This is a huge blue hole is located right in the middle of Malo Island’s north facing coastline (directly opposite Aore Island and Ratua Island). It is probably the most natural of Santo blue holes, very cool and refreshing and quite deep. The crystal river flowing out of the blue hole is stunning and leads to a shallow turquoise entrance lagoon framed by a small island (very, very pretty).
You can access the blue hole by catching a boat over to Malo and then asking one of the locals with a 4WD to take you there. Alternatively if you are staying at Ratua Island Resort, the tour desk can organise a kayak trip up the river to the blue hole. Nearly all of Santo blue holes require you to pay an entrance fee to the local landowner (about $5 AUD per person) so make sure to take some cash with you.
