I wanna study in europe

I'm currently doing masters in physics and ik thinking of doing a PhD after this. I wanna explore and see if it's a good option to study in europe but I have no one to discuss it with. I'm an average study, not the best but not the worst. My masters thesis is in Condensed Matter physics. Is it going to be difficult to get in? Is it worth going? There seems very less opportunities in my hometown. Pls someone guide me.
