Inland, there are many balnearios, bathing places with swimming pools, often centered on hot springs in picturesque surroundings. It is very common to find these water parks in particular in the Morelos state (around 26) where the climate is very pleasant. Most of them are natural springs and they go from parks with ecological conservation and protection like Las Estacas where people can practice scuba diving, up to modern water parks with toboggans and waves like El Rollo, "Oaxtepec", and "Temixco."
