Vitalhotel Schulenberg · Upper Harz
The Oker reservoir —
close to the hotel.
The lake
The Oker reservoir lies close to Vitalhotel Schulenberg — a rewarding excursion in the area. The lake stretches across 225 hectares, reaches 65 metres at its deepest point and is held back by a 75-metre-high dam wall.
A legend surrounds the Oker reservoir: when the dam was flooded in 1956, the villages of Mittel- and Unterschulenberg sank beneath the water. In clear weather and on a calm lake, so the story goes, you can still make out the church tower far below from the shore — and on misty mornings, hear the ringing of its bells.

What awaits you at the Oker reservoir
Swimming & bathing
The water of the Oker reservoir is clean, cold and clear. On warm summer days, the official bathing spots on the northern shore are an inviting place for a swim in the cool water.
Hiking along the shore
The circular trail around the Oker reservoir runs through untouched coniferous forest, across rocky outcrops and again and again right down to the water. Please note (as of May 2026): the Bramke bridge is currently being rebuilt and is closed — please allow for a detour. Up-to-date information on the alternative route is available at reception.
Stand-up paddling & canoeing
The lake is open to non-motorised watercraft. SUP boards and canoes can be hired in the area. Paddling along the steep slopes is one of the quiet highlights of a stay in the Harz.
Fishing
The Oker reservoir is a recognised fishing water for trout and pike. A fishing licence is required. The still early-morning mist over the lake turns dawn fishing into an experience all its own.
Excursions in the area
Two destinations, one hike
Oker dam
The 75-metre-high dam wall lies at the northern end of the lake. From the crown of the wall you look out over the entire valley and, in clear weather, all the way to the Brocken. The structure is part of the UNESCO World Heritage Site Upper Harz Water Management.
Romkerhall waterfall~45 min (from the dam)
A 64-metre free fall — the highest waterfall in the Harz, created in 1863 for King George V. In spring, the meltwater thunders down the cliff; in winter it freezes into a work of ice art and draws climbers from all over Germany. Free parking on the B498, no admission fee.
Tip for collectors
Harzer Wandernadel
The stamp network of the Harzer Wandernadel (Harz hiking badge) has several stations around the Oker reservoir. Collect all 222 stamps and you earn a bronze badge. The nearest stamp points are at the lake and at the Oker dam — ideal for a first day. The Harz map (app and printed) is available at the hotel.
