In April 2018, the Orígens UNESCO Global Geopark,, located in the Catalan Pyrenees, was formally declared a full member of the Global Geoparks Network, and became the second Geopark in Catalonia.

In countries where there are Geoparks, the Global Geoparks Network is represented through national Geopark forums or committees.

The Spanish Geoparks Forum is made up of the 15 existing Geoparks and several individual members of the GGN. Its task is to coordinate the work carried out at a national level related to the Global Network and UNESCO, as well as to ensure that the values of the Geoparks are properly disseminated, to organise joint promotional actions, and to provide appropriate information and advice on new Geopark projects.

The Geoparks that make up the Forum (July 2020) are:

In February 2015, a collaboration and joint promotion agreement was signed with the UNESCO Global Geopark in Tianzhusha (China).

It covers an area of 415 km2 and its highest point, Mount Tianzhu, is 1489.9 m above sea level.

In November 2017, a joint collaboration and promotion agreement was signed with the UNESCO Global Geopark in Yuntaishan (China). It is located in the north of the city of Jiaozuo, in Henan province, northern China. It is a Geoparc located on the southern slope of the Taihangshan Mountains, with a total surface area of 556 km2 and characterised by rift tectonics together with spectacular landscapes formed by hydrodynamic processes, combined with a relict cultural and natural scenario. Mount Yuntai, with an altitude of 1308 m, stands out.
