We plan to be in Medellin Dec 16-Jan 3. Hoping to stop in Cartagena, for a week following those dates. I'm discovering that Jan 3-10 are still high season prices. Since our main goal is to sleep in the coastal area, I'm wondering if there are other communities I could aim for, still having access to some of the activities and tours. Must also have access to public transportation. We're senior women, more interested in clean accommodations than glitz. (Hostels with private room, would be fine.) Any suggestions?
