From left to right - the first two photos show the lagoon from the Jameson waterworld and the next three photos shown the lagoon from the St. Laurent waterworld. The Jameson lagoon has a view of the 'swim to' pool, the lake, the patio and the spa; it's more open. The St. Laurent lagoon is tucked into one end of the pool making it more private and intimate. It also is accessible by pool or cave. All rock is natural, trucked in from Arkansas.
