From Bulbapedia, the community-driven Pokémon encyclopedia.
Camerupt Point (Japanese: バクーダの丘 Bakuuda Hill) is an anime-exclusive location in Hoenn, which was featured in Crazy as a Lunatone. It is situated near a river by Volley Town.
It got its name because it looks like a Camerupt's humps. Its clear view of the sky makes it a perfect location for people to enjoy stargazing. After Nurse Joy's recommendation, Ash and his friends headed towards Camerupt Point to help a Lunatone being chased by both Team Rocket and the Pokémon Mystery Club. With both Team Rocket and PMC out of the way, Lunatone was able to absorb some moonlight to regain its energy and fly back into space.
