Moving away from the coast you can discover megalithic stone circles in the prehistoric remains honeycombing the woods and fields around Arzachena. The Nuraghe Albucciu, 2 kilometres southeast of Arzachena, is one of Gallura’s best preserved nuraghi. About 4 kilometres south of Arzachena lies Coddu Vecchiu, one of the island’s most complete 'giants’ tombs'. Nearby you can also find another giant's tomb, Tomba dei Giganti di Li Lolghi, and the Li Muri Necropolis. Regarded as Gallura’s finest example, the "Necropoli di Li Muri" is estimated to date back to 3,500 BC.

Visible from almost everywhere in Cartagena, the Convent of Santa Cruz de la Popa all the way up the a 150-meter hill known as Mt. 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 Mt. 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). An 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.
