Hoys are located at Dinner Plain, Harrietville and Mt Hotham. They also have an arrangement where you can pick up / drop off snow chains at Harrietville and Omeo if passing through the Alpine Way.
We have been doing skiing trips for quite a few years and last week was 1st time we used Hoy's for snow chains. 1st class prompt service and even assistance with putting on the chains halfway up the mountain. Highly recommended.
