Riri Blue Hole is a hidden freshwater gem on Espiritu Santo, often described as the most pristine of the island's blue holes. Access is traditionally gained via a quiet canoe journey up the Riri River, which is lined with dense mangroves and tropical jungle. The water of the blue hole possesses a deep, almost ethereal blue colour caused by the reflection of the sky and the extreme purity of the spring water. Geographically, Riri is located south of Matevulu and belongs to the same hydrological system that funnels water from the Santo highlands through limestone bedrock. The site is less commercialized than other springs, preserving a peaceful and serene atmosphere. Beneath the surface, sunken logs encrusted with moss and algae create a bizarre and beautiful underwater panorama. The local community manages the area sustainably, limiting visitor numbers to protect the ecosystem's integrity. Riri stands as a symbol of Vanuatu's untouched nature and the deep spiritual connection of its people to their water resources.

Parking
Small parking areas are available at the canoe launching points or directly at the land access gate; capacity is limited, so arriving early in the day is advisable.
