Although Mount Moon is a Mountain, trainers are not required to climb, when traversing the mountain became an issue, Team Rocket had stepped up and funded a project to interconnect the internal caverns of the Mountain to create a pathway through it for trainers to walk through. In addition to this, Team Rocket had artificial lights installed inside of the cave to prevent the trainers from getting lost within the cave. Although the cave is used to connect Route 3 and Route 4 Team Rocket members are still seen wandering the caves mining for fossils and moon stones as well as other precious minerals.
