Tappoch? Aye, a bit hidden and worth a visit, we were only there a year or two ago, I hadn't heard of it before that.
Have you been to Rough Castle Roman fort, near the Falkirk Wheel? It's also worth a look on a day you can't get further afield. It's on the Antonine Wall, although the wall itself is really just a slope around there.
