how to meet guys to date?

I (23F) had a serious relationship with my university colleague. After the break-up I went on tinder and had 4 short dating moments (between 1 month and 3 months) but they never felt in love with me or anything like that. After that I just went silent for 1 year and completely lost my interest in guys. In the past month my feelings came back to life and now I’m ready for a relationship. And I really want one. But I don’t know what to do. Right now I’m on summer vacations. I’m planning to go to some music festivals and travel. Besides that I’m completely free until I go work in September. Can anyone advice me where and how meet guys? Should I go on tinder again? Try to talk with someone at the parties? I consider myself smart and pretty but for some reason I’m not having a lot of luck. The guys that like me I don’t like them, and the guys I like are already taken or the things just don’t work out.
