How To Obtain HM07 Waterfall

Within Pokemon FireRed, there are seven different HMs (Hidden Machines) to obtain during your journey. HMs work a lot like TMs in that they are moves that can be taught to your Pokemon; however, unlike TMs, HMs last forever and even can be used in the overworld. Obtaining all of the HMs will also be vital, since you won't be able to complete the entire Main Story & Post Game without them.

HM07 is none other than the move known as Waterfall. HM Waterfall can be found deep inside Icefall Cave on Four Island. HM Waterfall will allow you to travel up waterfalls found across the Kanto Region. You will actually need HM Waterfall to make it up the waterfall found in Icefall Cave in order to defeat Team Rocket within the cave.
