Costa Esuri Golf Club H2O's Second Nine forms part of a 27-hole facility located in Ayamonte, on Spain's southwestern coast near the Portuguese border. The complex sits in the broader Costa de la Luz region, where golf development expanded during the late 1990s and early 2000s to serve both residential communities and visiting golfers drawn to southern Iberia's mild climate and proximity to the Algarve. The Second Nine shares the property's characteristic flat to gently rolling terrain typical of this coastal plain. Water features figure prominently in the routing—reflected in the H2O designation—with lakes and canals influencing strategy on several holes. The layout incorporates wide fairways and generous landing areas, though approach shots often require precision given the water hazards and bunkering around greens. Native vegetation and stands of Mediterranean pines frame many holes, providing definition and some wind protection. The course serves a mixed clientele of resort guests, local members, and golfers traveling between Spain and Portugal along the A-49 corridor. The facility includes practice areas and clubhouse amenities typical of Spanish resort golf complexes. Playing conditions benefit from the region's abundant sunshine and relatively dry summers, though afternoon winds off the Atlantic can influence club selection and shot-making, particularly during spring and autumn months.
