Granada is Spain's hidden gem. Nestled among the mountains, it was the last Muslim stronghold in Spain and retains a lot of the Islamic culture. It is walkable, hikeable and is a nature lover's dream. It is also known for huge, delicious and FREE tapas! I recommed Umm Kalthum on Jardines Street near the Cathedral. Don't forget to visit the Alhambra while you are there! After 5 years living in Spain, Granada will always have my heart.
