Jona-There is no practice area, as such. There is a practice mode that duff referred to but the best thing you can do is play anywhere you like and practice whatever you like-just don't finish the round. You can do this as often as you like.
BPB#2 has a big flat green that's good to putt back and forth on, as an example. From the green on any hole you can aim backwards to get back to the fairway, or hit into a trap on purpose to practice getting out then hit back into it. You have 10 strokes per hole before you max out. GL
