Dates are flexible. This day-by-day plan is provisional until you choose exact travel dates.
From BWI, expect a flight to Athens International Airport (ATH) with at least connection; the journey usually takes about 13–18 hours, depending on the connection. For three travelers, allow extra time for immigration and baggage before heading into town. With luggage, a prebooked transfer or official airport taxi is the easiest no-car option: the city-center flat fare is generally about €40 by day or €55 overnight (roughly $45–$60), for the whole taxi. The Metro Line 3 to Syntagma takes about 40 minutes and costs around €9 per adult; confirm current fares and any youth discounts before traveling. July round-trip airfare from BWI for three can vary widely, so check prices early.
After checking in and resting, stroll through Plaka for about an hour; its lanes and shady corners make a forgiving introduction after a long flight. Then climb gently into Anafiotika, the tiny whitewashed hillside quarter above Plaka. Give yourself around 45 minutes, take the steps slowly, and keep voices low—people live in these homes. Wear comfortable shoes, as the lanes are uneven and can be slippery.
Finish at Kostas Souvlaki, near Monastiraki, for a quick, inexpensive first taste of Athens: budget about $8–$15 per person, or roughly $25–$45 for your family, depending on what you order. It’s a short walk downhill from Anafiotika; check its current hours before setting out, since small shops may keep limited schedules and can sell out. Keep this first day flexible—if your flight arrives late, save the stroll for another time rather than rushing through it.
Start at the Acropolis of Athens as close to opening as you can manage; July sun gets fierce on the exposed rock, and the paths are much more comfortable before midmorning. Allow 2–3 hours for the Parthenon, Erechtheion, and other monuments. Buy timed-entry tickets in advance and check the official site shortly before your visit, since entry slots, hours, and prices can change. Budget roughly $30–$40 per adult for admission; children and teens may qualify for free or reduced entry, so bring ID and check the current rules. Wear grippy shoes, carry water, and expect some uneven stone underfoot.
Walk downhill to the Acropolis Museum in Makrygianni—about 10 minutes from the Acropolis entrance—and spend 1½–2 hours among the sculptures and finds from the site. It’s a welcome air-conditioned pause; check the museum’s current hours before setting out, as closing times and weekly schedules can vary. Admission is about $20–$25 per adult, with possible concessions for younger visitors. For lunch, Dionysos Zonar’s is nearby, with a terrace and a classic Greek menu; set aside about 1–1½ hours and $20–$35 per person. For three, that’s roughly $60–$105, before drinks or dessert.
From the restaurant, take a taxi or walk roughly 25–30 minutes—mostly downhill, but hot in July—to the Ancient Agora of Athens in Monastiraki. Give yourself about 1½ hours to wander the old civic center and see the remarkably intact Temple of Hephaestus. The archaeological site generally closes earlier than many city sights, so check its day’s hours and aim to arrive with plenty of time; admission is roughly $10–$20 per adult, depending on the current ticket rules. If the heat catches up with you, take a shaded break and refill water before exploring.
Start at Syntagma Square while it’s still relatively cool. Take the metro to Syntagma station or walk from central Athens hotels; the square is right outside Parliament. Watch the Evzones guards at the Tomb of the Unknown Soldier—there’s a brief changing ceremony every hour, though the larger Sunday ceremony is on a different schedule. Allow 30–45 minutes, then cross into the National Garden for a shaded, unhurried walk. It’s free, and a good place to pause with a cold drink before the heat builds; paths and gates generally follow daylight hours, so check locally if you’re visiting early or late.
Walk about 20 minutes through the center toward Panathenaic Stadium, or take a taxi if the July sun is punishing. The all-marble stadium is where the first modern Olympic Games were held; allow about an hour to explore, and expect admission to be roughly $12–15 per adult. Check the current ticket rules for your teen, as reduced or free admission may depend on age and proof of eligibility. Afterward, take a taxi or public transit to Plaka for lunch at Kafeneio on Epicharmou Street. Settle in for traditional Greek dishes and a relaxed meal; budget around $18–30 per person, or roughly $55–90 for three, before drinks.
Keep the rest of the day flexible rather than adding another major stop: linger over lunch, browse Plaka’s lanes, or head back to your hotel for a break during the hottest hours. For the day’s visits and local transit, budget approximately $80–120 for three, including the stadium, meal, and a few metro or bus fares; taxis would add to that.
Allow for the ferry crossing and port transfers before planning anything in town; sailings take roughly 2.5–5 hours, and July services can run late or change with the weather. Once you arrive, collect your bags and check in—then keep the first outing light. If you’re staying outside Chora, use a taxi or the local bus rather than renting a car; taxis are limited, so confirm your pickup or transfer in advance.
Get your bearings with an easy 45-minute stroll around Mykonos Old Port, where fishing boats and ferries share the waterfront. From there, wander into Matogianni Street and its narrow side lanes for about an hour of browsing; shops often open later in the morning and stay open into the evening in summer. The whitewashed lanes are easy to lose yourself in, so save a map pin for your hotel and wear shoes with grip—the polished stone can be slippery.
Book a table at M-eating for a relaxed Greek dinner in Chora; budget about $30–$50 per person, or $90–$150 for three, before drinks. Allow around 1.5 hours, then take an unhurried walk through the lanes back to your accommodation. If you’re tired from the travel day, make this your only evening plan.
Head to Platis Gialos Beach early, before the sun and crowds peak. From Mykonos Town, take the southbound bus from the Fabrika terminal; the ride is about 15–20 minutes, and buses run more often in summer, though schedules can shift. Settle in for a couple of hours of swimming and shade. The beach has sunbeds, showers, and places to grab a drink; loungers can be pricey in July, so ask the rental cost before sitting down or bring towels for the public sand.
Walk about 15–20 minutes along the coastal path to Paraga Beach—wear sandals, as parts of the route are uneven. Take a swim, then have lunch by the water; plan roughly $25–60 per person at a beach-club restaurant, with drinks and loungers adding to the bill. Continue on foot to Paradise Beach in about 20–30 minutes, or take a short taxi if the heat is wearing you down. Spend 1.5–2 hours here: enjoy another swim or stroll the shoreline, and choose a quieter stretch if the beach-club music feels lively.
Return to Mykonos Town waterfront by bus from the south-coast stops or taxi; allow extra time in July, when vehicles and roads get busy. Wander the harborfront, then find dinner around the waterfront or in the lanes just inland—budget about $25–45 per person for a meal. Buses back toward the south-coast beaches generally run into the evening in high season, but check the day’s timetable before settling in; taxis are limited, so don’t count on finding one instantly.
Start at Mykonos Windmills before the midday heat and photo crowds; allow about 45 minutes, and bring water because there’s little shade. From central Chora, they’re an easy walk. Continue on foot to Little Venice—around 5–10 minutes away—for a waterfront wander and time to admire the sea-facing houses. The two stops are close together, so there’s no need to rush between them.
Take a taxi from Chora to Fokos Taverna, roughly 25–35 minutes depending on traffic. It’s a good place for a leisurely meal by the quieter north-coast beach; budget about $25–$40 per person (roughly $75–$120 for three, before drinks). Taxis are limited in this part of the island, so arrange your return pickup with the driver or taverna before settling in. Confirm the fare and whether the restaurant is accepting cards when you call.
Return to Chora for the Archaeological Museum of Mykonos and allow about an hour for finds from Mykonos and nearby Delos. Seasonal hours and closing days can change, so check the museum’s current listing before making the trip; if it’s open, confirm its last-entry time as well. Allow roughly $5–$15 total for the taxi round trip per person, depending on the arrangement, and keep the rest of the afternoon flexible.
After the morning ferry reaches Athinios Port, allow time for the busy disembarkation and transfer up to Fira; a prebooked transfer is handy in July, when taxis can be scarce and port traffic backs up. Ferry tickets are roughly $75–$110 per person (about $225–$330 for three), before transfers. Once you’ve dropped your bags, take an easy walk along Fira’s caldera rim for about an hour. The views are superb, but the paths are exposed, so bring water and a hat.
Visit the Museum of Prehistoric Thera, right in Fira, for a focused look at artifacts from ancient Akrotiri; allow about an hour. Summer hours and weekly closing days can change, so check the museum’s current schedule before setting out. Admission is typically around €6–€12 per adult; confirm the teen rate and any concessions on the official listing. Then leave time to rest at your lodging or wander Fira’s lanes before dinner.
Book Argo Restaurant for dinner and request a caldera-view table when reserving; sunset seating is popular in July. Plan on about 1½ hours and $30–$50 per person, or roughly $90–$150 for the three of you before drinks and extras. Arriving a little before your reservation gives you time to settle in without rushing.
Take a KTEL bus from Fira to Perissa—usually about 30–40 minutes, with more frequent service in summer, but check the day’s timetable before setting out. Get there early for a few hours on the black-sand beach, when it’s cooler and easier to find a spot. The beach itself is free; sunbeds and umbrellas are extra, with prices varying by section. Bring water, sandals for the hot sand, and sun protection.
From Perissa, continue to Ancient Thera, the hilltop ruins above the beach. The climb is steep, exposed, and tiring in July; don’t attempt it in the strongest midday heat. A safer no-driving plan is to take a taxi to the site access from the Kamari side, then walk around the ruins, allowing 1.5–2 hours. Check the current opening hours and access arrangements before you go, as they can change. Entry is typically around $10–$15 per adult; confirm the latest fee and any youth discount.
Arrange a taxi or prebooked transfer from the Pyrgos area to Santo Wines; reserve ahead for a winery visit with caldera views. Tastings are roughly $20–$45 per adult—check age rules and tasting options for your teen. Then take a taxi or arrange a transfer to Metaxi Mas in Exo Gonia for dinner; book a table, especially in July. Expect about $25–$40 per person for dinner, before drinks. For three travelers, budget roughly $120–$220 for Ancient Thera entry, a winery visit, and dinner, plus beach rentals and taxis; agree on transfer costs when booking.
Take a KTEL bus toward Akrotiri early, checking the day’s summer timetable before you leave; buses can be busy, and a taxi or prebooked transfer is the more reliable option if connections don’t line up. Spend 1.5–2 hours at Akrotiri Archaeological Site, where a roof shelters the excavated Bronze Age streets and buildings from the July sun. Admission is usually around $15–$20 per adult; confirm seasonal hours and any weekly closing day before you go. Continue to Red Beach for the dramatic volcanic cliffs and shoreline. Allow 45–60 minutes, but check local access conditions: rockfall risk can close the path, so admire it from a safe viewpoint if access is restricted rather than attempting a descent.
From Akrotiri, continue by bus or taxi to Pyrgos—allow roughly 20–30 minutes by road, longer if you’re connecting by bus. Wander the whitewashed lanes uphill toward the castle for wide island views, then pause for a shaded drink or a leisurely lunch; budget about $20–$35 per person for a sit-down meal. Give the village around 1.5 hours, and wear shoes with grip for the steep, uneven lanes.
Head to Oia well before sunset; a taxi or prearranged transfer saves time, while buses involve a change and can be packed. Leave at least 2–3 hours to explore the lanes and find a viewpoint, and expect dense crowds near sunset. For the return, agree on a taxi pickup in advance or check the latest bus departures—queues can be long, and there’s no guarantee of finding a taxi on the spot. For three travelers, set aside roughly $15–$30 total for bus fares across the day, or more for taxis; bring water and keep some flexibility in the schedule.
Have a relaxed final breakfast in Fira near your lodging; budget about $12–$25 per person (roughly $36–$75 for three) and give yourselves an hour. Then take a 45-minute last stroll along the Fira caldera promenade before returning for your bags. Keep the walk close to your lodging and leave a little buffer—July heat and busy lanes can make even a short outing feel slower.
Take a taxi or prebooked transfer from Fira to Santorini Airport in the Kamari area. The drive is often around 10–15 minutes, but allow 30–45 minutes in July for traffic and drop-off queues; aim to reach the airport about two hours before a domestic flight, or follow your airline’s longer check-in guidance if your itinerary requires it. Fly from Santorini to Athens, then connect onward to BWI. Expect roughly 15–22 hours door to door, depending on connections. If the Athens–BWI flight is on a separate ticket, leave a generous connection or consider an overnight in Athens, since a delay on the island flight could put the onward journey at risk.
For two adults and one teen, a very rough July 2027 estimate for the full trip is $9,000–$17,000 total, including round-trip flights from BWI, nine nights’ lodging, meals, ferries, local transport, and sightseeing. Actual costs will depend most on airfare, room arrangements, and how early you book.
