Photos of the Greek islands, here Santorini - Cruise boats photos in Greece

But let's return to the volcano...

Several companies offer tours that can last from 3 hours to the entire day (Rates starting from 8 euros for 3 hours).

Flat-bottomed shuttle boats or schooners will land you directly on the black rocks of Nea Kameni.

The companies rarely leave you more than 1H30 on Nea Kameni... because after... "the boat,... it leaves"!
