Dangerous Cliff (Japanese: キケンながけ Dangerous Cliff) is a location in Pokémon Ranger: Guardian Signs.
It is located east of Tilt Village on Mitonga Island and can be accessed via a cave in Tilt Village. During their first visit there, players must go through the cliffs under a certain time limit. The player must make many precise jumps while riding Raikou to get through the area.
