Visible from almost everywhere in Cartagena, the Convent of Santa Cruz de la Popa all the way up the 150-metre hill known as Mount Popa. The hill got its name for resembling a poop deck of a ship. After four centuries of varied history, the convent itself is now open as a religious museum. From the top Mount Popa you’ll get the best panoramic views of Cartagena and its beaches. The fastest and least stressful way up the hill is with a taxi (be sure to haggle on the price). Important tip: if you take a taxi or a car service to this location, pay them a few pesos to wait for you to drive you back. The taxis on top are all already "reserved" and Uber drivers are not eager to drive all the way to the top to pick you up.
