Blue Cave Small-Group Boat Tour from Dubrovnik
About this activity
Explore the stunning Blue Cave and hidden grottoes of the Elaphiti Islands on an intimate small-group boat tour from Dubrovnik. This 4-hour adventure combines swimming at pristine Lopud Beach with exploration of three sea caves, designed to minimize crowds while maximizing personal attention and safety.
This is a unique way to experience the magical ambient of Blue cave.
We go only with small groups, so we can approach each guest individually. Our route is carefully planned to avoid crowd and too many visitors.
In this tour you will spend time on sandy Lopud beach Sunj where you will have time to swim before we go to explore caves. Afther that we will take you to visit Three caves on Koločep Island where you can spend time exploring the untouched nature of Elaphiti islands.
The third and most important stop is the magnificent Blue Cave.
Our skipper will briefly describe how to enter the caves and provide all safety advices and help if needed. Your boat is always moored close to you, and you will be supervised by our experienced skipper at every moment.
Entering inside the caves by swimming is most amazing act of this tour. All shades of blue mixed with sun rays, will beat up all your expectations.
This is something you will talk about.

Insider tips
