Santorini packs an extraordinary range of experiences into its 76 square kilometers. From watching the sunset from the ruins of a Venetian castle in Oia to swimming at a beach made of black volcanic sand, the island delivers sights you won’t find anywhere else in Greece. Most attractions cluster around the caldera rim (Fira to Oia) and the eastern beaches (Kamari, Perissa). You’ll need at least 3 full days to cover the highlights; 5 days lets you add a wine tour and a boat trip to the volcano For more, see our Santorini weather by month (Explore our complete Santorini travel guide for more.)
Things to Do in Santorini: Caldera and Sunset Experiences
Watch the Sunset from Oia Castle
The sunset from the Byzantine castle ruins (Kastro) at the northwestern tip of Oia is Santorini’s single most famous sight. Arrive by 18:00 in summer (17:00 in spring/fall) to claim a spot on the fortress walls. The crowds are intense, up to 2,000 people on a July evening, but the view of the sun sinking into the Aegean behind the caldera is genuinely spectacular. Alternative sunset spots with fewer crowds: the lighthouse at Akrotiri (southwestern tip), Santo Wines in Pyrgos (with a wine glass in hand), or the path between Imerovigli and Fira. Free. Open 24/7. Oia is 11 km from Fira; the KTEL bus costs 2.30 EUR and takes 25 minutes For more, see our best time to visit Santorini.
Hike the Fira to Oia Caldera Trail
The 10.5 km (6.5 mile) path from Fira to Oia along the caldera rim is one of Europe’s finest coastal walks. The trail passes through Firostefani and Imerovigli before descending to Oia, with the volcanic islands of Nea Kameni and Palea Kameni in full view the entire way. Plan 3-4 hours with stops for photos. Start early (before 08:00) in summer to avoid the midday heat; there is zero shade on the path. Wear sturdy shoes, the surface is uneven volcanic gravel and cobblestones. Carry at least 1.5 liters of water per person. The path is well-marked with painted stones and signs. Free For more, see our Santorini events and festivals.
Take a Boat Tour to the Volcano and Hot Springs
Dozens of operators run daily boat excursions from the old port of Fira (Gialos) to Nea Kameni, the active volcanic island in the center of the caldera. A typical 3-hour tour (30-40 EUR) includes a guided hike to the crater rim (1.5 km, 130m elevation gain), where you can see sulfur vents and feel heat radiating from the ground, followed by a swim at the hot springs off Palea Kameni. The water at the springs is murky yellow-brown from iron and manganese, and it stains light-colored swimwear, so wear dark colors. Longer 5-6 hour tours (60-90 EUR) add stops at Thirasia island for lunch. Boats depart at 10:00, 11:00, and 14:00 daily from April through October For more, see our best neighborhoods in Santorini.
Things to Do in Santorini: Beaches
Red Beach (Kokkini Paralia)
Red Beach near Akrotiri is the island’s most photographed shoreline: a narrow strip of dark red and black sand backed by towering rust-colored volcanic cliffs. The contrast between the red rock, black sand, and turquoise water is striking. The beach is small (about 200m long) and gets packed by 11:00 in summer. Access requires a 5-minute walk over a rocky path from the parking area; the cliffs are unstable and landslides occur, so don’t sit directly under the cliff face. Sunbeds cost 10-15 EUR per set. There’s a small canteen for drinks and snacks. Free entry. The Red Beach is 12 km from Fira; KTEL bus to Akrotiri (2.30 EUR) plus a 15-minute walk For more, see our where to stay in Santorini.
Perissa and Kamari Black Sand Beaches
Perissa and Kamari are Santorini’s main beach resorts on the southeastern coast, separated by the Mesa Vouno mountain. Both have long stretches of coarse black volcanic sand that gets scorching hot in summer, water shoes are essential (you can buy them for 5-10 EUR at beach shops). Perissa (7 km) is the larger and more laid-back of the two with beach bars, tavernas, and a diving center (Santorini Dive Center, PADI courses from 65 EUR). Kamari (5 km) has a more organized feel with a beachfront promenade, higher-end restaurants, and an open-air cinema (Cine Kamari, June-September, 10 EUR). Sunbeds with umbrella cost 10-20 EUR per set depending on proximity to the water. Free entry. KTEL bus from Fira: 2.30 EUR, 20-25 minutes For more, see our Santorini travel tips and FAQ.
Vlychada Beach
Vlychada on the southern coast is a quieter alternative with dramatic white pumice cliffs sculpted by wind erosion into moonscape-like formations. The beach has dark grey sand, a small marina, and a handful of tavernas. It’s popular with nudists at the far southern end. Sunbeds cost 8-12 EUR. The Santorini Arts Factory and Tomato Industrial Museum are a 10-minute walk inland. KTEL bus from Fira: 2.30 EUR, 30 minutes. Vlychada rarely gets as crowded as Perissa or Kamari, even in August.
Things to Do in Santorini: History and Culture
Akrotiri Archaeological Site
Akrotiri is a Minoan Bronze Age settlement buried by the volcanic eruption around 1600 BCE, often called the ‘Pompeii of the Aegean.’ Unlike Pompeii, no human remains have been found here, suggesting residents evacuated before the eruption. The site is housed under a massive bioclimatic roof and a walkway lets you view multi-story buildings, pottery storage rooms, and well-preserved frescoes (the originals are in Athens’ National Archaeological Museum). Allow 1-2 hours. Open daily 08:00-20:00 (summer), 08:00-15:00 (winter, closed Tuesdays). Admission: 12 EUR (reduced 6 EUR). Combined ticket with Ancient Thera and the Museum of Prehistoric Thera: 15 EUR. Located 12 km from Fira.
Ancient Thera
Perched on the ridge of Mesa Vouno (396m) between Kamari and Perissa, Ancient Thera was inhabited from the 9th century BCE through the Byzantine era by Dorian Greeks, then Romans. The ruins include a theater, gymnasium, agora, and temples with panoramic views of both coastlines. The site is reachable by a winding road from Kamari (4 km, about 20 minutes by car) or a steep hiking trail from Perissa (1 hour uphill). Open 08:30-15:30, closed Mondays. Admission: 6 EUR. Bring water and a hat, there is no shade and the wind can be fierce at the summit.
Things to Do in Santorini: Wine and Food
Santorini Wine Tasting
Santorini’s volcanic soil and unique basket-shaped vine training system (kouloura) produce distinctive wines, particularly the crisp white Assyrtiko and the sweet dessert wine Vinsanto. The island has about 20 wineries, most offering tastings and tours. Top picks: Santo Wines in Pyrgos (largest cooperative, caldera-view terrace, tasting flights from 15 EUR for 6 wines), Venetsanos Winery near Athinios port (built into the cliff, tastings from 20 EUR), Domaine Sigalas in Oia (renowned Assyrtiko, tasting from 18 EUR), and Gavalas Winery in Megalochori (family-run, traditional methods, tasting from 12 EUR). Book ahead in July/August for sunset slots. Most wineries are open 11:00-20:00 daily April through October. A 4-hour guided wine tour with transport costs 80-120 EUR per person.
Take a Cooking Class
Several restaurants and farms on Santorini offer half-day cooking classes focusing on Cycladic cuisine: tomato fritters (tomatokeftedes), yellow split pea puree (fava), white eggplant dishes, and grilled seafood. Petra Kouzina runs classes from their farm near Megalochori (95 EUR, 4 hours, includes market visit and meal). Aktaion in Firostefani offers a more intimate class (75 EUR, 3 hours). Most classes include wine and a copy of the recipes. Book at least a week ahead in summer.
Things to Do in Santorini: Day Trips
Day Trip to Thirasia
Thirasia is the smaller island across the caldera, a quieter throwback to Santorini before mass tourism. Regular excursion boats from Ammoudi Bay (below Oia) and Athinios port make the 15-minute crossing (5-10 EUR each way). On Thirasia you can hike up 270 steps from the port of Korfos to the village of Manolas (or take a donkey for 10 EUR), eat at a family taverna with caldera views at half the price of Santorini, and swim at the black sand beach of Riva on the north coast. There’s little else to do, and that’s exactly the point. Boats run roughly hourly in summer from 09:00-18:00, less frequently in shoulder season.
Explore Pyrgos Village
Pyrgos was the capital of Santorini until 1800 and remains the island’s best-preserved medieval settlement. The village climbs a hill topped by the ruins of Kasteli Castle, with narrow whitewashed alleys, blue-domed churches (the Church of Theotokaki has a beautiful bell tower), and the best 360-degree views on the island from the summit. Pyrgos has about a dozen excellent tavernas, notably Selene (fine dining, tasting menu 95 EUR) and Kantouni (traditional, mains 12-18 EUR). The village is far less touristy than Oia or Fira. KTEL bus from Fira: 2.30 EUR, 15 minutes.
