Adaminaby /ædəˈmɪnəbi/ is a small town near the Snowy Mountains north-west of Cooma, New South Wales, Australia, in the Snowy Monaro Regional Council. The historic town, of about 234 people, is a trout fishing centre and winter sports destination situated at 1,017 metres (3,337 ft) above sea level. Economic life is built around tourism and agriculture–the town serves as a service point for Selwyn Snowfields and the Northern Skifields. It is also a popular destination for horse riders, bushwalkers, fly-fishermen and water sports enthusiasts as well as a base for viewing aspects of the Snowy Mountains Scheme.
Adaminaby is one of the highest towns in Australia, and snowfalls are not uncommon during winter. The historic Bolaro Station and scenic Yaouk Valley are located near the township and Charlie McKeahnie, said to be the inspiration for The Man From Snowy River, a poem by Banjo Paterson, lived and died in the district. Later, Nobel winning author Patrick White wrote about the town. The construction of nearby Lake Eucumbene made it necessary to re-locate the original Township of Adaminaby in 1957. In times of drought, the original township and relics of the old valley re-emerge from under the waters of the lake. The present township is located on the Snowy Mountains Highway and is known as the "Home of The Big Trout" and the location of the Snowy Scheme Museum.
