You get the boat ride from the Old Port to Delos and back. That is it. There is not much to it. The boat is comfortable and spacious. You can stay outside or inside. There is a bar with snacks and drinks. They only take cash though, so keep that in mind. When arriving at Delos you will have to purchase the ticket to visit. It is 8EUR. There will be a big line (all the people that came with you on the boat), so I suggest you purchase the tickets to visit the site online in advance. No food and drinks are provided on the island, so get yourself some water before leaving the boat. Delos is great. You can really walk through the remains of a civilization, the site is well marked, and there are plenty of ruins in reasonably good condition. If you have one day to spare when visiting Mykonos, do not miss it.

Best to book in advance if not doing a tour guide as it gets very busy. We visited without a guide but overheard some of the commentary when walking around so if you are interested in the details suggest doing guided tour. Food and drinks available on the boat, great value. Its very hot so you need drinks and snacks for the island. Would highly recommend.

Transfert à partir de Mykonos sur un petit ferry - le kiosque pour échanger la réservation est situé prés du quai d'embarquement donc facile à trouver . trajet assez court et agréable - le bateau dispose d un pont supérieur pour profiter de la vue . par contre l'attente au bureau de vente des tickets pouyr entrer sur le site Delos peut être longue si affluence . A faire absolument si vous aimez l'histoire ancienne .
