Santorini is not your typical Greek island beach destination. The beaches here are black, red, and occasionally both at once, shaped by centuries of volcanic activity and unlike anything you’ll find on the sandier islands of the Cyclades. If you’re coming for white sand, you’re on the wrong island. If you’re coming for something genuinely dramatic, you’re in exactly the right place.

The beaches fall into two camps: the eastern coast, where most of the action is, and the wilder southern coast, where the scenery takes over. Here’s what you need to know about both.

Kamari

Kamari is one of the most popular beaches on the island and easily one of the most organized. Located on the eastern coast, it’s a long black sand and pebble beach with the imposing rock of Mesa Vouno rising from the sea at one end, the same rock that separates it from Perissa on the other side. Sun beds, umbrellas, water sports, beach bars, tavernas, and hotels line the waterfront, making it a full-day destination rather than just a swim stop. Windsurfing and water skiing are popular here, and the village behind the beach has plenty of shops if you feel like browsing between dips.

Perissa

About 15 km from Fira, Perissa sits on the opposite side of Mesa Vouno from Kamari and shares the same volcanic black sand and crystal clear water. It’s slightly more relaxed in character, with a good range of accommodation in the village right behind the beach, which is useful to know if you’re planning to base yourself here rather than in Fira. The two beaches look very similar but feel different: Perissa has a younger, more low-key crowd and a less resort-heavy atmosphere.

Monolithos

North of Kamari on the eastern coast, Monolithos is the one to head to if you want a quieter day at the beach. It’s more family-oriented than its neighbors — there’s a football pitch, a basketball court, and a playground — and noticeably less crowded even in peak season. The black sand and calm, shallow water make it a good option for families with younger children.

Perivolos and Agios Georgios

These two beaches sit side by side on the southern coast and are essentially one long stretch of black sand. Perivolos is the livelier of the two, with beach bars, tavernas, and water sports facilities along the shore. Agios Georgios, just 500 meters further along, is the quieter alternative: same beach, fewer people, slower pace. If you want the southern coast vibe without the full party atmosphere, Agios Georgios is the one to pick.

Vlychada

Also on the southern coast, Vlychada tends to attract visitors who’ve already done the main beaches and are looking for something a bit different. The white pumice cliffs behind the beach give it an almost lunar atmosphere and it’s one of the more visually striking spots on the island and still relatively under the radar compared to the eastern beaches. Go for the scenery as much as the swimming.

Red Beach

The most photographed beach on Santorini and one of the most recognizable in all of Greece. Located 8 km southwest of Fira near the village of Akrotiri, the Red Beach gets its name from the towering red and black volcanic cliffs that frame it. The contrast with the deep blue Aegean is genuinely spectacular, and snorkeling among the underwater volcanic rocks is a popular activity here.

A critical word of warning: due to severe recent landslides and ongoing rockfalls, local authorities frequently place total access bans on parts of the beach and the cliff path. Venturing near or sitting directly under the red cliffs is strictly forbidden and highly dangerous. If you do attempt the foot path, it features steep elevation gains and loose, uneven terrain. Sturdy footwear is non-negotiable, so sandals and flip-flops are completely unsuitable. The beach is reachable on foot from the Akrotiri archaeological site, by bus from Fira, or by boat as part of a catamaran tour. Given the access constraints, the boat option is worth considering.

Best time to visit

May, early June, and September are the sweet spots. The sea is warm, the crowds are manageable, and the light is beautiful. July and August are peak season. The eastern beaches in particular get very busy, and the heat is serious. The Red Beach path in full August sun is not for the faint-hearted. October is increasingly popular for a quieter late-season visit when most beaches are still perfectly swimmable.

Getting to Santorini

By air

Santorini has its own airport (JTR) with direct flights from across Europe during the summer season — easyJet, Ryanair, British Airways, TUI, and others all fly in. The flight from London takes around three and a half hours.

From the US, United Airlines operates seasonal direct flights from New York/Newark (EWR); travelers from other US cities will typically connect via Athens or another European hub. The airport is small and gets extremely busy in summer, so if you’re flying in July or August, book as early as you can.

By ferry

The ferry is the classic way to arrive. Sailing into the caldera is one of those travel moments that actually lives up to expectations. From Piraeus in Athens, there are up to 10 daily crossings in summer, with journey times ranging from around 5 hours on a high-speed catamaran to about 8 hours on a conventional ferry. Ticket prices for standard conventional ferries start from around €47 to €59, while high-speed catamarans cost significantly more.

Santorini is also well connected by ferry to nearby Cycladic islands such as Naxos, Milos, Ios, or Mykonos, as well as to islands further away: Crete or Rhodes.

One important note: Santorini’s ferry port, Athinios, sits at the bottom of steep cliffs and is not walkable to Fira, Oia, or any of the beach towns. Have a plan for onward transport before you arrive — a pre-booked transfer is the easiest option, especially in peak season when taxis are thin on the ground.

Getting to the beaches

Most of Santorini’s beaches are reachable by bus from the central station in Fira, with regular services to Kamari, Perissa, and Akrotiri running throughout the summer. For more flexibility, especially if you want to combine several beaches in one day, renting a car or ATV is the practical option. Taxis are available but can be hard to find at peak times, so don’t rely on them for getting back from a remote beach at sunset.

Where to stay

Fira is the most popular base: central, well-connected, and with the caldera views that Santorini is famous for. For something closer to the beaches, Kamari and Perissa both have a solid range of accommodation at every price point, from budget guesthouses to comfortable mid-range hotels steps from the water. If you’re after the full luxury Santorini experience with infinity pools, caldera sunsets, the works, the clifftop hotels in Oia and Imerovigli are where the island really delivers, though you’ll need transport to get to the beaches from there.

Organized Tours

A catamaran tour is one of the best ways to see the southern beaches — Red Beach, White Beach, and the volcanic hot springs — in a single trip without worrying about parking or cliff paths. Most tours include a BBQ lunch and drinks on board, and the sunset versions sell out well in advance during peak season.
