Puerto Tofiño

Puerto Tofiño sits inside Bahía de la Isla Grande on the Columbretes Islands, a volcanic archipelago and marine reserve about 30 miles offshore from Castellón — making it the only port out here and one of the more remote destinations on Spain's Mediterranean coast. The isolation is the whole point, with the surrounding protected waters offering some of the clearest and most biodiverse sea in the western Med. You'll need to plan the trip as a full day out, with departure from Castellón typically around 8:00 and return by early evening.
