Santorini Hidden Gems: 9 Unusual Things
Everyone already knows Oia’s blue domes and the sunset crowd standing on the castle wall. What most visitors never learn is that Santorini is officially Thira, a volcanic caldera rim rather than a beach island, and that the more interesting version of the trip happens away from that one photo: a former capital nobody stops at, an island across the water almost nobody crosses to, and a clifftop ruin most rental-car itineraries skip entirely. Nine unusual things below, plus where they fit against the well-known list. Big ferries land at Athinios, a working port run by the Municipal Port Fund of Thira , a steep switchback below the caldera with no footpath, so budget the transfer time regardless of which of these you add.
| What | Answer |
|---|---|
| Days needed | 3 minimum for Fira, Oia, Akrotiri and one beach; 5-7 to add Thirassia, Ancient Thera and wine country |
| Best months | May and October; June-September is peak heat, peak price and peak crowd |
| Daily budget | EUR 70-150 based in Kamari or Perissa; EUR 300-1,000+ for a caldera-view night in Fira, Oia or Imerovigli |
| Booking note | a caldera sunset cruise and any caldera-view room need booking weeks ahead in summer |
1. Pyrgos, the old capital nobody stops at
Before Fira took over, Pyrgos was Santorini’s capital, and it still looks the part: a hilltop knot of whitewashed lanes climbing to a ruined Venetian kastro, with views across the whole island rather than just the caldera. It sits inland, away from the cliff-edge towns, which is exactly why the tour buses skip it. Give it an hour on the way to or from the south of the island; there’s no ticket and no queue, just quiet streets and a church tower worth the climb.
2. Megalochori and a cave-cellar Assyrtiko tasting
Megalochori is wine country’s quiet half, a small village of low stone houses a short drive from Akrotiri, with none of Oia’s foot traffic. Santorini’s Assyrtiko vines grow low, coiled into basket shapes against the wind, in volcanic soil that never needed the American rootstock grafting most of Europe’s vineyards required after phylloxera. Several producers here run tastings in old underground cellars carved into the pumice rather than a modern tasting room, book a wine tour that includes one and you’ll taste the difference the soil makes.
3. Emporio’s kasteli, a fortress village most tours skip
Emporio, inland on the island’s south side, holds Santorini’s best-preserved kasteli, a fortified medieval quarter of stacked stone houses arranged so their outer walls formed a defensive perimeter against pirate raids. Windmills stand on the ridge above it. It’s a 20-30 minute walk of narrow lanes, free to wander, and gets a fraction of the visitors Oia’s castle ruin does despite being the more intact fortification of the two.
4. Is the climb to Ancient Thera worth it?
Yes, if you’re willing to earn the view. Ancient Thera sits on Mesa Vouno, a steep hilltop between Kamari and Perissa, reached by a climbing road or path with no shuttle. The hilltop ruins date from the 9th century BC through Roman and Byzantine rule, cost EUR 10 (a flat 2026 rate after Greece’s site-pricing reform), and open daily except Wednesday. The Ministry of Culture’s official page has current hours; almost nobody on a rental-car circuit makes the detour, which is the whole appeal.
5. Thirassia, the island across the caldera nobody visits
Thirassia split off from Santorini in the same eruption that carved the caldera, and it sits close enough that a short ferry from Athinios or a small boat from Ammoudi Bay reaches it in 20-30 minutes. A half day buys caldera views from the opposite side, lunch in the village of Manolas, and a break from every crowd on the main island, at a fraction of the effort a Nea Kameni volcano tour asks for.
6. Cable car or donkey down to the Old Port?
Take the cable car. The 588 steps down from Fira to the Old Port are lined with donkeys and mules carrying tourists for around EUR 10 a ride, a practice PETA and the Greek group Ippothesis have documented as overloading and mistreatment, not a quaint local tradition. The cable car runs the same route for EUR 10 one-way in a few minutes; walking the steps costs nothing. There’s no honest case left for the donkey.
7. The Fira-Oia caldera hike, done at dawn
The caldera-edge trail between Fira and Oia runs about 10km through Firostefani and Imerovigli, roughly 3-4 hours with stops, and a detour to Skaros Rock’s ruined fortress adds another hour. Walk it starting at sunrise instead of mid-morning and you get the same clifftop views without the heat or the tour groups that fill the path by 10am, particularly on the rougher, shadeless second half past Imerovigli.
8. Where should you actually watch the sunset?
Not from Oia’s castle wall, unless you arrive an hour early and don’t mind standing in a crowd. Imerovigli and Skaros Rock sit higher on the caldera rim with the same west-facing angle and a fraction of the people, and a caldera sunset catamaran cruise puts you on the water looking back at the cliffs everyone else is standing on. Basic sunset sailings run roughly EUR 34-70; full-day catamarans with a meal and open bar run EUR 110-160. For Oia itself in full depth, see our Oia guide .
9. Do you need a car for any of this?
Mostly, yes. Pyrgos, Megalochori, Emporio and Ancient Thera all sit off the KTEL bus network’s direct routes, which hub through Fira and rarely connect two outlying villages without a change. An ATV, quad or rental car (roughly EUR 20-80/day depending on season) covers all four in a day; Thirassia only needs the ferry.
Where to stay in Santorini
Caldera-view rooms in Fira, Imerovigli or Oia run EUR 300-1,000+ a night in peak season; Kamari and Perissa on the black-sand east coast run EUR 70-200 for the same dates, a short bus ride from everything on this list. Check current rates on Booking.com before deciding which side of that trade-off you want.
