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. It is situated near a river by Volley Town and is located between Fortree City and Lilycove City.
It got its name because it looks like a Camerupt's humps. At the summit is an open area where people can enjoy stargazing. In Crazy as a Lunatone, Ash and his friends scale 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 catch some moonlight to regain its energy and fly back into space.
