From Bulbapedia, the community-driven Pokémon encyclopedia.
The Mirage Cave (Japanese: マボロシ洞窟 Phantom Cave) south of Route 107 is a Mirage Cave in Hoenn in Pokémon Omega Ruby and Alpha Sapphire. It is only accessible by soaring on LatiasAS or LatiosOR.
One random daily Mirage spot appears daily; more Mirage spots can appear due to StreetPass, but these additional Mirage spots will not have hidden items.
Each form of Unown in this area has the same encounter rate.
