Mount Geryon is a mountain in the Central Highlands region of the Australian state of Tasmania. The mountain is part of the Du Cane Range and is situated within the Cradle Mountain-Lake St Clair National Park. With two peaks, Mount Geryon North has an elevation of 1516 m above sea level and is the twelfth-highest mountain in Tasmania. Mount Geryon South, with an elevation of 1509 m above sea level, is the state's fifteenth-highest peak. The mountain is a major feature of the national park, and is a popular venue with bushwalkers and mountain climbers. It has more than 40 ascent routes for climbers, some of which are over 300 m in height; however, it is the impressive east face at 500 m in height for which Mount Geryon is most popular. There is a famous nearby tarn which is known as the Pool of Memories.
