It is a beautiful place that is quite cool even in the heat because it runs along the Yvette and several ponds, but it concentrates a lot of people on Sundays on a fairly narrow path. In high season, prefer Saturday for this course

The Latona basin results from the desire of Louis XIV to create, in the center of his Garden, a fountain which recounts the childhood of Apollo, the sun god he chose as his emblem. To create this fountain, Louis XIV transformed a pool dug by Louis XIII by gradually installing water features and decorations sculpted by the Marsy brothers. The Latona basin went through several states before adopting its current form. In 1667, it was the Toad Fountain. From 1668 to 1670, a first Latona basin appeared; Latona is then at the same level as the other figures and turned towards the Castle. From 1687 to 1689, Jules Hardouin-Mansart created the current pool, by making Latona turn around and hoisting her to the top of a marble pyramid. http://latone.chateauversailles.fr/page/le-bassin-de-latone/histoire-du-bassin
