The caves are renowned worldwide as the location for the Brooke Shield's film from the seventies, titled the 'Blue Lagoon'.

The Blue Lagoon Caves and other caves on Sava-I-Lau such as the manulevu (falcon) caves and prawn caves are also famous locally for their Fijian legends and also sacred Fijian mythology.

The Blue Lagoon Caves are the resting grounds of the great ten-headed god of Uluitini. Each chamber of the caves represents each of the God's nine snake-heads and one like human head. It is said that the God's central human face possesses an angelic beauty that is almost too much for any mortal's gaze to behold and embedded in the God's forehead is a shimmering diamond like stone, which is source of the great mana.

You can just make out the silhouette of the ten heads while in the caves but rest assured the ever-hospitable God has already vacated the premises for the comfort of the mortal guests. The caves are also home to Dema Leka and Damu Balavu (two fish) as well as a Donu (eel) that have lived there forever without ever breeding, changing, growing or dying.

One of the chambers within the Blue Lagoon Caves is said to be the pregnancy cave. This cave can be entered by everyone of any shape or size except a women who is pregnant and is concealing this from everyone. Even the slimmest pregnant woman will get stuck either at the mouth or the cave or the tunnel entrance.
