Advice on finding mountain hares

Just wondering if anyone has any advice on finding mountain hares?  My aunt and brother are going skiing next week and I'm going up with them to see if I can find some wildlife and I would love to see a white hare!  Last time I was up I was following tracks, but found no hare, until we were driving away from the ski slopes to see a normal coloured hare say at the side of the road!  I'll have my dog with me so maybe she'll be able to pick up the scent of one for me lol
