Ferry tickets and island transfers are in; lunch and towels are not, and much of the day is transit. 4.63 from 226 reviews at €209 per person. In our comparison: #61 of 70 in Day Trips, by rating weighted by review volume (table below). ## Overview Experience the Brightest bioluminescent bay on the World!
