41.6 km circular route starting at Oliva Tourist Info and ending at the same location. The route will take us along paths, ravines and tracks to the Marjal Pego-Oliva natural park. Located in a cove between the Mostalla and Segària mountain ranges, it constitutes the southernmost coastal wetland in the Gulf of Valencia. It is a mixed space, built from geomorphological processes and anthropic action not without conflict.

The ecological wealth and the exceptional hydrological system of the marsh have led to greater environmental sensitivity and the declaration of 1,290 hectares as a protected area, both at the regional and European level. Inside the park the route will take us to the bird observatory. We will retrace our tracks to get among the motes of the rice fields and thus reach the Ullal del Bullentó. Here we can supply ourselves with water for the challenge of the route.

We will go through the most beautiful part of the park, the Salinar, the Muntanyeta Verda and the Blau del Calapatar, to return to the behavior of Sant Pere, which regulates the flow of the River Bullent. These are of vital importance for the water regulation of the park.

We will go out along the footbridge to the Font Salada or Ullal del Burro, a source of saline water with healing properties for the skin, where we can refresh ourselves by taking a thermal bath in its waters always at 24º or at the beach bar with a good soft drink.

Little by little we will leave the natural park to reach the coast and cross it from Oliva Nova to Oliva, passing through the camping area, the Dunes of Rabdells, the mouth of the Gallinera river and the Oliva promenade. Once this part of the route is completed and after the yacht club we will arrive at Vall de les Fonts, a track that will bring us back to the beginning of the route.
