Solution

We are given this image.

Doing reverse image search on the image didn't return anything meaningful. And so, I tried reading the text on the signpost. The bottom row says "Lukaya Ranger Post", which might be a unique place name. I searched it on Google Maps and got this.

Lukaya Ranger Post is located inside Rubondo National Park, Rubondo Island, Tanzania. This photo validates that "Rubondo Island" is indeed the correct location.
