Hohlstein (1,196 m) is one of the most distinctive rocky summits in the Bavarian Forest — a craggy peak rising high above the Reschbach valley, just south of the famous Lusen. Locals affectionately call it 'Großalmeyerschloß' or simply 'Schlössl' ('little castle'), and once you see those rugged rock formations, the nickname makes perfect sense.

A summit cross has stood here since October 2004, marking the top of a peak that rewards every visitor with a sweeping panorama stretching from Finsterau across Almberg, Haidel and Freyung all the way to Rachel and Lusen. The whole area sits within Bavarian Forest National Park, giving it a wonderfully wild and untouched feel. In autumn the surrounding forest turns into a blaze of gold and crimson — arguably the finest season for the hike. Just below the summit, the long-distance trail E6 passes through on its route between Lusen and Mauth.

• Finsterau — marked trail via Tummelplatz (a former Alpine pasture, known locally as 'Schachten'), approx. 2 hours, moderate
• Mauth — marked trail via Tummelplatz, approx. 2 hours, moderate
• Sagwassersäge — marked trail via Tummelplatz, approx. 2 hours, moderate

• The summit lies within Bavarian Forest National Park — stay on marked trails at all times.
• The long-distance hiking route E6 (Lusen–Mauth) passes below the summit.
• Summit cross erected in October 2004.

The name 'Schlössl' — 'little castle' — is said to come from the castle-like appearance of the rock formations when viewed from the valley below, and it is easy to see why the comparison stuck.
