Yes, it’s possible. Get the SeaJet ferry from Athens to Mykonos. It should arrive at 9:30am or shortly after. You’ll have to hurry to store you’re luggage at the Sea and Sky travel agency across from the Old Port and then buy tickets for Delos. The last ferry to Delos leaves at 11am or maybe 11:30am. Ferry to Delos is about 30 minutes. Last ferry back is at 3pm which will give you plenty of time before the last ferry of the day to Naxos (at 6:15pm on SeaJet). All the ferries mention here use the Old Port. Don’t book any ferries that use the New Port or you’ll have trouble making the connections.
As soon as I think of travel, it’s not long before my mind drifts to white sand beaches, azure blue water, and palm trees in tropical locales. When most people think of paradise, chances are they’re thinking of tropical islands is far-flung corners of the world. Lounging with a good book, drinking from coconuts, soaking up the rays. Does it get any better than that?
Also, if there are any other suggestions you have in general for Athens and Santorini I would love to hear them. I would like to be able to leave Athens early morning on Day 3 so that we can have almost a full day on our first island. We would like to see as much as we can without feeling like we are running around from island to island the whole time.
Unlike its parched Cycladic neighbours, Andros is refreshingly lush. The ancient Greeks called it Hydroussa ('watery') because of its plentiful waterfalls and springs. Marble lions spout ice-cold mineral water at Sariza and Menites. Streams signposted by pink ribbons of oleander tumble down valleys criss-crossed with stone bridges and footpaths. (Some 170km of hiking trails have been waymarked; find out more at Andros Routes). Falcons and monk seals duck and dive at blissful, blustery beaches including Zorkos, Vitali and Vori.
The mountainous interior, all sleepy stone villages poking out of pine forests, is great for hikes and bikes. (Eco Zante can arrange outdoor activities guided by insiders.) Askos Stone Park is a wildlife sanctuary inhabited by deer, chinchilla, and dozens of other species. After exploring the Venetian castle high above the harbour, treat the kids to thin-crust pizzas (with grown-up toppings like bresaola, aubergine, and gorgonzola) at Alesta on cute St Mark's Square.
Where to stay in Crete: A 300-year-old hamlet surrounded by olive groves, Kapsaliana Village Hotel exudes peaceful authenticity. On a sandy bay just beyond Chania, Ammos Hotel smartly combines Scandi chic with a child-friendly vibe. Blue Palace Resort & Spa beats the (stiff) competition in Elounda with its spiral stone Isola Beach Club, thalassotherapy spa, and boat trips to Spinalonga island, a national monument just across Mirabello Bay.
