Idyllic Aegean: Athens & Island-Hopping Self-Launched

Land at Athens Airport and take the metro Line 3 (or the X95 express bus) into the centre for around £9 — about 45 minutes to Syntagma/Monastiraki. Check into a hostel or budget hotel in Plaka, Monastiraki or Koukaki, then wander the Plaka lanes at dusk, grab a gyros or souvlaki dinner (£5-7) and get an early night. If you're arriving late, buy a 5-day Athens transport pass tomorrow instead of single tickets.

🚌Athens metro Line 3 from airport, ~£9

🛏Hostel dorm or budget guesthouse in Plaka/Monastiraki (£20-30/night)

• →Metro from airport to city centre
• →Evening walk in Plaka
• →Cheap souvlaki dinner

Buy a combined Acropolis ticket (around £26 in high season, book on the official hhticket.gr site or GetYourGuide to skip the ticket queue) and go early — gates open at 8am and it's far cooler and quieter. Walk down to the Ancient Agora, Temple of Zeus and Hadrian's Arch, then do a self-guided loop past Syntagma Square and the Panathenaic Stadium (entry ~£5, or view from outside). Skip the organised orientation drive — the metro and a 24-hour/5-day transport ticket cover everything.

Morning high-speed ferry from Piraeus (Rafina also works) to Mykonos — around 2h45-3h30, roughly £40-55 booked in advance on Ferryhopper or directly with Seajets/Blue Star. Check into a guesthouse in Mykonos Town (Chora) or a camping/hostel option like Paraga or Paradise for cheaper beds; Mykonos Town is pricey in July-August. Afternoon: walk the windmills at Kato Mili, the Little Venice waterfront for sunset, and the narrow backstreets. Eat at a taverna slightly inland rather than on the seafront.

🚌High-speed ferry ~£40-55

🛏Mykonos Town guesthouse or hostel/campsite (£30-45/night in summer)

• →High-speed ferry Piraeus–Mykonos
• →Mykonos windmills
• →Little Venice sunset

Morning swim at Elia, Agios Sostis or Paradise beach — take the local KTEL bus (£2-3) rather than a taxi. Lunch cheaply at a beach canteen. Late afternoon high-speed ferry Mykonos–Santorini (~2h, £45-60), arriving in time for a Fira sunset. Stay in Fira or Karterados (much cheaper than Oia) in a guesthouse or hostel. Note: Santorini beds book out months ahead in summer — reserve early.

🚌Local bus £2-3; ferry Mykonos–Santorini ~£45-60

🛏Fira or Karterados guesthouse/hostel (£30-50/night)

• →Beach morning on Mykonos
• →High-speed ferry to Santorini

Do the famous Fira-to-Oia caldera rim hike (9-10km, 3-4 hours, free) early to beat the heat — sturdy shoes recommended, carry 2L of water. End in Oia for the castle viewpoint, then take the local bus back to Fira (£2). If you want a boat day, a caldera catamaran cruise with lunch is bookable on GetYourGuide from around £90-110 — optional and easily skipped. Sunset dinner in Karterados or Fira rather than Oia to save money.

🚌Local KTEL bus £2-3

🛏Fira or Karterados guesthouse/hostel (£30-50/night)

• →Fira–Oia caldera hike

Morning fast ferry Santorini–Heraklion (~2h, £40-55). Drop bags at a hostel near the port or in the old town, then take local bus #2 to the Minoan Palace of Knossos (entry ~£17, bus ~£2 each way) — go early or late afternoon to dodge the worst heat and the tour crowds. Back in town, see the Heraklion Archaeological Museum (£12, worth it), the Venetian harbour and Koules Fortress, and eat at a meze taverna in the old town.

🚌Fast ferry ~£40-55; local bus to Knossos ~£4 return

🛏Heraklion hostel or budget hotel (£20-30/night)

Day trip east by KTEL intercity bus to Agios Nikolaos (£6-8 each way, ~1h15) — a pretty harbour town with the little Lake Voulismeni and a jump-off point for the Bay of Mirabello. Swim at a nearby beach (Almyros or Kitroplatia), have a long lunch, and return to Heraklion in the evening. Alternatively hire a scooter or join a small-group boat trip if you want more of the coast. Early night — tomorrow is a long ferry day.

Long ferry day: Heraklion–Rhodes fast ferry is roughly 4-5 hours (£40-55); book early. Arrive, settle into a guesthouse inside or just outside Rhodes Old Town walls, then explore the medieval Old Town, Street of the Knights and Mandraki harbour on foot — it's all free. If time allows, take a local bus down to Lindos (£5-6, ~1h) for the clifftop Acropolis (entry ~£10) and the bay, or save Lindos for a morning start tomorrow.

🚌Fast ferry ~£40-55; local bus to Lindos ~£10 return if used

🛏Rhodes Old Town guesthouse (£25-35/night)

• →Ferry Heraklion–Rhodes
• →Rhodes Old Town and Street of the Knights

Two routes depending on your taste. Simplest: fly Rhodes–Athens with Aegean/Sky Express (often £40-70 if booked ahead, 1 hour) and spend the afternoon in Athens. Longer and slower-travel: ferry Rhodes–Milos via Santorini is a full-day slog (8-10h) and only worth it if you're determined to see Plaka, Sarakiniko's white rock moonscape and the sea caves. Milos has cheap guesthouses in Adamas and excellent free swimming — Sarakiniko and Firiplaka. Either way, keep the evening cheap with a supermarket picnic.

🚌Rhodes–Athens flight ~£40-70 or ferry ~£50-70

🛏Athens hostel (£20-30) or Milos guesthouse in Adamas (£30-40)

• →Flight Rhodes–Athens or long ferry to Milos
• →Sarakiniko and Plaka (if Milos)
• →Evening stroll in Plaka/Monastiraki (if Athens)

If you're Athens-based, this is the best-value replacement for the cruise's Kusadasi port call: fly or ferry to Samos and cross to Kusadasi, or — easier from Athens — take a short flight to Izmir (frequent, ~£35-60) and the local train/bus to Selçuk (£2). Base in Selçuk: see Ephesus (entry ~£22 with Terrace Houses extra, or a GetYourGuide guided entry ~£35) including the Library of Celsus, plus the Basilica of St John and Temple of Artemis (free/cheap). Kusadasi's Grand Bazaar and promenade are a short dolmuş ride away. If you'd rather not leave Greece, spend the day on an Athens day trip to Cape Sounion (£7 bus, £10 temple entry).

🚌Flight Athens–Izmir ~£35-60 + local train/bus ~£4

🛏Selçuk pension (£20-30) or Athens hostel (£20-30)

• →Ephesus archaeological site & Library of Celsus
• →Basilica of St John and Temple of Artemis
• →Selçuk town and Kusadasi promenade
• →Alternative: Cape Sounion day trip from Athens

Travel back to Athens (flight or overnight ferry if coming from Turkey/the islands), then head to the airport by metro (£9). If you have time before your flight, do a last walk through the Monastiraki flea market, pick up a cheap lunch, and double-check ferry/flight times — Aegean weather in July-August can occasionally delay ferries, so leave a buffer day if you're on a tight international connection.

🚌Metro to airport ~£9; inter-island/flight return as per route

🛏None (departure day) — or one extra Athens hostel night if needed (£20-30)

• →Return travel to Athens
• →Monastiraki flea market
• →Metro to airport
