Good solo romps in Austria/Germany/Slovenia?

Heading to Slovenia via train from Berlin this summer, I’m thinking about hitting a line or two in the alps while I’m there, but nothing particularly wild. I’d be alone and without much gear so I’m looking more for an alpine scramble than a climb. Something like the rocky bits of fisher chimneys or easier would be sweet, though honestly even a cool hike would be a welcomed recommendation. 

This would be in mid June so it would probably have to be a lower elevation area bc I don’t plan on having much more than some katoolah mini cramps. 

Any ideas where I could start looking for ideas would be greatly appreciated, thank you!

In Slovenia is better to choose some harder routes. Easy routes, scrambling etc. are full of traps. Just now is debate in all media about recent accident where five were injured, none dead. It was in super easy winter route, climbed to late (in April). Scrambling in non winter is on other hand accompanied by loose rock, difficult orientation, etc. Don't become next media star here. 

Via Ferratas are probably a good option! There are lots in the greater Dolomites and many are quite "hardcore," but at least have some degree of safety.
