Playgrounds are top notch hotspots!
That's where I started out, and I'm sure many can say the same. You might not see much at first, but you will see more and more as you train. Just look around when you're going out to find a spot. One wall, one rail, or one fence can mean endless hours of training.
In fact I just finished a quick 30 minute training session on a 4 ft wall near our campus's library.
Just try to visualize anything and everything you can do and that traceur's eye will soon develop

Good luck! I hope you find something amazing
