Hochplatte, Mountain summit in Bavaria, Germany.

Hochplatte is a 1587 m high mountain in the Chiemgauer Alps, east of the Kampenwand. Its summit is reached in about two and a half hours from Marquartstein via forest roads, with a final path over the last metres. Since 1973 a 1330 m long double chairlift, the Hochplattenbahn, runs from the valley station at 560 m to the Staffenalm at 1040 m on 17 supports.

The mountain historically marked territorial boundaries between regional areas and the transition between different landscape types. Over time, established trails were developed that made it a recognized destination for hikers.

The Hochplattenbahn, a 1,330-metre double chairlift built by Doppelmayr, has run from Marquartstein since 1973 up to the Staffenalm at 1,040 metres, cutting the climb for walkers. In winter the slopes draw sledgers, and paragliders launch from the mountain. The plant genus Cynoglossum (Hundszunge) long marked its western range limit here.

The summit is accessible from multiple trailheads in the surrounding area, with the eastern ridge offering secured passages for safer climbing. Hikers should come prepared for changing weather and bring appropriate gear for mountain conditions.

The Hochplatte long marked the western limit of the dog's-tongue plant genus (Cynoglossum) in the Chiemgau Alps, a botanical boundary noted in regional flora. Since 1973 the Hochplattenbahn, a 1,330-metre double chairlift built by Doppelmayr, has run from Marquartstein at 560 m up to the Staffenalm at 1,040 m on 17 pylons, shortening the climb for visitors.
