Cartagena Free Walking Tour

Typically, I prefer researching a city and along with Maps.Me organize my own walking tour of a city. This time I didn't have the time to research ahead of time, so I joined a "free" walking tour. It really isn't free. They suggest a $10 donation at the end. But the tour group was too large over 30 people. I was difficult to stay focused while the guide was speaking. Overall, I really didn't care for Cartagena that much. It was too touristy, especially when the cruise boats dock. The other aspect of Cartagena that I was a little surprise was prostitution is legal and there was a lot of it!
