Can someone help me finding an old but really cool map I owned?

[Nytrogod]

I downloaded it from garrrymod.org like 2 years ago or something. It was like this: I started at some kind of dock with some boats on it, then I climbed a little staircase and I would have a building in front of me, kinda like an hotel, and it had a room on the top level, with a porch and eveything. Then, it had a pretty big roadway with tunnels and everyting, and you passy by a beach and that and you would continue down the road and would get to the hotel again. It was sort of an island. I loved that map but can't seem to find it anymore. Can someone help me?
