Can anyone help, I am going to Thassos in July, I would like to have a trip out on a Cruiser or 
yacht, Can anyone recommend any reputable sailing people who is based in Thassos Town.
Hey Johnny!
There are several cruiser/yachting companies based in Thassos Town and you’ll find them either at the marina or the old port.
I personally haven’t indulged myself with such an amazing excursion so I can’t give you any personal recommendations but I believe that any that you choose will give you a great experience sailing or cruising around beautiful Thassos.
Sorry for the vague answer, I promise if I try one out myself I will come back here and let you know how it was!
