You understand the second there all right, it shows the place.
What is important to understand that the first there is something completely different. Although it uses the same word letter by letter, it has nothing to do with places like there and here.
Most languages have various constructs to specify that something exists. There is and there are are the forms English uses for that. The following sentence will be grammatically incorrect but it will make you see the structure clearly:
*They exist a lot of charming forest areas there.
Surely, we can say that in a way that's correct:
A lot of charming forest areas exist there.
So, using there is or there are simply states that something exists. Consider it a fixed, compound structure that has its own meaning, not the meaning of the two words it's made of. And this means that if you want to describe a place in your sentence with a there or here, then yes, you have to add that separately, independent of this fixed structure.
