Port de Peníscola (Generalitat Valenciana)

Tucked into the bay beneath Peníscola's dramatic medieval castle, this small marina keeps things simple with around 75 berths and a maximum boat length of 8 metres — so it's best suited to compact vessels. The setting is genuinely special, with the old fortified town rising straight out of the rock above you. It's a great base for exploring the Costa del Azahar by sea, and the historic old town is just a short walk from the dock.
