We went to the Cyclades in early May and swim only once. The water was cold, the beach clubs were shuttered, and some afternoons the wind made us reach for long sleeves. We’d do it again.

Greek Islands in May

Early May avoids crowds but arrives before the beach season starts.

Good news: the crowds were light. In Milos and Paros we could just walk up to the most popular restaurants right at 7:30pm; Santorini was already busy even in May.

If you’re coming for beach clubs, early May isn’t it — they open in June. The beaches are empty, the lounge chairs stacked and unavailable. For swimming and sunbathing, this isn’t shoulder season. It’s still off-season.

Many days topped out in the high 60s, and wind made long sleeves necessary by evening — sometimes by afternoon.

Wind was the wildcard, and locals say that can be true all summer. One afternoon hit 30–40 mph; an hour later it was calm enough for an outdoor dinner.

We swam in the Mediterranean only once, during the Santorini catamaran cruise. The water was bracing. Doable but hardly “relaxing” water temp. Late September is likely a better overall choice — when the water is warmer, but the crowds still thinner.

Choosing Your Islands

3 overnight stops in 10 days was the right number. Ferries eat time: the 30-minute early arrival, the shuttle logistics, and the repacking. Anything more than 3 overnight stops in 10 days (2 nights in Milos, 3 nights in Santorini, 5 nights in Paros) might feel like work rather than travel.

But we managed day visits to Naxos for 6 hours, and Antiparos, Delos and Mykonos for 3 hours each. We only repacked luggage 3 times but still saw several islands, and we were surprised how different neighboring Naxos and Paros felt.

The contrast between islands is sharper than we expected. Milos is sleepy — Pollonia’s entire restaurant row fits into a compact strip. Santorini is the opposite: overrun with tourists, Oia almost entirely depopulated by locals who have been priced out. And yet it’s one of the most remarkable sights we’ve ever seen. Paros sits between them: first-class hotels and restaurants, genuinely busy, but still feels like a place actual Greek people live.

These impressions are May impressions. Our friends who visited Milos in September came back raving about beaches we never saw open.

In early May, the beach isn’t really “ready” yet (and the water is seriously cold), so for us 48 hours in Milos … was plenty, because there’s only so much to see.

Ferries

We flew Athens to Milos at the beginning, and Paros to Athens at the end. We only took three ferries, so consider these field notes, not expertise.

We used Ferryhopper to compare routes, but the fastest option for us was always Seajets. We booked directly through their website a few weeks in advance, and paid the premium for “club” — the Seajets “business class”. It’s less crowded and usually only 10–20% more expensive. They had a platinum class for our long ferry (Santorini to Naxos, 2.5 hours) and that had at-seat drink service which was welcome.

Check into Seajets online between 48 and 2 hours before departure to get a QR code to scan. If you miss the online window, you’ll need to find an in-person desk (usually near but not right at the ferry dock).

Hire a Guide

Hire guides selectively, but hire them.

Our Athens guide at the Acropolis gave us things we couldn’t have found on our own, and helped navigate a museum with a complex story.

Our Naxos guide Alex made a six-hour visit feel complete.

Delos without a guide cost us probably half the experience.

Cars and Taxis

Island by island, the right choice can vary greatly:

• Milos: mandatory, but don’t get the bigger car. Taxis are non-existent.

• Paros: Rent for 2 days to see the interior and the southern beaches, then return it and walk Naoussa for the rest. Taxis are expensive but we just avoided needing them.

• Santorini: skip renting a car, parking and traffic are both difficult.

• Athens: skip it, use Uber. Taxi drivers may not speak English, having Uber handle the destination and payment removes the friction entirely.

Eating Through Greece

The standard of cooking in the islands surpassed expectations, and shaped how we ate by the end of the trip.

When you’re in the islands, the “view” restaurants by the water (Milos, Paros) or on the rim (Santorini) are consistently fish-focused, sometimes with added lamb and beef.

A block or two off the waterfront, you’ll usually find well-seasoned gyros or souvlaki or kebabs at lower prices. Use the view restaurants for fish and scenery; use the back-street spots for speed and value.

Try moussaka. Often. Every restaurant has its own version, and comparing them became a running project. Yemeni in Paros set the bar — see our Paros page for why.

Greek desserts are dangerous. Many restaurants have a dessert menu, and when you decline, they bring a free treat anyway that we consistently failed to resist.

Wines and Wineries

The Cycladic islands are not easy on grapevines. The Meltemi winds strip exposed fruit, rainfall is scarce, and the volcanic soil offers minerals but almost no organic matter. The vines have adapted accordingly — on Santorini, they’re wound into low baskets called kouloura, grapes growing inside the coil, shielded from wind and sun.

What the harsh conditions take away in yield, they add in character. The volcanic soil gives the whites a mineral, almost salty edge that’s hard to find elsewhere. And because the vine-killing phylloxera louse can’t survive in sandy volcanic ground, many Cycladic vines are ungrafted originals — some hundreds of years old, still producing.

The most common cycladic varietal is Assyrtiko. The grape produces bone-dry, high-acid white wines with intense citrus and mineral notes. It is one of the few white grapes that can age for decades. We enjoyed this, but found that its acidity wore on us over 10 days.

Beyond Assyrtiko, two lesser-known whites are worth seeking out. Monemvasia is the richer of the two — rounder, more textured, with a weight that surprised us. Malagousia is brighter and more aromatic, closer to Viognier in style, with a floral intensity that works well on a warm evening. We ended up ordering these more often.

The red wines from the islands … didn’t impress us.

The islands are simply too warm to grow most red grapes. On cooler evenings, Xinomavro from northern Greece was the red to reach for.

Small wineries on several islands turned out to be highlights: Kostankis on Milos, Vassaltis on Santorini, Moraitis on Paros. None felt like a polished tasting room. The pours were unhurried, the conversations personal, and the vineyards were right there — small, windswept, and visibly working for every grape. If you drink wine in the Cyclades, drink it where it’s made.

We skipped the Ouzo entirely, preferring Mastiha as a refreshing, palate-cleansing after-dinner drink.

Early May gave us the Greek islands at a humane volume: easy tables, daylight towns, and long walks without heat. The tradeoff is that the beach culture is still in storage—literally—so plan your days around views, villages, and food, not swimming.
