I think this is a bug... at first when i finished hoenn and get the waterfall i can't go up here.... then i asked in help chat in game.. they said i need to finish sinnoh before i can use waterfall...

 

now i already finished sinnoh 8 badges and elite 4 i still can't go up here... but i can go waterfall in other places...

I'm also having this issue, though it's the waterfall on the other side of the rocks.

Hello @imafreshbanana, @TrainerKit. Apologies for the extreme delay.

 

These pair of waterfalls are not scalable; meaning you cannot climb them, even with the necessary requirements to use Waterfall outside of battle.

In order to reach the item atop the waterfall, you must use the stairs on the bottom right of the map, cross the bridges, reach the water, and surf to the item.

If you have anymore questions, please let me know.
