The first and closest, Matevulu, is the largest of Santo blue holes and is only a short 45 minute paddle away, directly opposite Oyster Island Resort. Paddling up the crystal river to reach the swimming lagoon is an experience in itself – like being lost in the Amazon! It takes about 30 minutes to paddle up the river (you can also drive direct to the blue hole – just follow the signs from the highway). Once at the blue hole you are rewarded at the end with a great swimming area and a giant rope swing tied onto a large banyan tree. There are also toilets there.
Cost is 500vt per person. Note – lately, this particular blue hole has become turbid and not as clear as it once was (perhaps due to a drought which occurred in 2016) so please check with locals/tour guides on arrival to find out its condition.
