Museos flotantes Delfín S-61 y Albatros III

A genuinely cool stop in Torrevieja where you can explore the S-61 Delfín, Spain's first naval vessel turned floating museum, moored alongside the historic Albatros III patrol boat. The submarine was donated to the city that awarded it its battle ensign back in 1971, which makes this feel like a proper local story rather than a tourist gimmick. Worth knowing: kids under 110 cm aren't allowed on board, so plan accordingly.
