I live in Birmingham, UK. It is a very industrial city with many hidden gems! My personal favourite is the Birmingham & Fazeley Canal! It is pretty touristy around the Brindleyplace with its restaurants and tourist attractions. However, it gets more hidden the further you go! So the parts of the canal that are away from the tourists and locals I call hidden gems! And here is the evidence:
The canal is going down, below the roads with heavy traffic and surrounded by the residential building blocks! But it is exciting to witness the historic canal with many gates and even try to open one for yourself!
Here is another image which is tucked away from the main tourist route (I understand that it is not counted towards the contest):
