Reserva del Regajal-Mar de Ontígola

The Regajal-Mar de Ontígola is a wetland with lakes, marshes, and salt water bodies that stretches across a large area south of Madrid. The place consists of open water surfaces, dense reed beds, and low Mediterranean scrubland that together create different habitats for water animals.

The lagoon system was created in the 16th century as part of royal plans for the area to attract birds. The reserve's structure preserves these historical water systems and was later transformed into a protected natural area.

The reserve draws nature enthusiasts who combine bird watching with walks through varied habitats. Visitors can observe how water and land interact to support the animals and plants living here.

The area has marked paths and viewing points where you can watch birds and other animals. It is best to visit early in the morning and bring binoculars for the best viewing experience.

This area is home to one of Europe's largest butterfly concentrations, with many species found nowhere else. The marshes and lakes create perfect conditions for these colorful insects, which fly in large numbers during the warm months.
