I visited Caithness last week and had two excellent morning stalks for does with 'levigsp' (trade member on this site). He is very knowledgeable about his resident roe population and anticipates their every move. This is the most Northerly stalking available in the UK and extends up to Dunnet Head. The terrain is relatively flat and the roe were seen not only in the fields and farmland but even on the open moor. He has a large, detached hunting lodge available for rent - I didn't stay there but had a guided tour and it is superb inside and perfect for a large group or family. In addition to the Roe stalking he told me he has some red and sika available and also goose shooting.
I had a very relaxed and informative two mornings with him and I would thoroughly recommend a trip north to experience this unusual landscape. The drive is worth every minute.
