Chocograph place

Im doing chocobo side quest and i recently got chocograph: Abandoned Lagoon. However i cant get to it because i cant get to the shallow water place from any beach. There is a small beach and some tracks next to the place where the treasure is but no where to land Hilda Garde.

What do i do

Anyway, there’s no situation where you need the Blue Narciss to get it. There should be somewhere to land from which you can get to it.

I was able to get to it by getting a mountain chocobo. The chocograph said only reef was needed to get it but it probably meant that u also had to have The Invincible

Thank You for ur Advice
