Blue Hole Two is a giant hole in Tanna's reef system with tunnels and swim-throughs leading out to the open reef. Divers pick their own way through the passages, and the tide decides whether it is reached from the beach or by boat.
Also known as Blue Hole 2.
Where it is and how deep
No published position for this site — the map shows Tanna & Lenakel and its other sites; operators know the mooring.
The dive
The hole itself bottoms out at about 6 m. From there several tunnels and swim-throughs lead out to the outer reef, and part of the dive is deciding which route to take through them. Once outside, the outer reef reaches about 20 m.

Questions divers ask
Is Blue Hole Two a shore dive or a boat dive?+
Both, depending on the tide: at low tide divers walk in from the beach, and at high tide a short boat ride takes them to the hole.
