Most of the island's sights are found within the Rapa Nui National Park and if you want to visit most of the moai or locations such as Orongo (where the Birdman festival was held), Ahu Tongariki (the platform containing the largest number of moai) or Rano Raraku (the quarry where the moai were carved), you will need to pay the entrance fee. This costs $63,000 CLP ($80 USD) and can be paid for either at the booth just inside the airport terminal or along Atamu Tekena* in Hanga Roa (a few doors south of the Santa Cruz pharmacy) before attempting to enter any sites. *When I visited, it was only possible to pay this in cash.
