Ladder Falls are on Ladder Creek just before it flows into the Mersey River at Lees Paddocks, Tasmania, Australia. These are several hours into the Lees Paddocks Track, which enters the Cradle Mountain-Lake St Clair National Park. It is possible to walk to the falls and back in a day from the car park on Mersey Forest Road, although it is a 9 hour return walk. This video also contains the side trip to Oxley Falls on the Mersey River.
