Sperlonga: Boat Cruise to the Blue Grotto with Swimming offers a wonderful way to experience Lazio’s rugged coastlines and tucked-away caves, all from the comfort of a boat. For about $43, you get a 1.5-hour guided trip that takes you along Sperlonga’s scenic shoreline, with stops at notable sites like the Grotta di Tiberio, natural limestone caves, and the famous Blue Grotto. Led by friendly guides, this tour promises both natural beauty and a touch of history — perfect for travelers looking for a balanced mix of scenery, culture, and fun in the sun.
What we love most about this experience is how it combines stunning coastal vistas with accessible snorkeling and swimming spots that are usually off-limits from land. The chance to float inside the Blue Grotto, with its brilliant blue waters, is unforgettable. We also appreciate how the guide’s storytelling enhances the trip, revealing tales about the Roman emperor Tiberius and the medieval towers that still punctuate the coastline.
A possible consideration is that the weather greatly influences the trip; because it’s a sea-based activity, rougher conditions could lead to cancellations or a less comfortable experience. Planning this tour for the morning can help ensure calmer waters and better visibility inside caves.
