The village is surrounded by a very tall and long wall, that would be very hard for someone to walk up and down on to get around, considering there are no trees around it. Trees can be found inside, but outside because the mist village is surrounded by a large lake, there is no place for trees to grow. The only place one might be able to attack from was behind the village, where there are very tall mountains and such. In anycase, upon walking through the entrance to the village you walk down a hill area, because the mist village is somewhat located in a large whole of sorts which is why there are many hills around it. Just walk down until there is only one way to go, since a strip of land is the only way into the village. You will be stopped by guards and asked the questions needed. After that, come in and have fun.
