Not to show up the previous post by u/Initial-Situation130, but you can actually reach the flying Gyarados with regular pokeballs!
This video is actually from the first few days after release and has been on my switch for years! From what I remember, it took a few tries of slowly inching up the hill until I got to position for it.
I eventually quit the game before finishing the second zone, but started again recently! Now, I'm 80 hours in, rank 9, and haven't gone to zone four yet, but am loving filling the dex and playing at my own explorer-pace!
