Surrounded by southern Black Forest mountains and grassy fields is the village of Todtnau with a population of 5000 people.
Todtnau is popular with day trippers on motor bikes or hikers during the summer. In winter there it is an excellent base for skiers with an abundance of accommodation and good access to the main ski slopes in the Black Forest.
The biggest attraction in Todtnau, especially for families, is Germany’s longest toboggan run called the Hasenhorn roller coaster (Rodelbahn). Open all year round, the panorama is magnificent on the chairlift ride up the mountain and as you fall downhill on the three kilometre coaster track, you can control your own speed to take in the view of Todtnau below.
The ride is free for one ride per day if you have the local tourist card KONUS which is given to you at your accomodation and includes free public transport.
This website link has a video of the ride and more information.
Mountain bikes can be hired and the idea is to take the bike up the same chairlift for a challenging bike track run back down.
Nearby is the Todtnauer waterfall which is the highest in Germany with a drop of 97 meters. Not spectacular but worth seeing on a hot day or hike around the forest nearby. There is also rope climbing available here. The track to the falls is easy to walk and there is a bridge crossing midway.
