블라우에 라케

Blaue Lacke is situated at an elevation of approximately 2,289 to 2,294 meters above sea level. The terrain around the lake is typical alpine, characterized by granite boulders and high-altitude vegetation. While the hike, especially from the Sulzenauhütte, is considered relatively short and pleasant, sturdy footwear is highly recommended due to the uneven, rocky paths.

Beyond the stunning lake itself, you'll find numerous Steinmännchen (stone cairns) scattered around the area, adding a unique, almost mystical ambiance. These cairns are often built by hikers and are a notable feature. For panoramic views, the immediate surroundings of the lake offer excellent photographic opportunities of the turquoise water against the rugged alpine backdrop.

Access to Blaue Lacke typically involves reaching the Stubaital valley first. For parking, you would usually drive to a trailhead further down the valley, such as the one leading to the Sulzenauhütte, and then hike up. Specific parking areas like the one at the Grawa Alm or the Sulzenaualm are common starting points. Public transport options include buses that run through the Stubaital, connecting various villages and trailheads, making it possible to reach starting points without a car.

While the intro highlights warmer months for hiking, visiting Blaue Lacke in winter presents a different challenge. The area becomes snow-covered, and trails can be difficult or dangerous due to snow and ice. Access might be restricted, and specialized winter hiking equipment (snowshoes, crampons) and experience are essential. It's generally recommended for experienced winter hikers only, and conditions should be checked thoroughly before attempting a winter visit.

The hike to Blaue Lacke, particularly the section from the Sulzenauhütte, is often considered manageable for families with older children who are accustomed to alpine hiking. For younger children, the elevation gain and rocky terrain might be challenging. Dogs are generally welcome on trails in the Stubai Alps, but they should be kept on a leash, especially in areas with grazing livestock or wildlife. Always ensure your dog is fit enough for the alpine environment and carry enough water for them.

Blaue Lacke itself is a high-alpine lake without direct amenities. However, the nearby Sulzenauhütte mountain refuge, located about 500 meters southwest, offers food, drinks, and overnight accommodation during the hiking season. Further down in the Stubaital valley, you'll find a wide range of cafes, restaurants, and hotels in villages like Neustift im Stubaital or Fulpmes.

The hiking time to Blaue Lacke depends on your starting point. From the Sulzenauhütte, it's a relatively short detour, often taking around 15-30 minutes one way. If you're starting from the valley, for example, from the Grawa Alm parking area, the hike to the Sulzenauhütte and then to Blaue Lacke can be a half-day or full-day excursion, typically ranging from 2.5 to 4 hours one way, depending on your pace and fitness level.

While the water of Blaue Lacke is famously icy-cold due to its glacial origin and high-alpine location, some brave visitors do enjoy a quick, refreshing dip. It's not a designated swimming spot, and there are no facilities. Be prepared for extremely cold temperatures, even on warm summer days, and exercise caution if you decide to enter the water.

Blaue Lacke is a highlight along the popular Wilde Wasser Weg (Wild Water Trail). If you're looking for less crowded options, consider exploring other sections of the Wilde Wasser Weg that might be less frequented, or venture onto trails that lead to higher, more remote peaks or other smaller tarns in the Stubai Alps. Consulting a detailed hiking map of the region can reveal numerous alternative routes.

Blaue Lacke is a relatively recent geological formation, a product of climate change and glacial retreat following the last ice age. It was formed by the melting of the Sulzenau Glacier (Sulzenauferner) and is dammed by the glacier's moraine from around 1850. The lake's vibrant blue color is often attributed to glacial flour—fine rock particles suspended in the water—reflecting the blue spectrum of light.

Yes, Blaue Lacke can be incorporated into several circular hiking routes. A common approach is to start from the valley, hike up to the Sulzenauhütte, visit Blaue Lacke, and then continue on a different path back down to the valley, perhaps via another hut or a different section of the Wilde Wasser Weg. Many hikers combine it with a loop that explores the upper Sulzenau valley before descending. You can find various route suggestions on hiking platforms.

The striking turquoise color of Blaue Lacke's water is primarily due to glacial flour. This refers to extremely fine rock particles, ground down by glacial erosion, that remain suspended in the water. When sunlight hits these particles, they scatter the blue and green wavelengths of light, giving the lake its characteristic vibrant hue. The intensity of the color can vary depending on the light conditions, cloud cover, and the amount of glacial meltwater flowing into the lake.
