Forks is the place where Bella now lives, and where she meets her love Edward Cullen and the rest of the Cullen family.
Forks is a very rainy place. That is the main reson that the Cullens are there; so they don't have to worry about giving away what they really are - Vampires.
Here are some pictures of Forks, and yes, it is very beautiful, despite that it always rains.
