Masbo, Urban beach in Moncofa, Spain

Masbo is a gravel beach in Moncofa, on the Mediterranean coast of the Castellón province, running about 800 metres along the shoreline with a width of roughly 20 metres. It lies directly beside the town, so the promenade and streets lead straight onto the pebbles, and the whole length gives access to the water for swimming and wading.

The beach gained importance in the 1970s when a campsite attracted visitors from around the world, establishing it as a coastal destination. This early growth transformed it into a popular holiday destination in eastern Spain.

The name Masbo refers to a former freshwater channel that fed a lake in the Moncofa area, and locals still use it for the beach. In summer the shore hosts family gatherings and swimming, with the campsite established in the 1970s bringing repeat visitors who mix with residents.

The beach provides public facilities including toilets, showers, a children's playground, sports areas, and parking for more than 100 vehicles. These amenities make it easy to spend a full day by the water.

Masbo takes its name from a water channel that once linked to a former freshwater lake in the Moncofa area, a reminder of how water shaped the local place names. The same name is still used for the beach today.
