In Aeugstertal, protected landscapes, trails and local history are among the area’s defining features. The upper Reppisch Valley is part of the valley; the hamlet of Müliberg connects Aeugstertal with the municipal district on Aeugsterberg. Visitors can choose from several options: nature at Lake Türlen, hikes or a visit to the Riedhof Mine.

Wetlands, lake shores and protected species

The Breiten wetland and dryland habitats are listed as a nature conservation site of supra-municipal importance; the Knonaueramt regional structure plan designates the area as a nature reserve. Its habitats include wetlands, nutrient-poor meadows and nutrient-poor pastures. They are home to protected and endangered animal and plant species. Lake Türlen, its shores and the adjoining landscapes are also protected by the canton.

The natural landscape around the lake encompasses a variety of habitats and species: more than twenty different orchid species grow in the area. The northern end of the lake has spawning grounds for grass frogs, common toads and alpine newts. These details give a walk or hike a tangible connection to nature; the protected areas and shores are more than just a backdrop.

Choose a hike by time and distance

Hikes and walks are possible around Lake Türlen. One specific longer option is the circular Lake Türlen–Aeugstertal hike: it is 19.4 kilometres long and takes about four hours and 50 minutes. Another hiking route, rated T1, goes via Müliberg and Lake Türlen; it is 10.7 kilometres long and climbs 270 metres. This gives you a choice of two different distances without assuming a walking time for the T1 route.

A route via Müliberg, Lake Türlen, Linden and Herferswil to Mettmenstetten takes just under three hours. For a broader regional perspective, the Ämtlerwäg runs for 46 kilometres through the Säuliamt. This three-day circular trail connects landscapes, nature reserves, distant views and cultural monuments; along the way, 22 information panels offer insights into the region’s culture and history. It is worth checking the route before setting out.

Summer at Lake Türlen and culture in the valley

In summer, you can swim and go boating on Lake Türlen. The Erpel restaurant is right on the lakeshore and serves seasonal and regional specialities. If you would like to combine activities with a meal, it’s a useful option to consider when planning a summer visit; the restaurant’s offerings are seasonal.

Place names also tell the story of the valley. The name “Chloster” points to the former site of a community of Beguines. Breiten originally referred to a large field; the name was later transferred to the house. In 1841, the Breiten farm consisted of two houses and was historically known as Borsikon. Names like these and their dates offer a different way to discover the landscape than routes and nature observations do.

The museum and tunnel of the Riedhof Mine are open on selected Saturdays to visitors, schools and groups. To get there, take the S9 train to Affoltern am Albis, then bus 225 or 235 towards Aeugstertal, and walk five minutes from the Aeugstertal-Kloster stop. Check the opening dates before visiting and the connections before travelling. This lets you plan your visit to the mine around the right transport, rather than assuming it is an activity available at any time.

When looking for a holiday apartment, your planned focus can help guide your choice: will you spend most of your time at the lake and enjoying summer activities, on a longer hike or at the mine? The options described here differ in both subject and time commitment.
