If the weather's not playing nicely, why not head to Historical Museum? You'll be fascinated by just how much you can learn about days gone by here.
Situated in Smolyan, this collection of historical artifacts is well worth a look. But you'll find tons more to see in the area. Pamporovo Ski Resort, Smolyan Lakes - Snezhanka, and FunPark Pamporovo aren't too far from Historical Museum.
