A lot, actually.
The National Blue Trail is the oldest long-distance route in Europe and takes you through the most scenic parts of the country (Pilis, Danube Bend, Upper Balaton, BΓΌkk, ZemplΓ©n, etc), passing by many historic villages, forests, caves and castles. It's part of the Blue Circle, which is a hike route around the country.
The infrastructure is also very good, with proper markings, trail maintenance, stamps and an official book to prove you've completed the trail, by collecting all the stamps. It's basically an Appalachian Trail lite.
The north has a lot of forests and hidden gems, more experienced hikers actually dislike the blue trail sometimes, since it avoids quite a few nice paths and areas.
But it all comes down to preferences. If coniferous forests and rocky mountaintops are your thing, then the country would be a disappointment for you.
