Greek Island Wanderer — Self-Launched Island Hopper

Land at Athens Airport and take the metro Line 3 (€9, ~40 min) or the X95 express bus (€5.50) to Monastiraki/Syntagma. Check into a hostel or budget hotel around Psyrri or Monastiraki — this is the cheapest central cluster. Spend the evening on foot: Psyrri for souvlaki and ouzo, then wander down to Plaka at the foot of the Acropolis for tavernas and a first glimpse of the lit-up Parthenon. Pick up a 3-day/5-day Athens transport pass if you'll be using buses and trams.

🚌Airport metro Line 3 ~€9 (~£8)

🛏Hostel dorm or budget guesthouse, Psyrri/Monastiraki (£20–30)

• →Psyrri district food walk
• →Plaka tavernas
• →Evening Acropolis viewpoint from Areopagus Hill

Book an Acropolis skip-the-line combo ticket (€30, covers the Acropolis, Ancient Agora, Roman Agora, Kerameikos and more — valid several days). Go early (8am opening) to beat the heat and crowds in summer. Do the circuit yourself: Temple of Athena Nike, the Parthenon, the Erechtheion. Then walk down through Plaka and the whitewashed island-style lanes of Anafiotika, cross the National Gardens, and time your arrival at Syntagma Square for the hourly changing of the guard at the Tomb of the Unknown Soldier. Optional: Acropolis Museum (€15 summer). Consider a small-group walking tour via GetYourGuide (~£25–35) if you want context without a full tour leader.

🚌On foot + metro day ticket ~€4.10

Take metro or bus to Piraeus and catch a morning Blue Star ferry to Syros (~3.5–4 hrs, €40–48 on deck/standard). Note ferry schedules a day ahead — the Cyclades run several boats a day in season but only one or two in shoulder season. Arrive into Ermoupoli, the elegant neoclassical capital, and check into a guesthouse in Ermoupoli or down in Galissas. Afternoon: local bus to Kini and walk the easy coastal path over to Galissas (~4.7 km, ~2 hrs, one steep little climb) with swimming at both ends. Bus back to town.

Morning coastal walk from Galissas toward Vari (~4 km, ~1.5 hrs) with a swim and a taverna lunch, then bus back. In the afternoon climb the 1,000-odd steps (or catch the little bus) up to Ano Syros — the old Catholic hill town with castle gates, the Capuchin church and huge views over the harbour. Stop at a loukoumi (Turkish-delight) workshop in Ermoupoli for a tasting — Syros is famous for it. Evening: aperitivo in Plateia Miaouli, the grand marble main square.

Shortish hop to Paros (roughly 1–2 hrs, €15–25). Base yourself in Parikia for convenience, or Drios on the quiet east coast as the original trip does (buses connect both). Settle in, then take the local bus from Parikia to Drios and walk out to Fonikas and the little Church of Agios Panteleimonas, or continue to Kokkina (Red) Beach — easy 45-minute routes each way. Evening in Parikia's old town lanes behind the port.

Morning bus to Parikia to see Panagia Ekatontapyliani (the Church of 100 Doors, one of Greece's oldest churches, free/€2), the Venetian fortress remnants and the waterfront cemetery, plus the small Archaeological Museum. In the afternoon, book a traditional caique boat trip from Parikia or Drios via GetYourGuide or at the harbour kiosk (~£30–45) with swim stops and lunch — weather dependent, so have a Plan B. Alternative: bus to Naoussa, the postcard fishing village, for wine and jam tastings in the cafes.

Bus up to Lefkes, the handsome marble village in the hills, then walk the old Byzantine road (a paved 1,000-year-old path) downhill through olive groves and terraced fields to Piso Livadi on the coast — about 3–4 km with almost no climbing. Lunch by the harbour, swim at Piso Livadi or continue to Golden Beach (bus) for the best sand on the island. Alternative for foodies: a half-day Greek cooking class in Paros or Naoussa (~£45–60).

Morning ferry Paros to Naxos (30–60 min, €10–15). Drop bags at a guesthouse in Naxos Chora, then do a self-guided orientation of the old town: the Portara (the giant marble gate of the unfinished Temple of Apollo, best at sunset), the Venetian Kastro quarter, and the winding Bourgos lanes. Free walking-tour apps or a printed old-town map at the tourist office work fine here. Evening: Naxos is Greece's cheese-and-potato island — eat well.

🚌Ferry ~€13 (~£11) + buses €2

🛏Guesthouse/studio in Naxos Chora (£20–30)

• →Portara at sunset
• →Kastro and Bourgos old town walk
• →Naxos waterfront

Book a full-day boat trip to Delos and Mykonos either via GetYourGuide/Klook (~£45–55 plus €12 Delos site entry) or at a Naxos harbour agency. On Delos, walk the Terrace of Lions, the 3rd-century BC theatre and the Temple of Apollo, and climb Mount Kynthos (113 m) for the island panorama. Then a couple of hours on Mykonos: windmills, Little Venice, boutique browsing. Boats run in season only and depend on wind — confirm the day before and keep the Bazeos Tower/Halki plan in your pocket as a swap.

🚌Boat trip departing Naxos (included in activity cost)

🛏Guesthouse/studio in Naxos Chora (£20–30)

• →Delos archaeological site
• →Mount Kynthos climb

Take the bus to Tragea/Halki (or Tsikalario) and spend the day in the island's green interior. Visit the 17th-century Bazeos Tower (small entry), then Halki, a lovely Venetian-era village with a square made for morning coffee and a kitron liqueur tasting at the Vallindras distillery. From Kinidaros you can walk to Eggares (~7 km, ~3 hrs, moderate) for the Olive Press Museum and Byzantine churches — or just take the bus to Eggares if it's hot. Back to Chora by late afternoon.

🚌Local buses ~€6

• →Bazeos Tower
• →Halki village and Vallindras distillery

Ferry Naxos to Santorini (1–2 hrs, €25–35; the high-speed option is quicker and bumpier). Stay in Karterados or Fira rather than Oia — beds are half the price and buses connect everything. In the afternoon, book a Santo Wines or Estate Argyros tasting directly (~€25–35 for a flight with caldera views) — book ahead in high season, or join a small-group winery tour via GetYourGuide (~£45). Sunset from Pyrgos or a caldera-view terrace if you want to avoid the Oia crush.

🚌Ferry ~€30 (~£26) + local buses €4

🛏Budget guesthouse/hostel in Karterados or Fira (£30–45)

• →Ferry crossing
• →Santo Wines or Estate Argyros tasting
• →Caldera sunset

Book a caldera volcano boat trip at the old port below Fira (walk down the donkey steps or take the cable car, €6) — half-day or full-day options run ~£25–40, plus €5 volcano entry. Climb to the crater rim (~30 min each way, steep and rocky — wear real shoes), swim in the warm springs, then stop on Thirassia for lunch and a walk through the vineyards and hill village. Alternative: ancient Akrotiri with a small-group guide (~£35) and the Prehistoric Museum of Thira in Fira.

🚌Cable car €6 + buses €4

🛏Budget guesthouse/hostel in Karterados or Fira (£30–45)

• →Volcano crater climb
• →Hot springs swim
• →Thirassia island stop
• →Optional Akrotiri site

The headline walk: Fira to Oia along the caldera rim, 10 km and 3–4 hours with constant ups and downs and zero shade. Start early (7–8am) with water and snacks; coffee at the halfway point in Imerovigli or a taverna in Oia at the end. Explore Oia's cave houses, captain's houses and the castle ruin, then either walk back or take the bus (€2) to Fira. Stay for the Oia sunset only if you enjoy crowds — the Fira or Imerovigli sunset is just as good and far calmer. Reward yourself with a long dinner in Fira.

🚌Local buses ~€4

🛏Budget guesthouse/hostel in Karterados or Fira (£30–45)

• →Fira–Oia caldera hike (~10 km)
• →Imerovigli

Breakfast, then local bus or short taxi to Santorini Airport (JTR). If you need to get back to Athens instead of flying home from Santorini, the fastest option is a 45-minute flight (book early, ~£40–90), or a slow overnight ferry back to Piraeus (~8 hrs). Build in a buffer day if you're catching a long-haul connection.

🚌Local bus to JTR ~€2, or flight/ferry onward
