Biosphärenreservat Karstlandschaft Südharz

Come to the Südharz for a lake that can disappear underground, story-led walks and a close look at a changing gypsum landscape.

About

Come to the Südharz for a lake that can disappear underground, story-led walks and a close look at a changing gypsum landscape. A good first stop is the Bauerngraben walking car park on the L234 between Roßla and Questenberg. From here, three self-guided story walks offer a choice between a small orchard outing, a circuit around an extraordinary lake basin and a longer adventure towards Questenberg.

The lake is the surprise. The Glasebach flows into the Bauerngraben and drains through openings in the ground. When those outlets cannot take the water, a lake forms beneath the rock wall; at other times, you look across a dry basin. Either version tells the same story of soluble rock and underground drainage. There is no dependable season for finding it full, so let the question “water or no water?” be part of the visit.

This reserve lies in Sachsen-Anhalt, between the Stolberg and Sangerhausen areas. It protects part of a much larger karst landscape that continues through Thüringen and Niedersachsen. White gypsum exposures, shaded beech woods, old fruit trees and villages sit close together. The contrasts make a satisfying family day: a flower beside the path, a woodland sound, then a view across land whose shape is still changing.

People have left their own marks. Copper-shale mining produced small spoil heaps, while grazing and mowing helped keep orchards and open grassland from becoming woodland. These are places to notice slowly. Pick one main walk and one additional stop rather than trying to collect every attraction across the reserve in a single day. Explore the grounds like a pro—download the Snappit app to instantly identify animals and plants.

The gypsum and related rocks began as deposits of the Zechstein sea around 250 million years ago. Much later, water dissolved them into the hollows, springs and caves seen today. Centuries of copper-shale mining and small-scale agriculture added another layer to the landscape. Sachsen-Anhalt designated the biosphere reserve in 2009; UNESCO recognition is still being sought. At Heimkehle, the memorial recalls concentration-camp prisoners and other forced labourers made to work in an underground armaments factory in 1944–1945, an important part of the cave’s history to discuss sensitively with children.

What to do here

For a short outing, choose the Streuobstwiesentour, the reserve’s 900 m orchard circuit from the Bauerngraben car park. The free Locandy story introduces Karsten the badger and Freddy the young wild boar, with a fairy-tale twist among the fruit trees. These are story characters, so children need not expect to meet the real animals.

The 3.5 km Bauerngrabenrundweg is the best introduction to the geology. It returns to the same car park and explores the basin and its surroundings. The route includes the high rim above the basin: keep children close, stay well back from edges and follow the current marked line. This is a walk requiring care around steep drops, even though its distance is modest.

For children who enjoy a longer story, Abenteuer am Questenberg is a 4.5 km circuit from the same start, through orchards and woods towards the Questenberg viewpoint. The tale turns the walk into a rescue mission and introduces the Questenfest tradition. Expect an uphill woodland outing rather than a level promenade. All three distances include the return to the designated start; village, bus-stop and accommodation approaches are extra.

On a separate stop at Uftrungen, Heimkehle offers guided cave visits, a free visitor-centre exhibition and outdoor nature play. Cave entry is paid, guided only and restricted to children aged three or over. Take a warm layer even in summer. The guided passage crosses the Sachsen-Anhalt–Thüringen boundary, although the biosphere reserve itself lies in Sachsen-Anhalt. Alternatively, combine Stolberg’s half-timbered streets with the “Buchen musst Du suchen” beech-forest exhibition at the castle, checking opening and access arrangements first.

Seasonal info

Check the reserve and attraction notices before travelling, and obey barriers on the day. Wet leaves, frost and poor visibility are reasons to avoid the steep rim sections. Roadworks affect VGS buses 450, 451 and 453 in Roßla from 1 September until provisionally 18 December 2026; Roßla, Post is not served. At Schloss Stolberg, ongoing works can prevent vehicles reaching the forecourt. Confirm arrangements if you need close drop-off access.

Accessibility

The orchard circuit is the shortest option, but its length does not establish wheelchair or pushchair suitability. Ask the reserve about its current surface and gradients. Bauerngraben’s cliff-edge sections and the climb towards Questenberg need more careful route choices; no continuous step-free route is promised here. Heimkehle’s guided visitor path is designed for wheelchair access. Contact the cave before booking to check the approach and arrangements for your particular chair or walking aid.

Walks and routes

Streuobstwiesentour: Vielfalt Streuobstwiese

A compact orchard story with talking fairy-tale trees. Give each child a chance to notice one difference between the trees before the next audio stop.

Choose for its short distance. Confirm suitability separately for a wheelchair, pushchair or limited walking range.

Streuobstwiesentour: Vielfalt Streuobstwiese

Bauerngrabenrundweg: Karst kapieren mit Karsten

Follow the geology story around the episodic lake basin and compare the ground under the trees with the open hollow below.

Children need close supervision near the rim. Avoid this option if exposed edges or uncertain footing are unsuitable for your group.

Bauerngrabenrundweg: Karst kapieren mit Karsten

Abenteuer am Questenberg

Follow the fictional rescue story through the orchard-and-woodland landscape to the Questenberg views. Leave time for the puzzles rather than treating it as a fast fitness loop.

A longer hill walk; the family-friendly label does not establish suitability for wheels. Ask for current route advice if steps or steeper sections are a barrier.

Abenteuer am Questenberg

A small first visit

Choose the orchard story and leave the rest optional. Take a snack break after finishing the loop, then decide together whether another stop sounds enjoyable. This works better than committing tired children to a second circuit.

Geology above and below ground

On a dry day, make Bauerngraben the main walk, with a separately booked Heimkehle tour as the second anchor if everyone meets the cave’s entry rules. Leave travel and a meal break between them; the cave is at Uftrungen, not beside the walking car park.

Woods, stories and a town

Give the Questenberg circuit most of the morning or afternoon. On a different part of the day, explore Stolberg at your own pace. Any village stroll or castle approach is additional walking and is not included in the 4.5 km circuit.

Things to try

Solve a water puzzle

At a safe viewpoint, ask everyone where the Glasebach’s water might go. Draw the basin with a hidden drain underneath, then compare your ideas with the story or information board. Keep this a looking game from the path.

Give an orchard tree a portrait

Choose a tree visible from the walking route and sketch its outline. Does it have blossom, fruit or bare branches? The same subject gives children a reason to return in another season without needing to collect anything.

Compare two woodland worlds

On the way between open ground and woodland, notice how light, wind and ground plants change. Each person can describe one difference. There is no need to name every species for the comparison to work.

A weekday explanation of the landscape

Roßla’s indoor exhibition is the simple alternative to walking wet cliff-edge paths. Its published visiting hours are Monday to Thursday, 08:00–15:30, and Friday, 08:00–12:00; check holiday exceptions and current notices before setting out.

A guided underground visit

Heimkehle can work on a wet day when tours are running and the group meets the entry conditions. The cave stays around 8 °C, so bring a jacket and suitable shoes. Its memorial also makes this a thoughtful history visit, rather than an uninterrupted play activity.

Beech woods indoors at Stolberg

The castle’s Natura 2000 exhibition gives the surrounding beech forests a human and natural-history context. Confirm the exhibition’s opening separately from other castle activities and check the building-work access notice before travelling.

Wildlife and habitats

A dependable subject for noticing the woodland itself: compare the canopy, fallen leaves and smooth trunks visible from the path. Try photographing one tree and the light beneath it in different seasons.

In spring, look from woodland paths for broad-leaved patches and later white flower clusters. Leave the leaves and flowers untouched; look closely without picking or tasting them.

The small purple-blue spring flowers are worth slowing down for. Look from woodland paths rather than stepping across the forest floor for a closer picture; a flower too far away can simply be left unphotographed.

Watch for yellow flowers in spring on open grassland visible beside public paths. Compare the open, sunny setting with the shady flower patches in the woods, without crossing the meadow to reach an individual plant.

A possible woodland discovery rather than a reliable sighting. The male’s enlarged jaws resemble antlers. If one appears, photograph it where it is and give it room. Leave logs and stumps untouched; searching inside decaying wood damages its habitat.

Watch your footing if an amphibian appears on a damp woodland path. The yellow-and-black animal is a fortunate encounter, not a reason to search under stones or logs. Observe without handling and let it continue on its way.

Pause at sunny path margins beside dry grassland and watch for a small movement before walking on. Stay still if a lizard appears; chasing it into the vegetation is likely to end the encounter and disturb its shelter.

Add a listening pause to a woodland walk around Stolberg, then scan the trunks from the path if a bird appears. A clear photograph can help with identification, but do not follow a bird to a tree cavity.

Treat the wildcat as a reason to protect connected, quiet woodland rather than an animal to tick off on a day trip. Sightings are unusual, and a distant tabby-like cat is not enough for a confident identification. Never approach kittens or investigate possible dens.

Stories and discoveries

Water can change the route itself

The trail managers describe earlier sections around Bauerngraben lost to collapsing or dissolving ground. That is why a downloaded route is never a reason to step past a present-day barrier.

Mining left unusual plant habitats

Some old copper-shale spoil heaps support specialist vegetation able to cope with metal-rich ground. View them from established routes and leave the material alone. The heaps are part of both the region’s industrial history and its present ecology.

A castle linked to the House of Orange

Juliana of Stolberg was born at the castle in 1506 and became the mother of William of Orange. The building later served as a holiday home in the GDR; restoration continues today.

When to visit

Let the conditions choose the day

For spring plants, leave time for many short pauses. On hot days, avoid trying to finish every open stretch at midday. In autumn and winter, shorten the plan if slippery ground or early darkness would make the return uncomfortable. The lake level should be treated as a surprise in any season.

Getting there and practical advice

Use a named visitor base

Roßla’s reserve exhibition explains the landscape at Hallesche Straße 68a. For a different indoor base, Heimkehle’s visitor centre is at An der Heimkehle 3, Uftrungen. These are separate stops with their own opening arrangements. Carry supplies for the walks rather than relying on refreshment or toilet facilities at the trailhead.

Rural connections need planning

Use Roßla or Berga-Kelbra as rail gateways and check onward travel for the exact date. The Roßla ServiceBus connects nearby villages on Tuesdays and Thursdays; some stops require booking at least one hour ahead. A bus to a village is not necessarily a bus to the Bauerngraben car park. Check the pedestrian approach separately and use the operator’s current diversion timetable.

Ask about the whole outing

For the story walks, ask about the surface, inclines and return route, not just the headline distance. At Heimkehle, confirm transfer and mobility arrangements before buying a tour. If visiting the Stolberg exhibition, ask where vehicles can currently stop: works may block the forecourt, so a nominally accessible destination may still involve a difficult approach.

Good to know before you go

Choose the correct start

For the three story walks, navigate to Wanderparkplatz Bauerngraben – Episodischer See on the L234. The reserve office in Roßla is a separate destination.

Prepare the stories

Install Locandy and load your chosen tour before leaving a reliable connection. Charge the phone and carry the official leaflet as a backup; stop safely when using the screen.

Plan your return bus first

Roßla and Berga-Kelbra are rail gateways. Rural onward services vary by day; some ServiceBus stops need advance booking. Check the exact stop and both journeys in VGS or INSA.

Pack for the route

Bring grippy walking shoes, water and a snack. Keep hands free near the Bauerngraben rim, and save the photographs for a secure stopping place.

Use the weekday base

The reserve exhibition is at Hallesche Straße 68a, Roßla. Its advertised visitor hours are on weekdays; check before making it your rain plan.

Leave habitats intact

Keep to marked paths, keep dogs under close control and preferably on a lead, and leave flowers, timber and stones where they are. Never enter an unprepared cave or mine opening.

Give the cave its own plan

Children under three and dogs cannot enter Heimkehle. Check the current tour calendar and tickets, and leave cameras off during the Fledermausgeflüster light-and-sound sequence.

Frequently asked questions

No. Full and dry periods can both last a long time, and the changes do not follow a dependable annual timetable. The basin, cliff and disappearing stream explain the landscape even when there is no open water.
It is a biosphere reserve designated by Sachsen-Anhalt. UNESCO recognition is being sought. The reserve’s boundary is also different from the wider southern Harz karst landscape and its long-distance walking trail.
Start with the 900 m orchard circuit if short distance matters most. Children who are steady on their feet and happy to stay beside an adult may enjoy the longer story walks. If steep edges are a concern, choose an exhibition instead of the Bauerngraben rim.
The Locandy story tours are free. Download the app and your chosen story beforehand. Heimkehle cave tours are a separate paid activity with their own entry rules and schedule.
Wildcats are very elusive, and a woodland walk is unlikely to reveal one. Bats may sometimes be noticed on a guided cave visit, but sightings are incidental. Never look for roosts or disturb resting animals; plants and landscape details make much more dependable photo subjects.
