If you click *this link*
, you will see a map of Hyrule. Now, the place you seek is located in the spot where Poe 32 (P-32) is on the map.
Do you have the warp point at Zora's Fountain = the Zora throne room? The highest point on the map? It's just above where you want to be. If you warp there, you should be able to get there through Zora's Domain (with the waterfall) fairly quickly, just follow the right flow
And oh, close to IZA's hut you will fight some Shadow Beasts so you will have a warp point right there, too. Good luck!
