Rhos Llawr Cwrt is a National Nature Reserve situated in the base of the Clettwr valley, some 10 kilometres from the Ceredigion coast, between Ffostrasol and Talgarreg.


Glaciers have scraped and shaped this landscape and evidence of the last Ice Age can be seen everywhere. The most striking of these are the remains of the pingos found on the reserve, landforms which were once small hills but whose summits collapsed when the ice which formed them melted.

The site is an example of post-industrial rhos pasture and carries international importance because it holds one of the best populations of the marsh fritillary butterfly in Wales. At peak times, thousands of butterflies can be seen flying around parts of the site.

This site is used by the Conervation Management System Consortium as a model for teaching conservation management and by Resilience Wales as an introduction the cultural ecology of place and the logic of making community action plans for boosting pride of place.


It has an automatic weather station, one of several set up throughout Wales by Natural Resources Wales.
