Tremedales de Orihuela, Protected wetland site in Sierra de Albarracín, Spain

Tremedales de Orihuela is a protected wetland reserve in the Sierra de Albarracín featuring peat bogs and marshy meadows. The landscape includes flowing streams and natural springs that support specialized plant and animal life adapted to wet conditions.

The Tremedales de Orihuela are one of four Aragonese wetlands listed under the Ramsar Convention, alongside the Laguna de Gallocanta, the Saladas de Chiprana and the Saladas de Sástago-Bujaraloz. The site covers 1,844 hectares, of which only 5 hectares hold the more than 1,000 small peat bogs. It also forms part of the Natura 2000 network as a Site of Community Importance (code ES2420141) and lies within the Montes Universales hunting reserve.

The local community refers to these wetlands as 'gotiales', reflecting the traditional nomenclature developed through generations of inhabitants in the region.

The reserve can be accessed through marked trails beginning from Orihuela del Tremedal in the surrounding area. Most paths cross open landscape, so appropriate clothing and sun protection are advisable depending on the season.

The site's most striking feature is its setting: peat bogs in a Mediterranean biogeographic region, which sets them apart from the peatlands of the rest of Europe. The surrounding Sierra del Tremedal also holds stone rivers of fractured blocks up to 2.6 km long and 250 m wide, among the longest in the world.
