Mountain Lakes & Swimming in the Zillertal – Turquoise Water Between the Peaks

When the snowmelt is over and the alpine meadows glow in lush green, the Zillertal shows its most refreshing side: hidden mountain lakes mirror the peaks, and on warm summer days the turquoise water invites you to take the plunge. Around Zell am Ziller you'll find some of the most beautiful lakes in Tyrol – some just a short hike away, others easily reached by car or cable car.

The most beautiful mountain lakes around Zell am Ziller

The Zillergründl reservoir, high above Mayrhofen, impresses with its mighty dam and water that shifts from deep blue to emerald green depending on the light. If you prefer something more untouched, hike to the Stillup reservoir or the small alpine lakes in the Zillertal Alps Nature Park. Down in the valley, the bathing lake in Uderns is a popular spot for relaxed summer days – with a sunbathing lawn, crystal-clear water and views of the surrounding mountains.

💡 Insider tip: You'll catch the most beautiful light early in the morning, when the lakes are still mirror-smooth and the peaks glow in the first sunlight – perfect for a photo before the first hikers arrive.

Swimming fun for the whole family

Not every mountain lake is made for swimming – the water of the high-alpine lakes stays cool all year round. For a real bathing experience, head to the managed lakes in the valley or the region's adventure pools. Families with children will find shallow shore areas, playgrounds and cosy spots for a picnic. And after a swim, an alpine hut beckons with Kaiserschmarrn and fresh buttermilk.

"There's no finer moment than the first jump into a mountain lake – cold, clear and unforgettable."
