Apart from bustling nightlife and the bat cave of Pablo Escobar,  Medellín has some interesting sites worth visiting in the day. 

As mentioned earlier, grab a taxi driver for the day and he will also act as a tour guide.

Comuna 13 is a district similar to the favelas of Rio, and visitors would normally go down there without the A-team. Historically, this area was known to be the most dangerous in  Medellín. However, it has undergone a complete transformation in recent years and relations between local artists and the government have made a visit here a safe and exciting experience. 

Enjoy the amazing street art, see the armoured guards on patrol, and even a small shrine to Bill Clinton at a shop he went to. 

The Local Science Park, the Aquarium, and the Zoo also provide a good day out - here are some unusual pictures to view.
