Hinterer Gosausee in Gosau

Hinterer Gosausee forms the natural conclusion of the Gosau valley. Official tourism describes it as lying at the foot of “King Dachstein,” where the valley narrows beneath the massif. The upper lake’s location explains why it feels more enclosed than Vorderer Gosausee. The surrounding mountains occupy more of the horizon and the visitor has already walked well beyond the roadhead.

At around 1,150 metres elevation, the lake is significantly higher than Vorderer Gosausee at roughly 937 metres. The climb is gradual rather than dramatic, but the elevation gain becomes evident through vegetation, temperature and the increasing presence of Alpine terrain. Even on a warm day at the lower lake, the upper basin can feel cooler.

The lake is part of the Dachstein Mountains and the wider Hallstatt-Dachstein/Salzkammergut cultural landscape. Its scenery is therefore not isolated from the region’s World Heritage context. The same geological and mountain systems that shaped settlement, pasture, salt routes and tourism around Gosau also define the lake’s physical setting.

The upper valley has no dense built shoreline. That is one of its strengths. A seasonal hut provides hospitality, but the water remains framed primarily by natural slopes and mountain architecture. Visitors should preserve that character by carrying out litter and staying on established routes.

The lake’s enclosure also affects sound and atmosphere. The farther end of the valley is quieter than the road-accessible first lake, and cliffs and forest reduce the sense of a broad tourist basin. Weather can move across the walls quickly, changing light and visibility in minutes. This more enclosed setting is one reason the upper lake feels substantially more Alpine even though it is reached by a relatively accessible summer trail.

That sense of remoteness should be kept in perspective: the route is popular and well known, but there is still a meaningful reduction in infrastructure between the lower and upper lakes. Visitors gain a more natural setting without needing a technical mountaineering ascent. This balance is one reason Hinterer Gosausee is especially suitable for experienced walkers who want more than a roadside panorama but do not need a summit objective.

The standard visitor route begins at the road-accessible Vorderer Gosausee. From the lower lake, official trail descriptions follow a broad route along the valley, then pass the Niedere Holzmeisteralm and Gosaulacke before climbing toward the upper basin. The overall walking time is commonly given at around one and a half hours in one direction.

The route is not technically difficult in ordinary summer conditions, but it is still a mountain walk. Uneven gravel, wet roots, short steeper sections and changing weather distinguish it from an urban lakeside promenade. Families with hiking experience can complete it, but a pushchair-friendly lower-lake path should not be assumed to continue all the way to Hinterer Gosausee.

A current 2026 rockfall warning affects the first part of the route. The left side of Vorderer Gosausee is closed through 30 September, and hikers bound for the upper lake must use the right side. The restriction was issued after heavy rain and falling rock. This is exactly the kind of temporary Alpine hazard that can override a general “open” status.

Start early enough to return in daylight. The one-and-a-half-hour estimate is only walking time and does not include photography, lunch, weather delays or time at Gosaulacke. A realistic round trip for leisure visitors is several hours. Carry water even if you plan to stop at the seasonal hut, because operating days can change.

The walk is especially rewarding because the return uses the same landscape in reverse. Views that were behind you on the ascent open toward the lower valley, and Gosaulacke may appear different as light changes. Hikers who treat the return as merely necessary travel miss half of the visual experience. Allow enough time so the descent does not become a race against darkness.

Hinterer Gosausee is hydrologically connected with the lower valley in ways that are not obvious from the surface. Under normal conditions, much of its water drains underground through the Dachstein limestone system. During high-water conditions, overflow can travel toward the Gosaulacke basin. That mechanism helps explain why the middle lake can appear full after snowmelt or heavy rain and much smaller in dry periods.

This underground behavior is characteristic of karst landscapes, where soluble limestone allows water to move through cracks, caves and subsurface channels. The Dachstein is famous for its karst geology, and the Gosau lakes offer an accessible way to see some of the consequences even without entering a cave. Surface water, underground drainage and intermittent basins all coexist in a short valley.

For visitors, this means water level is part of the landscape rather than a fixed backdrop. Wetter years and seasons can change shorelines and overflow conditions. The upper lake may still look stable while Gosaulacke below changes dramatically. Observing both on the same day provides a useful lesson in how connected mountain basins behave.

The hydrological link also argues against treating each lake as an unrelated photo stop. Vorderer Gosausee is managed as a reservoir, Gosaulacke is intermittent and Hinterer Gosausee is the more natural upper basin. The three together show different relationships between water, geology and human use.

Karst drainage also helps explain why visible surface streams can be deceptive in the Dachstein. Water may disappear underground and re-emerge far from where a visitor expects. The Gosau lakes sit within that limestone environment, so their apparent isolation from one another is only partial. The valley is connected by subsurface routes that are invisible from the trail.

Hohe Holzmeisteralm lies near Hinterer Gosausee and provides the principal seasonal hospitality in the upper valley. Current tourism information lists the hut as open from the beginning of June to the end of September, with Wednesday as the regular closing day. It operates on a self-service basis and offers regional food and pastries.

The hut matters because it gives hikers a practical break without transforming the lake into a resort. There is no large hotel, car park or row of restaurants at Hinterer Gosausee. The Alpine pasture setting remains dominant, and the hut’s seasonal rhythm matches the ordinary hiking season.

Do not rely on the hut as the only source of food or water. Weather, staffing or end-of-season conditions can change operations, and Wednesday is the published rest day. Carry basic supplies and treat the hut as an optional enhancement rather than an essential safety resource.

The pasture environment also requires respectful behavior. Livestock may be present, dogs should be controlled and hikers should stay clear of agricultural operations. Mountain huts are workplaces as well as visitor services. Follow local signs and do not enter private farm buildings.

The hut’s presence also marks a traditional Alpine land-use layer. Pastures around the upper valley are not wilderness untouched by people; they belong to a long history of seasonal grazing and mountain agriculture. A meal at Holzmeisteralm therefore adds cultural context to the natural landscape, especially when visitors recognize that Alpine scenery has often been shaped by generations of managed pasture.

The ordinary visitor season is summer and early autumn, when the trail is free of persistent snow and the seasonal hut is operating. Long daylight hours make the round trip comfortable, while changing weather remains the main planning risk. Thunderstorms can develop quickly in Alpine terrain, so forecast checking is essential even on apparently easy lake walks.

Autumn brings colder mornings, shorter days and the gradual closure of seasonal services. The landscape can be especially attractive as vegetation changes, but the margin for delays becomes smaller. By late September, hikers should already carry warmer layers and should not assume summer hut operations continue beyond published dates.

Winter should be treated as a separate mountain undertaking. Snow and ice change route difficulty, and there is no regular winter maintenance or guaranteed safe pedestrian access to the upper lake. A natural site being “open” does not mean the summer trail remains easy or appropriate in snow.

Spring can also involve snowmelt, wet trails and high water. Gosaulacke may be fuller, but the path can remain muddy or snow-covered. Visitors should choose the season according to hiking experience rather than simply looking for the most dramatic water level.

Autumn also changes the crowd pattern. The upper lake can feel quieter after the peak summer season, but shorter days and colder weather reduce the margin for leisurely delays. September visitors should check sunset and carry a warm layer even if they begin in sunshine at the lower lake. The higher basin can cool quickly once the sun leaves the valley walls.

Reach the trailhead via the Vorderer Gosausee area. Regional buses 541/542 run toward Gosausee from connections at Steeg-Gosau station, and paid parking is available near the roadhead. Current tourism lists more than five hundred parking spaces across the lower visitor area, but popular days can still be busy.

There is no vehicle access for ordinary visitors to Hinterer Gosausee. Everything beyond the lower lake is on foot. This is important when planning with children, older travellers or anyone unused to hiking. Distance on a map can look short, but the return journey must always be included.

The upper lake is not barrier-free. There are no dedicated accessible facilities, and the trail surface and gradient rule out many mobility aids. Visitors who cannot make the hike can still experience the famous lower lake and Dachstein view from the accessible roadhead area.

No admission ticket is required for the lake itself. Parking, transport and food are the main costs. Bring weather protection, water, a charged phone and appropriate footwear. In poor visibility or severe weather, turning back is the correct decision; the upper lake will still be there another day.

Hinterer Gosausee is most rewarding when treated as a destination rather than an extension of a quick lower-lake photo stop. Allow time to sit by the water, look back down the valley and understand how far the landscape has changed since the roadhead. That slower pace is what distinguishes the upper lake from the much busier first Gosausee.

If you are already tired by the time you reach Gosaulacke, turning back is a sensible choice. Hinterer Gosausee is rewarding because the approach feels like a mountain outing; it should not become an obligation after energy or weather deteriorates. The best visit is one that leaves enough reserve for a safe return.

Photography is usually strongest when hikers give themselves enough time to wait for changing light rather than arriving at the lake with a fixed turnaround deadline. Clouds often move quickly across the Dachstein walls, alternately hiding and revealing the upper slopes. A short pause can transform the view, while rushing can make the destination feel less rewarding than the effort required to reach it.

Patience improves it.
