Santorini Excursion - Nea Kameni

We're thinking of doing a ship excursion in Santorini to avoid the pileup at the tender dock. There is one that offers a boat trip to Nea Kameni and a 40 minute hike up the mountain.

Has anyone done this? Sounds like it smells terrible (sulphur odor). How's the climb?

Hello! Did you end up doing this? If so did you enjoy it? We are thinking about doing this as well on our upcoming cruise.
