The Three Best Snorkeling Spots in Santorini

Santorini has a reputation for being the ultimate romantic destination, a perfect paradise for lying back and enjoying the sun. But Santorini has a lot more to offer, whether you’re traveling as a pair, in a big group, or solo.

One of the benefits of choosing Santorini as a holiday destination is the stretches of coastline which means there are many beaches and coves to explore – and this also means perfect snorkeling spots. And this is what we’re going to talk about today, no matter if you’re a confident diver already, or just want to get your first taste of underwater life.

So where are the best spots on the island? I mapped out the seven spots you need to hit before flying home. Beware, these gorgeous locations are sure to have you booking that flight you have been thinking about!

1. Caldera Beach

You may have already heard of Santorini’s famous caldera. It’s important to understand that Santorini is an active volcano – back in the days of the Minoan civilization, this volcano erupted, leaving behind a volcanic depression.

The outer edge of the volcano is what forms Thira, the main island in Santorini today, whilst later eruptions created the smaller islands of Palea Kameni and Nea Kameni.

Today, the volcano remains active, but it hasn’t erupted since the 1950s, so you’re perfectly safe to explore the waters of the caldera.

Usually, most people get to the caldera by boat, but this beach is the only one that allows you to get into the caldera water without trying out your sea legs.

This quiet spot is perfect for those who want to get away from the hustle and bustle of Santorini’s main beaches. The water is deep and clear – just make sure that you don’t mind having some animal companions, as there are plenty of fish here!

2. Kamari Beach

If you’re looking for a beach that offers hustle and bustle to get you in the holiday mood, then Kamari is the place for you. It’s a great option for families, or for holidaymakers who are looking for plenty of activities to keep them occupied, even after they’ve been snorkeling.

This black sand beach is two kilometers in length, meaning that you won’t be crammed on top of another swimmer. The water is clear, but it does drop off quickly, so make sure that you’re comfortable and supervise any younger children.

There are also some artificial rock formations away from the main shoreline, so you can head out away from those who are paddling and really get the most out of your snorkeling experience.

On the right-hand side of the beach, there is a large rock that separates Kamari and Perissa. Make sure to take care here, as it’s very appealing for snorkeling, but there can be strong currents that will pull you around to Perissa.

It’s hard to get back again without getting on a boat – which you’re unlikely to have money to pay for in your swimming suit!

3. Nea Kameni

This tiny uninhabited island has been created as a result of the eruptions from the Santorini volcano and is a popular spot for people looking to snorkel. The underwater geology here looks like an alien planet.

You can also take a boat to the inlet of neighboring Palea Kameni where there are some natural hot springs, which contain iron and magnesium, and are known for their therapeutic benefits.

Just know the water is murky brown. Make sure to take a warm bath before cooling off in the refreshing sea water.

Make sure to check the conditions of the water before you head to this small island, as it can get a little choppy when the wind picks up.

4. Ammoudi Bay

This spot sits directly below the cliffs of Oia and it is a mandatory addition to your list. I cannot overstate how incredibly clear the turquoise water is down here.

There is no actual sandy beach. You walk past the seafood tavernas, climb over some boulders, and dive straight off the rocks into the Aegean. The rocky seabed teems with sea urchins and damselfish.

Ammoudi is also famous for cliff jumping at the small islet of Agios Nikolaos right offshore. The swim out to the jumping rock is one of the best short snorkeling routes on the entire island.

5. Red Beach (Kokkini Paralia)

You cannot talk about Santorini without mentioning Red Beach. The contrast of the blood-red volcanic cliffs dropping into the blue water creates a surreal snorkeling backdrop that looks like another planet.

Do not just swim in the dead center. The sandy middle section is boring underwater. You need to snorkel around the large rock formations near the far edges to see the most marine life. The rocks are extremely sharp, so pack proper water shoes.

6. White Beach (Lefki Paralia)

This is Red Beach’s isolated neighbor. The white pumice cliffs extend beautifully underwater, creating shallow, crystal-clear volcanic pools and small sea caves that are incredibly fun to explore with a mask on.

Because you can basically only reach it by taking a small boat from Akrotiri, it keeps the lazy tourists away. The seabed is covered in large white pebbles that reflect the sunlight and make the water ridiculously bright.

7. Mesa Pigadia

I am giving you this hidden gem as a reward for actually reading this far. Mesa Pigadia sits on the southern coast and features a dark black pumice seabed.

It has a network of underwater caves and a healthy amount of marine life that thrives away from the heavy tourist boat traffic. When the northern winds batter the rest of the island, the water here stays dead calm. It is the perfect backup plan when the weather turns on you.
