The Blue Cave on Biševo island glows an otherworldly blue when sunlight hits the water at the right angle, and it’s usually combined with a stop on the lively island of Hvar in the same day trip from Split.
Full-Day Boat Tour
A full-day boat tour on a larger vessel covers the Blue Cave, Hvar, and often the Blue Lagoon on Budikovac, at a relaxed group pace with more stops.
Small-Group Speedboat Tour
A small-group speedboat tour moves faster between islands, often getting to the Blue Cave earlier in the day when the light effect is strongest and crowds are thinner.
Is the Speedboat Tour Worth It?
Timing matters enormously for the Blue Cave’s light effect, so the speedboat’s earlier arrival is a real advantage; the larger boat tour is a fine, more affordable option if timing is less critical to you.

Practical Tips

- Bring a swimsuit – most tours include swim stops at Hvar or the Blue Lagoon.
FAQ

Final Thoughts
