Snorkeling Tour Santorini

Snorkeling Santorini visitors can book is mostly a side of a bigger trip, so I looked for tours where the swim is the point. Three came out: a catamaran with snorkel stops at $95, and two sea kayak trips at $140 and $151. If you want the broader choice, my guide to boat tours in Santorini compares all 16 trips. Prices are in US dollars from the listings, checked in October 2026, and booking links are affiliate links. I haven’t snorkeled on any of these tours, so I’ve kept to what the listings and the review snippets say.

My pick: the Vista Yachting Gold Catamaran at $95 for most people. It has 4.8 from 3,554 reviews, lists snorkeling equipment, and visits Red Beach, the hot springs and Mesa Pigadia beach. I’d pick a kayak trip instead if I wanted caves and cliffs and was a confident swimmer.

Snorkeling Santorini Greece

Snorkeling Santorini Greece style means volcanic coastline: rock, caves and colored beaches, not coral reef. The Greek National Tourism Organisation describes the island’s beaches as black, red and white sand with multicolored pebbles, on Visit Greece, and the cliffs drop straight into the water in places. What you see underwater depends on the day and the spot, and the listings don’t promise species or visibility, so I won’t either.

The Vista Yachting catamaran is the easy way in. It starts at Vlychada Marina, and the listing lists Red Beach for a swim and snorkel, White Beach and the Venetian lighthouse for views, the volcano hot springs, the caldera cliffs, and Mesa Pigadia beach for a swim, snorkel and BBQ lunch. A guide comes on board, and snorkeling equipment, life jackets, unlimited soft drinks and water are included. The cost is $95 for five hours.

Santorini Snorkeling

Santorini snorkeling from a kayak, one more way of snorkeling Santorini offers, is a different style: you paddle to the sea caves and slip in the water at the places you can only reach by paddle. The Serenity Kayak trip, called Sea Caves Kayak Trip with Snorkeling and Picnic, costs $151, takes seven hours and scores a perfect 5.0 from 353 reviews. The itinerary covers hotel pickup, the Akrotiri coastline, small caves and rock formations, Black Mountain for sea caves and snorkeling, and cliff jumping at White Beach. It includes a guide, sea kayak, snorkeling and safety equipment, dry bags, a towel, a sun hat, sunscreen, water and a picnic of local organic products.

There are limits. The listing excludes children under 14, non-swimmers and people over 280 lb (127 kg). It is also a long day. I’d only book the seven-hour version if I were fit enough for a few hours of paddling, and I’d check the wind forecast first on the Hellenic National Meteorological Service site, hnms.gr.

Best Snorkeling Santorini

The best snorkeling Santorini tours offer, by the numbers, are the two kayak trips, because both have a 5.0 rating, and the catamaran, because it has the most reviews. The Santorini Sea Kayak trip is the shorter option at three to three and a half hours and $140, with 5.0 from 266 reviews. It starts at the company’s base on Akrotiri Beach: park in front of Hotel Akrotiri and walk onto the beach. The schedule shows a 40-minute safety briefing, a guided tour with pass-by stops, a break of about 40 minutes for visiting and sightseeing, and 30 minutes of kayaking. The guide is BCU-certified, the listing says, and it includes snorkeling gear, dry bags, a hat, sunscreen, a picnic and liability insurance. There are 16 drop-off locations at the end.

If you only have a morning, this is the one I’d pick for snorkeling, because it takes less time than the catamaran trip and includes a pickup drop-off option. Compare the options in the table at the end of this page. Note that the listing says the details depend on the selected option, so check the option you choose.

Snorkeling Red Beach Santorini

Snorkeling Red Beach Santorini is on the itinerary of all three tours here. It is on the south coast near Akrotiri, a few kilometers from Vlychada Marina in a straight line, and the cliffs are red volcanic rock. Vista Yachting lists a swim and snorkel near the iconic red cliffs, Spiridakos lists a 30-minute swim, and Santorini Sea Kayak paddles past it on the way to Kampia beach and White Beach. The Sunset Oia catamaran allows 30 minutes of swimming and snorkeling at Red Beach before White Beach.

I’d check how close the boat gets before you plan around this stop. Some listings say ‘pass by’ or ‘photo stop, sightseeing’, which means you look from the boat, not swim. Sail Away, for instance, lists Red Beach and White Beach as five-minute photo stops. If swimming at Red Beach matters to you, choose a listing that says swim or snorkel. My page on catamaran tours in Santorini gives the stop lists for six boats.

Can You Snorkel in Santorini

You can snorkel in Santorini on most full-day catamaran tours, because gear is routinely included. Gear is listed on the Sunset Oia luxury trip, on Vista Yachting, on Volcano Yachting, and on all three private catamarans. The private boats are on my private boat tour page. If you rent a boat yourself, both rentals include snorkeling equipment too, and I’ve covered the terms on the boat rental page.

For an evening swim, several sunset tours include a swim stop. My sunset cruise page lists which ones, and my page on sailing in Santorini shows the swim times on a sailboat. A long dive isn’t part of any of these trips: they are snorkeling and swim stops, not diving.

What I’d Bring

For snorkeling in Santorini, the kayak listings include dry bags, a hat and sunscreen, and the catamaran lists snorkeling equipment and life jackets, so you mainly need swimwear and a towel unless the listing provides one. Serenity Kayak lists a towel, a sun hat and sunscreen. Santorini Sea Kayak lists a hat and sunscreen but no towel. I’d also bring a waterproof phone case or use the dry bags for your phone, since the cliffs and caves are worth photographing. These are my own suggestions, not claims from the operators, and the weather can change what you need.

How I’d Choose a Snorkeling Trip in Santorini

My checklist:

1. Not confident in the water for snorkeling Santorini style? Pick the catamaran. It lists life jackets, a guide and a meal, and children are not excluded in the listing.
2. Short on time? Santorini Sea Kayak takes three to three and a half hours.
3. Want the full adventure? Serenity Kayak, seven hours, with cliff jumping and a picnic.
4. Want the swim stops of a long cruise instead of a snorkeling tour in Santorini? See the other catamarans on my guide to boat tours in Santorini.

Whichever snorkeling Santorini option you book, each offers free cancellation up to 24 hours ahead. When the forecast is windy, ask the operator whether the route changes. Everything here is from the listings, so recheck gear and options on the booking page, or go back to the home page for other cities.
