The Gigerwald Dam is an impressive arch dam located in the picturesque Calfeisental valley, within the municipality of Pfäfers in the Canton of St. Gallen, Switzerland. Standing at a height of 147 meters, this significant man-made monument holds back the waters of the Tamina River, forming the expansive Gigerwaldsee reservoir. Situated at an elevation of approximately 1343 meters above sea level, the Gigerwaldsee is notable as the largest lake located exclusively within the canton of St. Gallen, nestled amidst the rugged peaks of the Glarus Alps.
Visitors consistently praise the spectacular views offered from the dam wall, which stretches 430 meters across the valley. The surrounding landscape, characterized by steep rock faces rising nearly 2,000 meters, creates a dramatic backdrop for the tranquil Gigerwaldsee. Many find the engineering marvel of the dam itself, combined with the wild beauty of the mountain valley, to be a truly captivating experience. The opportunity to walk or even cycle across the dam wall is a highlight for many, providing unique perspectives of both the reservoir and the valley below.
Before heading out, it's helpful to know that the area around the Gigerwald Dam is popular for outdoor activities, so comfortable footwear is recommended for exploring. While the dam wall is accessible, some trails in the Calfeisental can be challenging. Parking is available, and information boards on the dam provide technical data about its construction and the reservoir. Due to recent renovation work, the reservoir was drained and is expected to refill in spring 2025, with a reopening scheduled for early summer 2025, so checking current conditions is advisable.
The best time to visit the Gigerwald Dam is typically during the warmer months, from late spring to early autumn, when the mountain roads are clear and the weather is most favorable for hiking and cycling. The area offers a variety of activities, from leisurely strolls along the reservoir to more strenuous hikes into the surrounding mountains. Cyclists particularly enjoy the relatively easy asphalt ascent to the dam from Vättis, which offers wonderful views along the way. Guided tours of the dam and power station are also available for those interested in its operational history.
A popular way to experience the area is by following the road along the southern shore of the Gigerwaldsee, which includes several tunnels and leads to the historic Walser settlement of St. Martin at the far western end of the lake. This route provides continuous scenic vistas of the reservoir and the impressive rock formations. Hikers can explore various Gigerwald Dam trails and routes that branch off into the Calfeisental, offering diverse terrain and difficulty levels.
Many visitors are struck by the sheer scale of the Gigerwald Dam and the serene beauty of the Gigerwaldsee. The experience of driving or cycling over the 147-meter-high dam wall, with the vast reservoir on one side and the deep valley on the other, is often described as unforgettable. The tranquil atmosphere, especially further along the reservoir towards St. Martin, provides a perfect escape into nature, allowing for moments of quiet reflection amidst the grandeur of the Swiss Alps.
Whether you're interested in the engineering marvel of the Gigerwald Dam, the natural beauty of the Calfeisental, or exploring the Gigerwald Dam natural features and landmarks, there are numerous routes to discover.
