Tännforsen
Jämtlands län
Tännforsen is the largest waterfall in Sweden, located in Åre municipality within the province of Jämtland. The waterfall features a total height of 37 meters, including a vertical drop of 26 meters and a width of 60 meters, creating a dramatic water surface area of approximately 1,560 square meters. It is part of the Indalsälven river, connecting the lakes Tännsjön above and Öster-Noren below. The water flow varies seasonally, peaking in late May with 200 to 400 cubic meters per second, and sometimes exceeding 800 cubic meters during exceptional spring floods, such as in 1995. In winter, the waterfall is often covered with ice, creating a striking natural spectacle. Tännforsen is one of Jämtland's most visited natural attractions and remains largely undeveloped, preserving its raw beauty.

Today, the area is protected as a nature reserve and part of the Natura 2000 network, ensuring conservation of its unique environment. Visitors can explore a marked 1-kilometer trail called "Blomsterslingan" that circles the waterfall, offering views from both the top and bottom. Guided tours are available during the summer season, enhancing the visitor experience with expert insights. Facilities near the site include parking, restrooms (open when possible), and WiFi, supported by a modest service fee.
