Ses Salines Natural Park
Shared between the southern tip of Ibiza and the northern edge of Formentera, the Ses Salines Natural Park is a UNESCO World Heritage wetland that turns rose-gold at dusk — its salt lagoons tinted pink by halophilic algae and, between April and October, flecked with actual flamingos.
The salt lagoons up close
The Formentera side of the park centres on Estany Pudent and Estany des Peix, two brackish lagoons connected to the sea by narrow channels. A flat cycling and walking path rings Estany Pudent — a 10 km loop that is one of the finest easy nature walks in the Balearics, with unobstructed views of the lagoon and the dunes beyond.
The salt pans themselves were worked commercially until the 1980s and the old infrastructure — wooden sluice gates, rusted machinery, salt-crusted embankments — gives the landscape a quietly industrial beauty alongside the wildlife. Over 210 bird species have been recorded here.
Wildlife and best timing
Greater flamingos are the headline act, but patient walkers also spot Audouin's gulls, ospreys, black-winged stilts and, in spring, purple herons nesting in the reeds. Dawn and dusk are the most productive hours — bring binoculars.
The park also protects the Posidonia seagrass meadows that make Formentera's water so clear. Information panels along the lagoon path explain the ecosystem in English, making this a genuinely educational stop that children tend to enjoy as much as adults.
