Mummelsee: The Black Forest’s Enchanted Lake and the Trails That Lead to It
A glacial lake with folklore, approachable hikes and a steady, old‑growth hush—how to make the most of a morning or half‑day at Mummelsee.
If you arrive at Lake Mummelsee in the low, blue light of morning it feels like stepping into a story someone still remembers how to tell. A pale ring of mist lifts off the water and the black spruces that give the Black Forest its name lean in like listeners. A wooden pier reaches into a glassy bowl of lake; the surface catches the first pale sun and holds it. People come for a half-hour and stay a half-day. They come to walk a small, honest loop and to let the forest do something deliberate to their speed and agenda.
Trail Wisdom
Time it for morning or late afternoon
Visit early or late to avoid coach crowds and catch the best light for photography.
Wear grippy shoes
The short lakeside trail is easy but can be slippery where roots and stones appear—trail shoes or light hikers are ideal.
Layer up
Elevation brings cool air even in summer—pack a wind/rain shell and a midlayer.
Respect the shoreline
Stick to paths and don’t swim in protected areas; the ecosystem is fragile and part of regional conservation efforts.
