If you're looking for a history documentary on Scotland, this is not the program you want. On the other hand, if you want a bit of scenery, some lesser-known facts about popular tourist areas, a dash of local colour, and an absolutely delightful host, you'll love Secret Scotland.
Thus far, the show has taken us to Edinburgh, Stirling, and St. Andrews (along with a few assorted small towns in the surrounding areas). Even as an American, I've been to many of the sites Mrs. Calman visits - but I love that she highlights some of the more unique and unusual aspects of the locations. It makes me want to go back, even though there are still so many UK destinations I've yet to visit a first time.
Episode 3 goes up to Loch Ness, and I'm probably most excited for that one. The endearingly-eccentric Nessie expert Adrian Shine makes an appearance, and I'm more than a little jealous of the host for getting to meet him.
If you enjoy a bit of Scottish scenery presented by a host who just radiates kindness and general pleasantness, definitely check this one out.
