When I travel I like to get to know the local people rather than spending all my time with other tourists.

Does anyone know any activities I can participate in so that I can meet the Granadinos.

I am going to be in Granada for 1 month

Couchsurfing

It may be a good idea to join couchsurfing.
This is a good way of getting to know the locals.
