The slope is unique in the sense that it uses a special tube sled that is much safer than the traditional plastic sleds. It is also much less likely that the sled rider will wet their clothes with these sleds.
In addition, the slope is located near the Seoul Olympic Park. The Olympic Park is one of the most scenic, famous and largest parks in Seoul, if not Korea, and is definitely worth a visit even if not for the fact that there is a snow slope there. So why not take this opportunity to visit Olympic Park and kill two birds with one stone?
