Cave entrance

[Solatso]

I can't seem to find the entrance to the cave where my friends are hiding, I always come out at the same spot whenever a mission ends there but now I can't find it to go back in that way. What part of the island is it on? Thought I found it but the "entrance" is covered by vines and such and I can't get through them. Where's the entrance you typically leave from when completing missions that end in the cave?

Nevermind, found it. I kept missing it when jumping down from where I thought it was, kept falling to far. For anyone else having the same issue it's under the gazeebo near the Dr. Ernharts mansion, there's a path that leads to it but if you fall to the left of the Gazeebo, dont go right, you'll land right in front of it.
