The Arles region is a gateway to several significant protected areas. The most prominent are the Réserve Naturelle de Camargue, a vast wetland reserve, and the Réserve naturelle des Coussouls de Crau, which protects a unique steppe landscape. Other notable reserves in the area include the Réserve naturelle de la Tour du Valat and the Réserve Naturelle De L'Ilon.
The nature reserves around Arles feature two primary types of landscapes. The Camargue region is characterized by a mosaic of salt marshes, reed beds, sandy dunes, and large brackish lagoons like the Étang de Vaccarès. In contrast, the Crau region presents a semi-arid steppe environment, a unique stony plain known as 'coussoul' formed by ancient river deposits.
The primary activities are human-powered outdoor sports suited to the flat terrain. This page aggregates over 400 routes for hiking, cycling, and running. Birdwatching is also a major activity, particularly in the wetland reserves which are crucial migratory hubs for hundreds of bird species, including greater flamingos.
The Réserve Naturelle de Camargue offers over 100 routes for hiking, cycling, and running through its wetland habitats. The reserve features specific walking trails, such as a 0.9-mile (1.5 km) nature trail at the La Capelière visitor center and a 2.8-mile (4.5 km) trail system at Salin de Badon. The 'Digue à la mer' sea wall also provides a long path for walking and cycling along the coast.
