The marina is named after the 'les fonts' (the fountains), referring to the underground freshwater springs that emerge within the port's perimeter.
The freshwater discharge creates a visible mixing zone where water temperatures and salinity levels fluctuate compared to the open Mediterranean.
It is situated at the edge of the Sierra de Irta, one of the last undeveloped stretches of coastline in the Valencian Community.
The port acts as a primary embarkation point for dive trips to the Columbretes Islands volcanic archipelago.
The unique water chemistry in the harbor area supports specific species of aquatic flora and fauna not found in typical high-salinity ports.
Port Esportiu de les Fonts is a distinct marina located in Alcossebre, known for the unique natural freshwater springs that bubble up directly into the seawater within the basin. It features approximately 300 moorings for vessels up to 15 meters in length. The marina is integrated into the Las Fuentes beach area, characterized by its fine sand and proximity to the Sierra de Irta Natural Park. Unlike traditional harbors, the influx of freshwater affects the local marine biodiversity, creating a unique brackish environment. The facility provides standard nautical services including water, electricity, and 24-hour surveillance. It serves as a gateway for coastal navigation toward the Columbretes Islands. The surrounding promenade offers immediate access to various dining and retail establishments serving the Alcossebre tourist district.
From the breakwater looking back toward the coastline with the Sierra de Irta in the background.
Visit during low tide to better observe the freshwater upwellings near the dock walls.
Check the local wind forecast before planning boat excursions, as the coast here is susceptible to sudden changes.
Combine your visit with a hike on the nearby coastal trails leading into the Sierra de Irta Natural Park.
Do not attempt to swim inside the designated mooring berths due to boat traffic and submerged chains.
The port remains operational year-round, though visitor boat services are significantly reduced during winter months.
Maintain appropriate footwear on docks; refrain from swimming within the active mooring zones.
