The first is to get a running start (running towards the right side corner of the castle), jump on the castle wall, then on the grass, then back on to nearly grab onto the edge, and get on top of the castle. The second way is to get all of the stars, then a cannon will be accessible out on the front part of the castle. Then, climb into the cannon and shoot yourself on top of the castle.
