Urban exploring also known as urbex is one of my favorite ways to get to know the neighbourhood.
From closer neighbourhood to farthest one.
It's not only fun trip but also more interesting way to learn about history of place we visiting.
Everytime when I go to a walk I feel like a free man.
For curious visitors who like read books I recommend "Access all areas" by Ninjalicious.
Very inspiring reading where you can gain some useful tips and build your confidence.
