The best Santorini boat tours follow one classic caldera route: sailing past the volcanic hot springs at Nea Kameni, the Red Beach and White Beach, the island of Thirassia, and ending with the famous Oia sunset from the water. They split into three tiers: budget wooden sailing boats (€30–€50, no meal, 20+ guests), semi-private catamarans (€100–€180, BBQ and open bar, ~10–20 guests), and private yacht charters (€500+, fully customizable). For the best mix of comfort and views, book a small-group afternoon catamaran cruise so you watch the sunset from the calm water rather than the crowded Oia caldera path.
Santorini boat tours at a glance: which type is right for you?
Every operator runs roughly the same caldera loop, so the real decision is the type of boat. Here is how the three tiers compare on price, group size, and what you actually get on board.
| Tour type | Price (per person) | Group size | Duration | Food & drinks | Best for |
|---|---|---|---|---|---|
| Budget wooden sailing boat | €30–€50 | 20–60+ | 3–5 hrs | None (taverna stop on Thirassia) | Backpackers, the volcano + hot springs on a budget |
| Semi-private catamaran | €100–€180 | ~10–20 | 5 hrs | BBQ meal, wine, beer, soft drinks, hotel transfer | Couples, families, honeymooners — the sweet spot |
| Private yacht / motor cruiser | €500+ (whole boat) | Your group only | 4–8 hrs (flexible) | Custom menu & open bar, chosen departure time | Special occasions, full privacy, custom route |
Things to know before you book a Santorini boat tour
- The route: Almost every tour sails inside the caldera to the active volcano (Nea Kameni), the volcanic hot springs, the island of Thirassia, and the Red and White beaches.
- Morning vs. sunset: Morning cruises (roughly 10:00–15:00) mean warmer water, better swimming, and fewer crowds. Afternoon cruises (roughly 15:00–20:00) trade the swim time for the romantic Oia sunset from the water.
- Where they depart: Most catamarans leave from Vlychada Marina (best if you stay in the south, near Perissa or Kamari) or Ammoudi Bay below Oia (best for Oia and Imerovigli). Budget wooden boats usually leave from the main Athinios port — build in extra time for the traffic.
- Seasickness: The water inside the caldera lagoon is calm about 99% of the time. If you’re prone to seasickness, choose a larger catamaran over a small boat and avoid windy Meltemi days in July–August.
- Season: Most tours run mid-April to the end of October, with a few catamarans continuing into November. Peak small-group catamarans sell out weeks ahead from June to September — see the best time to visit Santorini for crowd and weather context.
- Booking:GetYourGuide lists the most tours with free cancellation; book the popular semi-private catamarans early in high season.
The 9 best Santorini boat tours for 2026
These are the boat tours we recommend, ordered from the best all-round value to fully private charters. Each one runs the caldera route; the difference is the boat, the group size, and what’s included.
1. Spiridakos Semi-Private Catamaran Cruise (Meals & Drinks) — best overall
Spiridakos is one of the most established names on the island, with decades of experience running catamaran cruises. This semi-private trip keeps the group small, sails the full caldera loop with swim stops at the Red and White beaches and the hot springs, and serves a freshly cooked Greek BBQ with wine, beer, and soft drinks included. The crew cooks on board, so you won’t be hungry — just don’t expect fine dining. It’s the option we send most first-timers to because it balances price, comfort, and food better than anything else.
Type: Semi-private catamaran · Group: ~10–16 · Duration: ~5 hrs · Departs: Vlychada · Includes: BBQ, drinks, hotel transfer · From ~€110.Check price & book →
2. All-Inclusive Luxury Catamaran Small-Group Sunset Cruise — best for the sunset
If watching the Oia sunset from the water is your priority, this all-inclusive afternoon catamaran is the pick. The small-group format means an unhurried sail along the caldera cliffs, a swim near the hot springs, and a position directly below Oia as the sun drops — the most photographed sunset in Greece, minus the land crowds. A full meal, wine, and an open bar are included, and the boat returns after dark.
Type: Small-group catamaran · Group: ~12–18 · Duration: ~5 hrs · Departs: Vlychada/Ammoudi · Includes: Meal, open bar, transfer · From ~€150.Check price & book →
3. Volcanic Islands Cruise with Hot Springs & Thirassia — best budget volcano trip
This is the classic, affordable volcano cruise on a large traditional wooden sailing boat. You hike the active volcano of Nea Kameni (about a 1.5-hour stop — wear proper shoes, not flip-flops), swim in the warm volcanic hot springs, and stop on Thirassia for lunch at a small port taverna. No meal is included on board, which keeps the price down. It’s the most popular way to tick off the volcano and hot springs without spending catamaran money.
Type: Wooden sailing boat · Group: 20–60 · Duration: ~5 hrs · Departs: Athinios · Includes: Volcano + hot springs + Thirassia (no meal) · From ~€35.Check price & book →
4. Santorini Gold Catamaran Cruise with Meal & Open Bar
A step up in comfort from the standard shared catamaran, the Gold cruise caps the group at around 20 guests and leans into the food-and-drink experience: a full cooked meal plus an open bar of wine, beer, and soft drinks the whole way. You still get the caldera route, hot springs, and beach swim stops, with morning and sunset departures available. Choose this if you want a lively, social catamaran day without paying for a private charter.
Type: Catamaran (open bar) · Group: ~20 · Duration: ~5 hrs · Departs: Vlychada · Includes: Meal, open bar, transfer · From ~€140.Check price & book →
5. Private Riva Motor Yacht Cruise with Meal & Open Bar — best luxury
For a milestone trip, this private Riva motor yacht charter is the most refined way to see the caldera. Because it’s a motor yacht rather than a sailboat, it covers the route faster — leaving more time at the hot springs, the Red Beach, and your chosen sunset spot. The whole boat is yours, with a private chef-prepared meal and open bar, and you set the departure time. It’s a honeymoon-grade experience priced per boat, not per person.
Type: Private motor yacht · Group: Your group only · Duration: ~4–5 hrs · Departs: Vlychada/Ammoudi · Includes: Private meal, open bar, flexible timing · From ~€800 (whole boat).Check price & book →
6. Private Custom All-Inclusive Caldera Motor Cruiser
This private motor cruiser is the most flexible option on the list: you build the itinerary with the captain. Want to skip a stop and spend an extra hour at the hot springs, add the Red and White beaches, or time the whole trip around the Oia sunset? You can. It’s all-inclusive with food and drinks on board and ideal for families or small groups who want privacy without the top-tier yacht price.
Type: Private motor cruiser · Group: Your group only · Duration: Flexible (4–6 hrs) · Departs: Vlychada/Ammoudi · Includes: Custom route, food & drinks · From ~€600 (whole boat).Check price & book →
7. Ocean Voyager 74 Premium Catamaran Sunset Cruise (BBQ & Drinks)
Run on the spacious Ocean Voyager 74 catamaran, this premium sunset cruise is a notch roomier than the standard shared boats, with generous deck and net space for the sunset. A fresh BBQ is cooked on board and drinks flow throughout, while the route covers the hot springs, volcanic cliffs, and the beach swim stops before parking below Oia for sunset. A reliable mid-to-premium pick for couples who want space without going fully private.
Type: Premium catamaran · Group: ~15–20 · Duration: ~5 hrs · Departs: Vlychada · Includes: Fresh BBQ, drinks, transfer · From ~€150.Check price & book →
8. Private Sunset Cruise with Barbecue & Drinks
A private sunset cruise built around the evening light and an on-board BBQ. With just your group on the boat, you get an unhurried sail to the sunset position below Oia, swim stops on the way out, and a grilled dinner with drinks as the sky changes colour. It’s a more intimate, better-value private option than a full yacht charter — popular for proposals, anniversaries, and small-group celebrations.
Type: Private sailing/catamaran · Group: Your group only · Duration: ~5 hrs · Departs: Vlychada/Ammoudi · Includes: BBQ dinner, drinks, transfer · From ~€550 (whole boat).Check price & book →
9. Private Catamaran Cruise with Food & Drinks
The catamaran version of a private charter: the stability and deck space of a catamaran, reserved entirely for your group. It covers the full caldera route with food and drinks on board and the freedom to adjust timings and swim stops with the crew. Choose this over the private motor yacht if you prefer the relaxed, low-and-wide feel of a catamaran and want the front nets to yourselves.
Type: Private catamaran · Group: Your group only · Duration: ~5 hrs · Departs: Vlychada/Ammoudi · Includes: Food, drinks, flexible route · From ~€700 (whole boat).Check price & book →
What you’ll see on the caldera route
Whichever boat you choose, the caldera loop hits the same highlights. Here’s what each stop is actually like.
The active volcano (Nea Kameni)
The Santorini volcano sits on the islet of Nea Kameni in the middle of the caldera. Budget boats include the easy (but rocky) crater hike; private tours can add or skip it on request. It’s a lunar-like landscape and one of the few active volcanoes in Europe.
The volcanic hot springs
The hot springs at Palea Kameni are warm (not hot) rust-orange water rich in sulfur and iron. You swim from the boat into the cove; the colour and faint smell are normal. Wear a dark swimsuit, as the minerals can stain lighter fabrics.
Thirassia, the Red Beach & the “7 Brothers” chapel
Boats stop at the small volcanic island of Thirassia for a taverna lunch, sail past the dramatic Red Beach and White Beach for a swim, and many pass the tiny “7 Brothers” Greek Orthodox chapel in Armeni Bay — built in the 1700s and reachable only by boat.
The Oia sunset from the water
On afternoon cruises, the finale is the Oia sunset watched from the calm water below the village — the same view that draws thousands to the castle walls, but from a far quieter vantage point. Check the current Santorini sunset times so you book a departure that lines up with golden hour.
Reality check: tips locals wish you knew
- The hot springs are lukewarm. They’re a warm, muddy cove — refreshing, not a spa. The sulfur can stain pale swimwear, so wear dark colours.
- Mind the wind, not the waves. The caldera lagoon is calm; it’s the open southern stretch toward the beaches that gets choppy on Meltemi days. Larger catamarans handle it better.
- Avoid the Athinios bottleneck. The main port gets jammed when cruise ships and ferries arrive. If your tour leaves from Athinios, leave early; catamarans from Vlychada or Ammoudi are far less stressful.
- What to bring: a dark swimsuit, a towel, reef-safe sunscreen, a light layer for the cooler evening sail, and proper shoes if your tour includes the volcano hike.
- Honeymooners: book a semi-private or private catamaran — see our guide to the best things to do in Santorini for couples to round out the trip.

Frequently asked questions
What is the best time of day for a Santorini boat tour?
It depends on your priority. The afternoon sunset cruise is the most popular because you watch the famous Oia sunset from the water, avoiding the land-side crowds. The morning cruise is better if you want to swim, as the water is calmer and warmer and the boats are less busy.
Can you swim in the hot springs in Santorini?
Yes. The volcanic hot springs at Palea Kameni are warm (not hot), rust-coloured water that you swim into from the boat. The water is rich in sulfur and iron, so the colour and faint smell are normal — and a dark swimsuit is recommended because the minerals can stain light fabrics.
How much does a Santorini boat tour cost?
Prices depend on the boat. A budget ticket on a large wooden sailing boat is about €30 to €50 per person. A semi-private catamaran cruise with a BBQ, open bar, and hotel transfer runs roughly €100 to €180 per person. Private yacht and catamaran charters start around €500 and are priced per boat, not per person.
Where do Santorini boat tours depart from?
Most catamaran cruises leave from Vlychada Marina in the south or from Ammoudi Bay below Oia, both with hotel pickup. Budget wooden boats usually depart from the main Athinios port. Pick a port close to your hotel to minimise transfer time, and allow extra time if you leave from Athinios.
Should I book my Santorini boat tour in advance?
Yes. From June to September the top semi-private catamarans sell out weeks ahead, so book as soon as your dates are set. Booking through a platform like GetYourGuide gives you free cancellation, so you can lock in a spot and adjust later if your plans change.
Are Santorini boat tours worth it?
For most visitors, yes — a caldera boat tour is one of the highlights of a Santorini trip. You see the volcano, hot springs, Red and White beaches, and the Oia sunset from angles you can’t reach by land. If you only do one activity on the water, a semi-private catamaran cruise gives the best balance of scenery, comfort, and value.
