Costa Esuri Golf Club sits on the eastern edge of Ayamonte in Andalucía, near the mouth of the Guadiana River that forms the border between Spain and Portugal. The course occupies low-lying terrain characteristic of this coastal region, where the landscape transitions from tidal marshlands to gently rolling ground just inland from the Atlantic. The setting offers views across the river toward the Portuguese Algarve and the town of Vila Real de Santo António. The course was designed to accommodate residential development common to Spanish coastal golf properties built during the early 2000s construction boom. The routing works through relatively flat terrain with water features—both natural drainage channels and constructed lakes—playing a significant role in the layout. The name "H2O" reflects this emphasis on water hazards throughout the design. Fairways are typically bordered by Mediterranean vegetation including umbrella pines and palms, providing definition and some wind protection in an otherwise exposed setting. Ayamonte itself serves as a border crossing point and has historically been a fishing and maritime town. The golf course caters primarily to resort visitors and expatriate residents drawn to the lower Guadiana region for its climate and proximity to both Spanish and Portuguese amenities. The club operates as part of a larger residential and hospitality complex typical of Andalusian coastal developments from its era.
