About Budapest
Budapest is Europe's best-kept secret for partying, thermal baths, and ruin bars. Széchenyi Baths are touristy but iconic (drink beer while soaking), the ruin bars in District VII are post-apocalyptic nightlife, and the Danube views from Fisherman's Bastion are unreal. Cheap, beautiful, underrated.
- •Széchenyi Thermal Baths (bring a swimsuit and beer)
- •Ruin bars like Szimpla Kert in District VII
- •Buda Castle and Fisherman's Bastion for views
- •Great Market Hall for Hungarian street food
