Good place for hanging out with your family and your friends especially for children because they can learn a lot from this part not only the trees but also the animals all over the world. The park is pretty big which is divided into many areas with different climates for the habitats can survive. You could find a small jungle in tropical countries or a desert with a lot of cactuses in Arizona US, hunting plants in Africa, some kind of snakes which is very poisonous in the world, some giant crocodiles, elephants, buffalo, monkeys, gorillas, tiger, cougar and many many exotic breeds that I can not name because they are so weird and I haven't seen them before while I am an adult so it is such a great idea to take your children there or even your friends, parents, the older one because i think there are many things will be new to you. In the Korean perspective, You could find a romantic tree-lined roads around the park where you can take some gorgeous pictures and the best moment is in the autumn, in the end of October the leaves will be fallen, creat a deeply romantic scene. There is a lake with kind of lotus flowers (I am not sure) and Koi fish, It looks great too. The entrance ticket 1000won for the train from the main gate to get inside. 5000won to enter the park for sightseeing and taking pictures. One more recommendation is that you should bring the food inside for picnic in the park. It is not a bad idea because the food in the restaurant inside is quite expensive and not good at all
