Cairngorm Reindeer Centre
Reindeer in the Wild

See Britain's only wild herd of reindeer either solo or on a daily guided walk at 11am. The herd is based around 150 animals, reintroduced into Scotland in the 1960s.
Good footwear is advisable for the 20min hike to the herd. If that sounds a bit much or the weather looks threatening, you might content yourself with the few members of the herd that browse around the paddock by the centre.
