The Circe Blue Hole on Espiritu Santo is a remarkable example of Vanuatu’s unique karst hydrological phenomena. This deep, circular freshwater spring is fed by intricate subterranean cave systems, and its water exhibits an intense cobalt blue hue caused by high calcium content and specific light refraction. Ecologically, the Circe Blue Hole serves as a vital habitat for specialized freshwater fish and crustaceans adapted to the cool, oxygen-rich spring environment. Historically, such springs have held great significance for the Ni-Vanuatu people, often functioning as sacred sites for purification or as essential drinking water sources during droughts. The surrounding area is dominated by dense rainforest, with tree roots extending deep into the water to create complex habitats for aquatic insects. Compared to more famous blue holes like Nanda or Matevulu, Circe remains relatively secluded, offering a more pristine and undisturbed atmosphere. Protecting the blue hole necessitates the conservation of the entire inland watershed to ensure the continued purity and clarity of the spring water.

📋 Practical info
Getting there
The blue hole is best accessed from Luganville on Espiritu Santo island via boat or a 4WD vehicle. Local guides know the often hidden paths through the surrounding wilderness better than anyone else.
Best season
The dry season from May to October gives the best underwater visibility and drier walking paths. During the rainy season, trails can be very slippery and the water might become temporarily cloudy.

Surrounded by undisturbed wilderness, the deep sapphire water lies in the middle of a dense jungle landscape. The surrounding ground is often moist and can be quite slippery near the water's edge.
What to bring
Be sure to bring snorkeling gear, insect repellent, and waterproof bags for your valuables. Sturdy footwear with good grip is advisable for the trek through the surrounding forest area.
Parking
Parking spaces are mostly found at the access points of nearby villages or at small boat landings. It is common to leave your vehicle at the official entrance and walk the remaining distance on foot.
Safety
Caution is advised when swimming in the deep water, as there are no lifeguards on duty. Stay on the marked paths to protect the fragile wilderness and to avoid getting lost in the dense jungle.
Time needed
A typical visit lasts about 3 to 5 hours, including time for swimming and relaxing. Those wishing to explore the surrounding wilderness more thoroughly should plan for a full day trip.
