If you're lucky, you'll see sea lilacs, a plant with purple flowers that covers the beach in summer. It is a rare and magnificent spectacle that will make your hike unforgettable.

In August 2022 it is far too dry. Many of the bodies of water have dried up.

Anyone who wants to observe the cormorant colony needs binoculars or similar. Cormorants reach a body size of 80-100 cm and a wingspan of 120-150 cm. They are excellent divers!
