This is a rare find, But well worth going to. It is advertised as a swimming pool, and it is, but behind the swimming pool, right on the beach is a complex of hot tubs. There is a changing room, it is absolutely free to the public. You can sit in the huge thermal tubs and feel the ocean splash up against the side of the tubs! We actually sat there and watched the sun start to set. It is a little hard to find, but if you find the main building with the swimming pool, just go behind it and you will see these spa tubs. pretty amazing that it is right on the beach with the water splashing up on the sides! We went there specifically because it was on the beach, and it was free! Cannot fathom why anyone would pay $80 to go to the Blue lagoon when you have a place like this. You will not be disappointed!
