Grünsee is quite remote and not directly accessible by public transport. The most common approach is to take a train to Zermatt. From Zermatt, you can use the Sunnegga funicular to reach Sunnegga, which serves as a popular starting point for hikes towards Grünsee, often as part of the Five Lakes Walk. From Sunnegga, the lake is then accessible by foot or off-road bike.
Zermatt is a car-free village, so you cannot drive directly to the trailhead. Visitors typically park their cars in Täsch, the last village accessible by car before Zermatt. From Täsch, you can take a shuttle train or taxi to Zermatt. Once in Zermatt, you'll proceed to Sunnegga via funicular to begin your hike to Grünsee.
The hike to Grünsee is generally considered gentle and family-friendly. While it involves alpine terrain, many routes, especially those from Sunnegga, are well-maintained and suitable for a range of fitness levels. It's often incorporated into the Five Lakes Walk, which offers varying lengths and difficulties, but the section to Grünsee itself is not overly strenuous.
While the intro suggests late spring to early autumn as the best time, winter hiking to Grünsee is possible but requires specific preparation and caution. Trails will likely be covered in snow and ice, necessitating appropriate winter hiking gear like snowshoes or microspikes, and checking avalanche conditions is crucial. Some routes might be closed or significantly more challenging during winter months.
Yes, you can swim in Grünsee! Many visitors enjoy a refreshing dip. However, as the lake is fed by the Findel Glacier, the water is strikingly cold, even in summer. It's a glacial lake, so expect invigorating temperatures rather than warm swimming conditions. Don't forget your swimming trunks if you're brave enough!
Generally, dogs are welcome on hiking trails in the Zermatt region, including those leading to Grünsee. However, it's always recommended to keep them on a leash, especially in areas with livestock or wildlife, and to clean up after them. Be mindful of other hikers and cyclists.
Grünsee is a small lake, so walking around its immediate shores doesn't take long – perhaps 15-30 minutes for a leisurely stroll. Most visitors spend more time relaxing by the lake, enjoying a picnic, or taking photos. The longer time commitment comes from the hike to Grünsee, often as part of a larger route like the Five Lakes Walk.
There is a Grünsee Mountain Lodge nearby, which serves as a resting point for hikers and offers refreshments. For more extensive options, you would need to head back towards Sunnegga or Zermatt, where you'll find a wide range of restaurants, cafes, and accommodation choices.
Grünsee offers stunning panoramic views of the Matterhorn, Weisshorn, and Obergabelhorn. The best spots for Matterhorn photos are typically along the lake's eastern shore, where the iconic peak is often reflected in the emerald-green waters. Early morning or late afternoon light can enhance the photographic experience.
Grünsee is a popular destination, especially during the peak summer months (late spring to early autumn) and on weekends. The intro notes that an early start can help ensure a more tranquil experience. While it can get busy, the serene atmosphere and vast landscape still allow for moments of peace, particularly if you venture slightly off the main paths.
The landscape surrounding Grünsee is a former glacial area, rich in diverse alpine flora and interesting rock formations. You'll find a variety of high-altitude plants adapted to the harsh environment. The geology itself, shaped by ancient glaciers, tells a story of powerful natural forces, making it a fascinating area for nature enthusiasts.
