Description
Embark on a captivating half-day trekking tour to explore the volcanic cave systems that once served as vital shelters and ceremonial spaces for the Rapanui people. With your private guide, step off the main tourist trail to discover the mystical beauty and archaeological richness of Easter Island’s most impressive caves.
Begin at Ana Te Pahu, the island’s largest cave, featuring a vast lava tube system with four chambers once used for cooking, shelter, and survival. Its entrance is lush with banana trees, earning it the nickname “Cave of the Bananas.”
Next, visit Ana Te Pora, a smaller volcanic cave with deep ceremonial importance and easy access from a nearby parking area. Continue to Ana Kakenga, famously known as the “Cave of the Two Windows,” with two dramatic ocean-facing openings formed by lava flowing into the sea. The cave stretches about 50 meters and offers stunning coastal views.
The trek concludes at Ahu Te Peu, an unrestored archaeological site where toppled moai, ancient village remains, and the island’s longest hare paenga (boathouse) can still be seen in their original state. According to oral tradition, this site was once the home of Ariki Tu’u Ko Ihu, a revered chief.
