Explore Alter Rhein
Diving in the Alter Rhein offers a unique and captivating experience in the Alpine Rhine valley, nestled between St Gallen and Vorarlberg. This site is the remnant of the old riverbed of the Alpine Rhine, now transformed into a picturesque nature reserve. With depths reaching up to 9 meters/30 feet, it is an ideal spot for beginners to hone their skills. The Alter Rhein serves as a tranquil practice ground, where divers can explore the serene waters and encounter a variety of fish, predominantly pike.
One of the charms of diving in the Alter Rhein is the seasonal variation in water clarity. During the winter months, divers can enjoy clearer visibility, making it easier to observe the aquatic life and underwater features. In contrast, the summer months bring cloudier waters, adding a different dimension to the diving experience. Moreover, the site is well-suited for night dives, offering a chance to discover the nocturnal habits of the local marine life and enjoy the peacefulness of underwater exploration under the stars.
