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.

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
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
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?
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.
