Harz Nature Park (Lower Saxony)

Come to Harz Nature Park for walks that connect woodland, wildlife and the ingenious ways people once used mountain water.

About

Come to Harz Nature Park for walks that connect woodland, wildlife and the ingenious ways people once used mountain water. A good family starting point is the Naturerlebnispfad at Clausthal-Zellerfeld: children follow a story about a young mine worker while trying activities with wood and animal tracks. For a quieter outing, choose Buntenbock’s meadows and ponds, where watching a diving bird can become the best part of the walk.

This guide covers the roughly 909-square-kilometre nature park in Lower Saxony, across the districts of Goslar and Göttingen. It excludes the Lower Saxony part of Harz National Park. Harz/Sachsen-Anhalt, Harz/Sachsen-Anhalt (Mansfelder Land) and Thüringen’s Südharz are separate nature parks too. Here, towns, farming and forestry are part of the experience. Choose one local outing rather than trying to cross the whole park in a day.

Around Clausthal-Zellerfeld and Buntenbock, the ponds were built for mining, and the meadows supplied fodder for livestock. Their value has changed: fluctuating pond margins support unusual plants, while lightly managed meadows provide flowers for insects. Farther south, the Rhumequelle reveals another kind of water story, as water that vanished into underground rock passages emerges as a river. Eager to name that creature? Identify any animal you find during your visit using the Snappit app.

The Lower Saxony nature park began in 1960, helped into being by local official and Harzklub chairman Hermann Kerl. Its boundary was enlarged in 2011. The surrounding landscape carries a much older mining history: trees supplied timber and charcoal, while ponds and channels stored and delivered water to power mine machinery. Today, parts of this water-management landscape belong to UNESCO World Heritage, and the meadows still depend on continued care.

What to do here

Follow the 4.13 km Naturerlebnispfad from the information board near Reiterhof Handermann on Marie-Hedwig-Straße. Pause at the Hermann-Kerl-Hütte and look for the Ottiliae mine’s winding tower. Complete the signed return through the Roseneck allotments; never use the B242 as a shortcut, because it has no pavement here.

For a longer meadow day, choose the tourist office’s 7.3 km Buntenbocker Bergwiesenweg circuit. Use the Kurpark parking area opposite the fire station and allow for the connection to the mapped course. Follow the jumping-goat-and-blue-flower waymarks together with the current route map: there are several shorter variants. Expect a mixture of surfaced stretches, natural paths and narrower trails.

Hahnenklee’s southern accessible trail follows the Schalker Grabenweg towards Oberer Grumbacher Teich. Its published 2.02 km is one way; returning the same way makes about 4 km. There is an initial climb through Rathausstraße and a short steep return section from Café Egerland. Ask about a suitable turnaround before committing to the whole outing.

If you are exploring the southern edge of the park, make the Rhumequelle at Rhumspringe a separate short stop. Watch the spring from the public paths and look for movement on the water’s surface.

Seasonal info

Snow can arrive in late autumn and linger into spring. Wet natural paths need grippy shoes, and stormy weather is a reason to postpone woodland outings. Check the official Harz tour portal and local tourist information for forestry work or storm-related closures. Follow on-site barriers even if your saved map shows a through-route.

Accessibility

The Hahnenklee southern route is promoted for wheelchairs, rollators and pushchairs, but its asphalt-and-gravel approach includes slopes, including the steeper return from Café Egerland. Ask Hahnenklee tourist information about current surfaces, assistance and a shorter start from the Stabkirche parking area. The Clausthal and Buntenbock loops include unsurfaced paths; ask locally about their suitability for your mobility needs. The Oberharzer Bergwerksmuseum is not barrier-free.

Walks and routes

Clausthal-Zellerfeld discovery loop

Follow the story of Josephine and Konrad searching for Tom, a young worker from the mining past. Try the two hands-on stations and pause at the Hermann-Kerl-Hütte.

The route is rated easy for walkers. Its unsurfaced sections mean you should confirm suitability before bringing a wheelchair or pushchair.

Clausthal-Zellerfeld discovery loop

Buntenbock meadow circuit

Use the 7.3 km course linked by Oberharz tourist information. At branching waymarks, compare your chosen circuit with the map rather than inadvertently joining a shorter variant.

The walk is graded easy, but a substantial path section means it should not be treated as a wheelchair route. Ask locally about a shorter suitable option.

Buntenbock meadow circuit

Hahnenklee to Oberer Grumbacher Teich and back

From the Kurhaus, head via Rathausstraße towards the Stabkirche parking area, then follow the Schalker Grabenweg, marked 5G and a blue cross, towards the pond. Retrace your steps.

Advertised as accessible, with important slope qualifications. Confirm current conditions, assistance needs and a suitable turnaround; starting near the Stabkirche parking area shortens the approach.

Hahnenklee to Oberer Grumbacher Teich and back

A discovery-trail morning

Give the Clausthal loop 2–3 hours, including a picnic pause. If everyone still has energy, transfer separately to the mining museum; allow another 1.5–2 hours, longer with a tour.

A slow meadow day

Keep 3–4 hours for the selected Buntenbock circuit and stop whenever a flower or bird catches your attention. A separate Bärenbrucher Teich visit needs its own approach and extra time.

Things to try

Give everyone a turn with the wood

At Clausthal’s wood-weight station, compare the samples before reading the answer. Then try the animal-track memory game. These are trail activities, so no collecting is needed.

Watch one bird, not the whole pond

At a public pond-side path, let each person describe one bird’s behaviour: swimming, diving or resting. You can enjoy the activity even without naming every species.

Find the flower on the sign

Use Buntenbock’s jumping-goat-and-flower waymark as a prompt to look closely at meadow flowers from the path. Leave the grass and blooms for wildlife and the hay harvest.

Understand the ponds indoors

The Oberharzer Bergwerksmuseum connects the outdoor landscape with mining machinery and working life. It is normally closed on Mondays except public holidays. Check before travelling; its show mine is guided-only and the historic buildings are not barrier-free.

Wildlife and habitats

Look at the low heather from the Clausthal trail. Photograph its colour and branching shape without stepping onto the old industrial ground.

Look for the blue-violet flowers beside Buntenbock’s meadow paths. This is the flower behind the jumping goat on the route’s signs.

A quiet forest-edge glimpse is a possibility, never a promise. Stay on the trail rather than following an animal into cover.

At Bärenbrucher Teich, scan from a public path and wait for diving ducks to resurface. A visit here is separate from the featured circuits.

The common merganser is also called goosander. Watch from the public pond-side path; its presence on a particular day is uncertain.

Watch Sumpfteich from its public paths. Keep back from reeds and photograph birds already in open view.

Pause beside Sumpfteich and watch for a bird disappearing underwater. Enjoy the view without approaching the reed margin.

Look from the path at damp edges. Leave frogs and any spawn where they are; a photograph is plenty.

On a mild day, pause beside flowering edges and let butterflies come into view. Avoid following them into the meadow.

Managed upland forest

The Clausthal trail crosses worked woodland. Timber, charcoal production and later planting shaped it; today’s forestry is also responding to drought, storms and bark-beetle damage.

Mountain hay meadows

The meadow-and-pond landscape near Buntenbock combines open slopes, flowers and wet hollows. Watch from the path: these fields are both wildlife habitat and working farmland.

Mining ponds with changing margins

Changing water levels can expose pond bottoms used by specialised plants. An exposed shore is still habitat, not an invitation to walk out across it.

A karst spring

At the Rhumequelle, underground passages deliver water to the surface. Keep to the public paths and leave the spring and its banks undisturbed.

Stories and discoveries

Water that has travelled underground

Some water from the Oder and Sieber sinks into the ground before reappearing at the Rhumequelle. The spring stays around 8–9°C through the year. Its output changes with the weather.

An open meadow needs care

Buntenbock’s meadows began with people making room for livestock and hay. Continued low-intensity farming helps keep them open and flowering. Abandoning them would change the habitat.

When to visit

Change the outing with the conditions

In wet or icy weather, shorten the day rather than forcing a full loop. Keep to designated winter walking routes when snow covers the summer paths, and leave skiing tracks undamaged.

Getting there and practical advice

Use the towns as your base

These are outdoor walks across a broad region. Pick up local information and supplies in Clausthal-Zellerfeld or Hahnenklee; check café and toilet availability for your actual starting point rather than assuming facilities on the trail.

Plan around the walk you choose

For Hahnenklee, look for bus 830 from Goslar and choose a stop for your starting point. For Clausthal’s discovery trail, the published arrival stop is Osteröder Straße. Check the final return service and any extra walk from the stop.

The return matters at Hahnenklee

The route’s accessible label does not mean every section is level. Discuss the Rathausstraße approach and the climb from the café with the tourist office, including whether a shorter out-and-back would suit you better.

Good to know before you go

Take binoculars and spend a few quiet minutes at a public pond-side path. Birds may be far beyond a phone camera’s reach.

Save the exact official route before leaving. The Buntenbock trail has several variants, and the Hahnenklee distance is one way.

For Clausthal, use the parking area near Reiterhof Handermann or plan the walk from the Osteröder Straße bus stop.

Bus 830 links Goslar, Hahnenklee and Clausthal-Zellerfeld. Check HarzBus’s current timetable and roadworks notices before travelling.

Bring water, a picnic, a warm layer and waterproofs. A café or museum opening should be checked separately.

Keep to established paths, leave meadow flowers standing and keep dogs close and under control; follow local protection signs.

Leave pond edges and wildlife undisturbed. Do not feed birds, handle amphibians or enter old mine workings.

Allow for separate museum tickets, transport and any parking charges. The nature park is a large landscape with many starting points.

Frequently asked questions

This is Lower Saxony’s Harz Nature Park. Brocken walks, Torfhausmoor and the Rabenklippe lynx enclosure belong in a separate national-park outing. Do not assume that one protected area’s boundaries or visitor rules apply throughout the Harz.
Choose the Clausthal discovery trail for hands-on stops and a manageable loop. Its story continues at the Robinsonspielplatz elsewhere in Clausthal-Zellerfeld; that playground is a separate visit, outside the 4.13 km circuit.
Yes. The birds, deer, frogs and butterflies described here live freely. Sightings depend on conditions and patience. The pond wildlife notes refer mainly to the Clausthal–Buntenbock pond district, not every lake in the nature park.
Try the Oberharzer Bergwerksmuseum at Bornhardtstraße 16 in Clausthal-Zellerfeld. The indoor displays explain the mining landscape; the show mine requires a guided tour, which also includes outdoor ground. Check hours and tickets. The historic complex is not barrier-free.
