The large and the small Spielberhöhle are close together. The Big Spielberhöhle is not a show cave. Caving in the arbor area requires great experience, fitness and climbing skills.
The entrance of the Großer Spielberghöhle is at 1341 m altitude, it is with about 1200 m total length, the second largest cave after the keyhole cave and with 180 m the deepest cave in Laubensteingebiet.
The cave has next to the large funnel-shaped main entrance, three more shaft-like partly very narrow Tagöffnungen near the entrance funnel, these are hardly to be found on the surface, as they are well camouflaged by the vegetation and its roots. A fourth passage, the water passage, forms a weathered inaccessible connection to the central part of the cave - the water passage. A weathered call connection exists to the neighboring small Spielberghöhle.
The character of the cave is divided as follows - in the entrance area labyrinthine multi-storey corridors - partially spacious corridors with several shafts in the middle part - and Great Gorge and giant camber (terminal block "coffin lid") in the lower area.
The cave is quite dry compared to the keyhole cave, only in the water passage and over the dead corridor there are active channels. However, the cave ices in winter relatively far (up to 15 m shaft / upper quarter). During strong thunderstorms, a lot of water can quickly flood the cave for a short time, a water retention could not be observed. Between 1999 and 2002, two new, previously undocumented corridors were discovered by the "Chiemgau cave bears". parl-webware.de/hoehlen_mitte.htm
