What Travellers Say
Reviews Summary
Visitors praise the Bregenzer Ach Estuary Reserve for its unique natural beauty and the opportunity to witness a pristine river delta. The newly built observation platforms are a hit, offering great views. However, access can be challenging due to fluctuating water levels, and some find the sandbanks are becoming overgrown.
"A little further inland, about 5 km, you can find this natural phenomenon on the Ache. Huge stone forming with extremely powerful currents."
Dennis Derksen
"A beautiful hiking trail always along the lake. I went during the week. There are probably more hikers on the weekend. It's easy to avoid it"
Heidi Fest
"The mouth of the Bregenzerach River is normally quite difficult to reach, and only possible during certain times of the year (if the term "seasons" is even still relevant). Furthermore, the water levels of the Bregenzerach River are crucial, as they vary between low, normal, high, and raging floods. Since you have to cross two-thirds of the river or tributaries to reach the island, this is only possible at low water levels. Apart from that, some truly fantastic observation platforms for visitors have been built to the left and right of the mouth in recent years! Approaching the island by boat and mooring is prohibited or punishable by law.
Here you will find a completely natural river delta with its diverse flora and fauna. A truly perfect beauty that only nature can create..."

Understanding the Estuary's Dynamics
Recent years have seen the development of observation platforms to the left and right of the mouth. These structures provide visitors with excellent, safe vantage points to appreciate the natural beauty of the delta without disturbing the delicate ecosystem. The reserve is celebrated for its diverse flora and fauna, making it a haven for nature enthusiasts and a prime example of a natural river delta.
It's important to note that the area is protected. Approaching the island by boat and mooring is strictly prohibited and carries legal penalties. Visitors are encouraged to admire the estuary from the designated platforms or from the lake itself, perhaps via a boat tour, to ensure the preservation of this unique natural habitat.
Experiencing the Reserve from the Lake
Specifically, the shallows that form on the Lake Constance side are a notable feature. These areas create natural sandbanks where visitors can easily stand, and the water tends to be warmer, making it a pleasant spot, especially for families with children. This gentle introduction to the estuary's edge provides a different, more accessible experience compared to the more rugged land-based access.
While direct mooring at the island is forbidden, enjoying the views from a boat on the lake is a fantastic alternative. Local boat tours operating on Lake Constance may offer excursions that provide excellent views of the estuary, allowing you to witness its grandeur without impacting the protected environment.
