About this spot
Blue Cave on Tanna Island delivers a distinctive cavern dive for intermediate divers looking to explore beyond open water. The site descends gradually to depths between 10 and 25 meters, making it suitable for those with some experience but not requiring advanced technical training. The cave structure itself creates dramatic light play and unique geological formations that draw divers back repeatedly. The dive works as both a skill-builder and a destination dive. Entering the cave system requires good buoyancy control and awareness of your surroundings—standard intermediate-level competencies. The confined space teaches navigation and spatial awareness without the extreme overhead environment demands of deep cave diving. Most dives here are led by local operators familiar with tidal conditions and entry points. Tanna's position in Vanuatu's volcanic chain means the underwater landscape reflects the island's dramatic geology. Year-round diving is possible, though seasonal variations in weather and sea state can affect access and visibility on any given day. The community has documented the site with video, offering divers a preview before arrival. Bring a light—essential gear for any cave dive—and respect the overhead environment. Blue Cave rewards careful, deliberate diving with memorable encounters and solid experience in confined-water navigation.

Preguntas frecuentes
›When is the best time to dive Blue Cave?
Diving is possible year-round at Blue Cave. However, Vanuatu's weather patterns mean calmer conditions and better sea state typically occur outside the cyclone season (November–April). Check local conditions and operator forecasts before booking.
›What depth and difficulty does Blue Cave require?
Blue Cave is an intermediate dive reaching 10–25 meters. You should be comfortable with buoyancy control, basic navigation, and confined spaces. This is not a beginner site and not a technical deep cave. Standard recreational scuba certification is the baseline.
›What marine life will I see at Blue Cave?
Specific marine life observations at Blue Cave are not well-documented in public records. Vanuatu's reefs generally host tropical fish, crustaceans, and invertebrates. Focus on the geological features and cave formations; marine encounters are a bonus.
›Do I need permits or special access to dive Blue Cave?
Tanna is not within a marine protected area, so no MPA restrictions apply. However, always dive with a licensed local operator who knows safe entry procedures, tides, and current conditions. They'll handle any local coordination or fees.
