Marina Empuriabrava

Marina Empuriabrava is genuinely hard to beat — this is Europe's largest residential marina, with 5,000 moorings and 23 km of navigable canals threading through a whole waterfront town right on the Costa Brava. You can tie up and walk straight into restaurants, shops, and villas, or head out to explore the nearby Greek ruins at Empúries. There's even an aerodrome on-site if you fancy arriving by air.
