Tourism near Jesenik, Zlate Hory - need some directions

[TnT84]

Well I'll probably be near Czech border next weekend and wanna jump to your country for few hours. I'll be near Jesenik, Mikulovice, Zlate Hory. So the question is where to go? What interesting I can see there. I know Biskupská kupa, jeskyne na Spicaku (or something similiar), Lipove Lazne, Zlatorudne Mlyny and few other places nearby ( I mean I saw it already). I wanna visit Jeskyne na Pomezi, is it worth of it? Are there any castles? Any ideas what else to visit?
Thanks for any reply.
