Seealpsee
Appenzell Innerrhoden
Seealpsee is a picturesque mountain lake located at an elevation of 1,143.2 meters in the Alpstein range of the canton of Appenzell Innerrhoden, Switzerland. Covering an area of approximately 13.6 hectares, it is renowned for its crystal-clear waters and idyllic natural setting. The lake is accessible by foot from Wasserauen via a mostly asphalted trail or from Ebenalp through a steeper, forested path passing notable landmarks such as the Wildkirchli caves and the famous Berggasthaus Aescher. The western end of the lake is dominated by the Berggasthaus Forelle, a mountain inn with a large open-air terrace offering spectacular views. Seealpsee is not only a popular destination for hikers and nature lovers but also serves practical functions, providing hydroelectric power and drinking water to the nearby town of Appenzell. In recent years, the lake has experienced unique natural phenomena, including a rare red coloration caused by the dinoflagellate alga Tovellia sanguinea, which thrives in nutrient-poor cold alpine waters. Visitors can enjoy swimming in the refreshing waters during warm summer days, making it a perfect spot for relaxation after mountain excursions. The surrounding network of hiking paths connects Seealpsee to other remarkable sites within the Appenzell Alps, including the Säntis mountain, enhancing its appeal as a gateway to alpine exploration.
