Just down the road from Kilmartin Glen, at Knapdale, is possibly the worst-kept secret in Scottish wildlife circles: Beavers were introduced here in 2009 and can regularly be seen on Loch Coille Bharr.
This whole area is covered in Atlantic Rainforest, which is the perfect habitat for the huge variety of mosses, liverworts and ferns which form the basis of this place's incredible biodiversity.
It's worth stopping by the Argyll Beaver Centre to learn more about this area from Oly and Pete. They also run guided walks which are definitely the best way to see the beavers.
These days, the southern boundary of Kilmartin Glen is formed by the man-made Crinan Canal. Famously described as Britain's most Beautiful Shortcut, it was built in the early 1800s to allow ships to bypass the Kintyre Peninsular and the treacherous waters of the North Channel.
Further south past Knapdale, you'll come to the pretty village of Tayvallich, which has a pub serving excellent seafood dishes. At the end of this peninsula is the tidal island of Danna, which has possibly the best views across to the stunning Isle of Jura.
