This map was originally created a few years ago as an open-access LAN world at my school. One day, my friends and I decided to crate a giant area of TNT and blow it up, which created a monumental crater. About a year later, I found this map again, and wondered if I could climb all the way to the top of the crater in Adventure mode with parkour. Amazingly, I was successful in this, completing the ascent in just 25 minutes the first time, and now my fastest time is about 15 minutes. The path of the course is 100% created by TNT; I have not made any changes to the map at all. Because of the lack of editing, no rough edges in the course have been smoothed out, meaning that you might have to backtrack sometimes to find the right path. While it might often seem that there is no possible way up, I can assure you that there is; it just takes a little time to find it. The goal is to get to the beacon on the surface. You can play this course in easy mode (creative mode so that you can fly back up if you fall) or hard mode (adventure mode so that if you fall you will die and will have to start over). Let me know what you think, and have fun!
