Taganga is our next destination and we have reservations at Casa Blanca: http://hosteltrail.com/casablanca/
Check out this place, it is $25 for a room for two.
Tucked into a sheltered bay between Santa Marta and Tayrona National Park, Taganga is a relaxed fishing village popular with backpackers due to its chilled atmosphere and cheap diving opportunities.
Little more than a beach dotted with fishing boats and a shore lined with hostels, restaurants and dive schools, this relaxed spot makes a nice break from the trail. http://hosteltrail.com
