My favorite spots were on the way to Fortree city where you had to surf then use waterfall to get to a little hidden corner. That, and the area in Whisper? Tunnel where you go outside and find blackglasses
This was my favorite generation. I spent countless hours exploring and finding better hidden secret bases. The only thing I didn't like about X and Y was how little there was to explore. The battle Frontier was the best post game they've ever done too.
