NCP is an island company with Rapa Nui guides, which on an island where a guide is legally required is the distinction that matters — the person walking you round Rano Raraku is from the community that owns it. They collect you from wherever you are staying and bring you back, and if you book several tours they arrange them so you do not see the same site twice.
A half day is 50,000 pesos a head, a full day 60,000, and the "Experiencia Completa" that strings the island together across several days is 200,000. The sunrise at Ahu Toŋariki — fifteen moai with the sun coming up behind them — is its own 50,000-peso trip and is the one people remember. There are separate tours to the lava tubes, Ana Te Pahu and Ana Kakenga, and private itineraries on request.
Everything is booked on one WhatsApp number, and every button on their site opens a message already naming the tour and its price.
