By way of this route, it is possible to see birds from Africa in summer and birds from Central and Northern Europe in winter.

The route runs through various environments, such as reed beds, riverside areas of the rivers known as Riu Bullent and Riu Salinar, rice fields and Mediterranean mountains.

In the Muntanyeta Verda area, a reintroduction project for the osprey within the Valencian Community has been underway since 2019. This means that during the summer months it is possible to observe these specimens.

In the rice fields, the traditional rice cultivation cycle causes the water levels in the fields to vary throughout the year, attracting a large number of birds, mainly of the aquatic kind. Many birds visit the rice fields to feed and even to breed in spring.

In areas where marsh vegetation predominates, such as cane fields, many aquatic birds find shelter in the thickets of the reeds, where there are open water bodies, irrigated by canals and lagoons, locally known as "lluents".

In addition, by walking along the route in silence, the stroll is accompanied by the calls of the swamphen, the dabchick, the water rail, the reed warbler and the moorhen. It is also possible to observe the Valencia toothcarp, an endangered species of fish.

Many of these birds are under threat of extinction and are listed in national and regional catalogues of protected species.

Riu Bullent is a unique river on the Mediterranean coast, with its crystal-clear waters and important environmental aspects. It is the most abundant river in Europe (with the shortest distance) and provides the Marjal area with pure water from the north. It is home to a large number of bioindicator species of wetland quality.

The destruction of wetlands, the use of pesticides, the excessive extraction of water from aquifers, the alteration of riverbanks and riverbeds, as well as the arrival of invasive species, have all caused a situation whereby a lot of aquatic flora and fauna is on the verge of extinction.
