FATMAP difficulty grade
This loop is in 3 parts - Merritt's Nature Trail (up to the plateau), Dead Horse Gap Trail (follows the ridge) and Thredbo River Walk (flat).
The only strenuous part is section 1 (Merritt's, 1.5 - 2 hours uphill).
Fairly open country and nice variety of ecology and terrain.
Take care with changeable weather conditions (from blazing sun to icy winds possible).
No special gear needed.
