The whole surrounding area is spectacular. The ancient trade route has long sense been abandoned but traces of the old road are still around (often times grown over with trees). The lake is full of frogs and snakes, neither of which are dangerous. Don't be intimidated by all of the water snakes (literally you'll see hundreds) they are harmless so go ahead and go for a swim.
There is an old bridge that was used for the trade route that is very impressive.
They may be hard to find, but there are some abandoned fortresses well away from the town that are interesting to explore. In anycase, if you can't find the fortresses you are sure to stumble on something else interesting.
