Eisberg is a quiet, forest-cloaked hill rising to 330 metres in the Eastern Upper Lusatia region of Saxony, Germany. What makes it special is its volcanic origin — the summit dome was formed when nephelinbasanite lava welled up through an ancient volcanic vent and solidified, creating a distinctive rounded hilltop. It is a rewarding little detour for anyone interested in geology or simply looking for a peaceful woodland walk.

Today the entire summit and the slopes of Eisberg are covered in a dense sessile oak forest interspersed with thorny scrub, giving the hill a wild and unhurried atmosphere. In summer the canopy provides welcome shade, while autumn transforms the oaks into warm shades of copper and gold. Directly next to Eisberg, just 400 metres to the southeast, stands the neighbouring hill Langer Berg, making the two a natural pair for a short combined outing. The hill sits right alongside federal road B178, west of the village of Großhennersdorf, which makes it very easy to reach by car.

• Großhennersdorf (roadside on federal road B178) — the hill rises directly beside the road on the western edge of the village; the walk up through the forest is short and straightforward, difficulty: easy.

• The summit and the former quarry sites are completely overgrown with oak forest and scrub — there is no open viewpoint at the top itself.
• Combining a visit with the nearby Langer Berg hill (approx. 400 m to the southeast) is an easy and worthwhile extension.

In centuries past, two stone quarries operated on Eisberg's slopes, supplying building material to the surrounding villages — today the forest has reclaimed every trace of that industry, leaving only the volcanic rock beneath your feet as a reminder of the hill's eventful past.
