History and Background of Millennium Cave

The Millennium Cave holds a deep historical and cultural significance for the people of Vanuatu. It was discovered in the year 2000 by a local guide named Isaac who stumbled upon the entrance while exploring the dense rainforest of Espiritu Santo. The cave remained untouched and hidden for centuries, known only to the indigenous villagers in the surrounding area.


The local Ni-Vanuatu people hold a strong connection to the cave, considering it a sacred site that is deeply intertwined with their ancestral beliefs and folklore. For generations, it has served as a place of spiritual gatherings and rituals. The name “Millennium Cave” was given to commemorate its discovery on the cusp of the new millennium.

Local tour operators have worked closely with the indigenous communities to ensure sustainable and responsible tourism practices, preserving the cave’s integrity and respecting its cultural significance.

Cave Formation and Features

The Millennium Cave is a stunning testament to the power and beauty of nature. Formed over millions of years, the cave showcases a remarkable array of geological features and formations that leave visitors in awe.


The cave owes its existence to the slow erosion of the underlying limestone by water.

Over time, these dissolved minerals have crystallized and formed mesmerizing stalactites and stalagmites.


As you venture deeper into the Millennium Cave, you will encounter towering stalactites hanging from the cave ceiling, created by the slow dripping of mineral-rich water over thousands of years. These formations are a spectacular sight, resembling icicles hanging from the roof of the cave.

As you navigate through the darkness, the sound of rushing water grows louder, signaling the approach of a magnificent waterfall within the cave. These cascades tumble down from the cave walls, adding to the enchantment and beauty of the surroundings.


The cave system is also adorned with stunning crystalline pools, formed by the accumulation of water over time. These pools, with their crystal clear waters, add a touch of tranquility to the journey, allowing visitors to take a refreshing dip amidst the cave’s breathtaking beauty.


One of the highlights of the Millennium Cave is the unique river passage that runs through part of the cave. In this section, visitors wade through the cool, flowing water, creating a thrilling and immersive experience. The river passage offers a different perspective of the cave, providing an opportunity to witness the intricate rock formations up close.


Throughout the cave, you’ll witness the remarkable interplay of light and darkness.
