Working with bezier curve, I need to fill the hole at the end I made a rope using a bezier curve.  I then proceeded to use the bevel option to have a rope like thing, but how can I make a real mesh so that I can fill the hole (see picture). Or maybe there's an option for that.
Using a Curve Circle as Bevel Object instead the Bevel Option, you'll be able to toggle Fill Caps on.
