Els Ullals de Baltasar are points of groundwater upwelling , originated from the rain that falls in the nearby limestone mountains of Montsià and Els Ports. When the aquifer from these mountains reaches the Delta, it collides with the clayey and impermeable materials, emerging towards the surface and creating these pools with a typical circular or eye shape, from which the name comes. The Ullals stand out for their peculiar flora where the surprising white water lily stands out, but also for its wildlife, with the important presence of various iberian endemic fish species, such as the Valencia toothcarp, or in danger of extinction, such as the three-spined stickleback. The visit contemplates the discovery of this Ullals environment full of peat bogs and riverside forest guided by Ramon Vidal.
