The '''Cavern of the Metal Cap''' (called the '''Metal Cap Switch Course''' in the message that appears upon the player entering), or '''Metal Cap Cavern''',<ref>M. Arakawa. ''Super Mario 64'' Player's Guide. Page 59.</ref> is a cave that contains the [[Cap Switch|Metal Cap Switch]] in ''[[Super Mario 64]]''. The entrance is located in the [[Hazy Maze Cave]], behind a set of double doors in the Underground Lake area. It is the only [[level]] to be entered inside another level in the N64 version, and one of the only two levels to be entered inside another level in the DS version, the other being [[Big Boo Battle]] in [[Big Boo's Haunt]]. In order to reach it, the player must traverse to the underwater cavern in the Hazy Maze Cave. The player then has to get on top of [[Dorrie]]'s head and then steer him over to the small patch of ground outside the double doors. Upon entering the double doors, the player has to go through a short hallway, at the end of which is another pool of liquid metal, much like the one that is used to enter the Hazy Maze Cave in the first place. Falling into it transports the player to the Cavern of the Metal Cap.  

In ''[[Super Mario 64 DS]]'', the area was retitled '''Behind the Waterfall''', and the Cap Switch was removed. However, a second [[Power Star]] was added, which can be reached only by [[Mario]] using a [[Power Flower (Super Mario 64 DS)|Power Flower]]. Signs, however, continue to refer to the area as the '''Metal Cave''' or '''Metal Cavern''', which is a holdover from the original version.

===Grab 8 Red Coins<ref>M. Arakawa. ''Super Mario 64'' Player's Guide. Page 82.</ref>===

There are eight [[Red Coin]]s to be collected here, and several of them are just below a huge waterfall leading into the river. The player can reach them by becoming Metal Mario (Metal [[Wario]] in the remake). However, the player can [[Ground Pound|ground-pound]] on specific parts of the river to collect the Red Coins. Once every Red Coin is collected, the Power Star appears at the [[Star Marker]] underwater near the waterfall at the back end of the cavern, surrounded by a circle of [[Coin|Yellow Coin]]s.
