Unterer Gaisalpsee: A Scenic Alpine Lake in Bavaria

Nestled in the Allgäu Alps of southern Bavaria, Unterer Gaisalpsee is a serene mountain lake that captivates hikers and nature lovers alike. Located near the village of Reichenbach (Oberstdorf area), this lake is a perfect destination for a day hike with dramatic scenery, waterfalls, alpine meadows, and tranquil water.

📍 Location & Access

• The hike commonly begins from Reichenbach, in the Allgäu region. 

• Trails are well-marked toward Gaisalp, passing through Reichenbachtobel (a gorge with small waterfalls) before ascending toward the lake. 

• Some routes require sure-footedness and are more challenging in sections. 

⛰️ Distance, Elevation & Duration

• Round-trip distance: ~ 8–9.5 km (depending on path) 

• Elevation gain: ~ 640–670 m 

• Estimated time: ~ 4 hrs total (about 2 hrs up + 1.5–2 hrs down) 

• The hike is often rated “medium to difficult” depending on fitness and trail conditions. 

🌿 Highlights & Landscape

• The route begins through a gorge (Reichenbachtobel) with cascading water and mossy cliffs. 

• After the gorge section, you pass through lush alpine meadows, with plenty of photo opportunities of wildflowers and panoramic views. 

• Upon nearing the lake, the trail becomes steeper and rockier, demanding more effort. 

• The lake itself is a peaceful alpine basin, nestled among rugged peaks — a perfect spot to rest, reflect, or even dip your feet (water is cold!). 

✅ Tips for the Hike

• Wear sturdy hiking shoes with good grip, especially for the steeper/rocky parts.

• Start early in the morning to avoid afternoon crowds and give yourself buffer time (weather in mountains can shift).

• Bring water, snacks, and possibly a rain shell — mountain weather can change quickly.

• Check parking availability in Reichenbach; during peak season it might fill up. 

• Respect nature — carry out trash, stay on marked trails.

• If you have extra energy, one can continue beyond the lake toward summits or ridgelines in the area
