In Pokémon Brilliant Diamond and Pokémon Shining Pearl (BDSP), players can make use of hidden moves in their venture to fill their Pokédex and fully explore the region of Sinnoh. One such Hidden Move is “Waterfall“. ‘Waterfall’ Hidden Move allows you to climb up waterfalls from the surface of the water. This will help you to access previously inaccessible areas and also makes navigation through the region much easier in the endgame.
How to Climb Waterfall (Hidden Move)
To get the ‘Waterfall’ Hidden Move, first, you will need to defeat Sunyshore City gym Leader and get the eighth badge (Beacon Badge).
Now go north from the Sunyshore City Pokemon center until you reach the beach area.
On the beach, you will find a girl named Jasmine. Talk to her and you will get TM99, which will give you the ‘Waterfall’ Hidden Move.
