesake.

We were repeatedly rewarded with spectacular views of the valley and the fascinating Karwendel mountains.

Then the path narrowed again, and the forest grew thicker.

This hike was very varied. The paths were never too narrow or steep, making it very pleasant and beginner-friendly.

After more than an hour, we reached the “Rodelhütte”.

In the warm summer sun, we settled on the terrace and refreshed ourselves with ice-cold “Schiwasser” and beer.

The Rodelhütte is a very cozy, rustic hut with a wonderful view over Pertisau and the emerald-green lake.

The remaining descent from the hut to Pertisau was short and pleasant.

Since it had become sunny and pleasantly warm, we decided to continue hiking to the Gaisalm.

We first passed through Pertisau, which looked much more idyllic in the sunlight than it had yesterday in the rain.

Nestled in a lush green valley, the small village is beautifully surrounded by mountains. Pertisau lies directly on the shore of Achensee, the largest lake in Tyrol, where the hiking trail to Gaisalm begins.

The path follows the lake and leads through the most beautiful nature. The lake itself sparkles in the most stunning turquoise shades, making it unique.

This color comes from the light limestone surrounding the lake.

We crossed small bridges, enjoyed the coolness of little waterfalls, and repeatedly marveled at the lake’s wonderful panorama sparkling in the sun.

The lake lay calm and peaceful. Along the way, we met only a few other tourists, which added to the tranquility.

There are also small swimming spots along the route, but despite the sun, it was too cold to swim that day.

After about two hours of leisurely hiking, we finally reached the Gaisalm, where I had often been with my parents and siblings 40 years ago.

We found a cozy spot and got some cold drinks.

The Gaisalm is now quite a large guesthouse, especially outdoors where many guests can find space, though it has retained some of its original rustic charm.
