This island is found on the northwest of the Copacabana peninsula. The legend of its origin says that the Sun and Moon took refuge in the Karka or sacred rock, which was the first place to receive the sun rays. The legend says this was the birthplace of the first Incas, Manco Kapac and Mama Ocllo, children of the Sun and founders of the Inca empire.
Yumani is the main port in the south part of the island, it has a large precolombine stairway which goes from the port to a fountain high in the island. This fountain is made of three springs which many say represent the three laws of the quechuas, Ama sua - don't stea, Ama llulla - don't lie and Ama kella - don't be lazy. You many continue to the small village of Yumani, above the fountain.
The inca palaca of Pilkokayana is below Yumani, the structure once had two floors but only one remain, it is made of several rooms. The palaca seems to contain both Inca and Aymara architectural elements and is preserved enough to be an interesting sightsee.
