Arrived in Cartagena last night after a 3.5 hr flight from Leticia. The taxi ride to the hostel was short (10 minute) but expensive ($7.50). The Hostel El Viajero Cartagena is within the historic and walled portion of the old city. Today I hiked along the wall of the old city and took pictures of all of the old structures which have been maintained well. 3 more nights here and then to Santa Marta for 2 nights.
