Cefa Natural Park, Protected natural area at western limit of Bihor County, Romania.

Cefa Natural Park covers 5,002 ha of swamps, canals, floodplains, the Rădvani Forest and pastures on the western edge of Bihor County, at the Hungarian border. It was established by Government Decision 1217 of 2 December 2010 and overlaps the Cefa site of community importance and the Pescăria Cefa–Pădurea Rădvani bird protection area.

The park received official protection status through government decision in 2010 to safeguard regional biodiversity. This designation recognized the importance of the wetlands as a habitat for rare species in the area.

The park lies on the Pannonian–Bulgarian migration corridor, one of Europe's main bird migration routes, and its marshes, canals and floodplains are recognised as a wetland of international importance for waterfowl. The Rădvani Forest, included in the park, holds a heronry where grey herons and little egrets nest.

Access comes through National Road DN79 connecting the two main towns, then follow county road DJ797 to reach the park entrance. The best time to visit is during bird migration periods when the largest variety of species is present in the area.

The park lies on the Pannonian–Bulgarian migration corridor, one of Europe's main bird migration routes. Among the protected birds recorded here is the eastern imperial eagle (Aquila heliaca), listed in Annex I of the EU Birds Directive. The Rădvani Forest colony within the park is a nesting site for grey heron and little egret.
