Llamas Park, Urban park in Santander, Spain

Llamas Park is an urban green space in Santander featuring a central lagoon surrounded by wooden walkways and cycling paths. The grounds include playgrounds, cafes, and an amphitheater for public events.

Until the early 20th century the vaguada held one of Santander's two main tidal inlets, with coastal dunes and a north-facing slope used for vineyards. Urban growth around the Second Beach of El Sardinero buried the inlet's outlet, cutting off the tides. The wetland was later filled with rubble and untreated wastewater until the city acquired the land and opened the first park phase on 11 May 2007.

The park showcases plants from different climate zones, drawing visitors who want to experience nature within the city. More than half of the trees are native to the region, creating a familiar green setting.

The park has three parking areas and offers about 2.5 kilometers of bicycle paths for easy movement. Drinking fountains and several cafes are distributed throughout, so visitors can easily find water and refreshments.

Parts of the stone blocks of the old Muelle de Naos, a 15th-century quay of Santander's port, were moved into the park after being rediscovered during works on the underground car park beneath Plaza de Alfonso XIII.
