2/5 - Disappointing
Entering cave was an experience and impact of light on water gave a pleasing blue glow. But boatman's insistence on a tip for "service" which was two laps of a small cave, bad singing and jamming us in the tiny bow of the boat, detracted. Duration in cave was 2mins top and service is already included in the entrance fee. Disappointing that some tourists felt the need to tip heavily, so this will not stop the boatmen getting away with daylight robbery. Inst ead take the 1hr round island boat tour and you will see the blue grotto effect in mini blue grotto plus much more.
