Olous is a city you can see without a boat. This guided snorkelling outing takes you to the sunken Minoan remains at about 50 to 80 cm underwater, with a calm pace and a guide who keeps you safe and smiling. I also like that this runs as a small group (max 8), so the guide can actually spend time with you, not just point and rush.

The best part is the mix of simple snorkel coaching plus a clear history intro, so the rubble turns into something you can picture. You’ll also get full gear, including fins, mask, snorkel, and wetsuit, which saves hassle in the morning. One consideration: what’s visible underwater is limited, so you do need some imagination to connect the underwater traces to a whole ancient city.

Key highlights to look for

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Key highlights to look for

  • Max 8 people means a more personal snorkelling experience and easier check-ins
  • All snorkel gear included (mask, snorkel, fins, wetsuit) so you can travel lighter
  • Shallow ruins at 50 to 80 cm make it snorkel-friendly and not scuba oriented
  • Beginner support is real, with guides who calmly coach nervous first-timers (examples include Dimitri, Jackie, Adam, Julie)
  • You’ll see plenty of sea life, including fish, and sometimes octopus and starfish
  • A short history presentation helps you understand streets, buildings, and the general layout you’re swimming over

Olous at 50 to 80 cm: what shallow ruins really feel like

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Olous at 50 to 80 cm: what shallow ruins really feel like
Olous sits underwater in a way that’s unusual. You’re not suiting up for a long, deep swim. Instead, you’re in very shallow water, around 50 to 80 cm, where the seabed is close enough to inspect and the surface stays nearby.

That shallow depth shapes the whole experience. It tends to feel quieter and more relaxed than deeper snorkel spots, and it also changes what you’re looking at. You’re often reading the ruins like a map, not admiring towering, intact monuments. It’s the kind of place where the moment makes sense after you get context from the guide.

If you like experiences that feel thoughtful rather than rushed, this one has that energy. The water is calm, the guide stays engaged, and you’re there to notice details you might otherwise miss.

Meeting at Blue Dolphin Elounda: timing and the fitting routine

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Meeting at Blue Dolphin Elounda: timing and the fitting routine
Your day starts at the Blue Dolphin Elounda base area, near Aquila Hotel in Elounda Village. The tour starts at 9:30 am, and you’ll return back to the same meeting point at the end. If you booked pickup, it’s arranged individually within the Elounda area.

Once you arrive, expect the morning rhythm common to small-group snorkel tours: you check in, then get set up with your gear. Multiple reviews point out the staff are friendly and patient, but one person also noted the prep can take longer than expected. So if you dislike waiting, plan to arrive a bit earlier and keep your morning unhurried.

A simple practical tip: if you can, come already in swimwear. That makes the wetsuit fitting stage faster and less stressful. With a group of up to eight, the crew can usually keep things organized, but wetsuits and mask fitting still take time.

The history intro that turns rubble into a story

Before you head out into the water, you get a presentation about the site and history. This matters more than you might think, because Olous underwater does not look like a dramatic, fully preserved city. What you see tends to be structural traces: parts of streets, steps, and building remnants, plus areas of sea grass and rubble.

When the guide explains what you’re likely swimming over, the whole thing clicks. Reviews mention that guides point out architectural features, and they encourage you to use your imagination without losing the thread of what you’re actually seeing. Guides such as Dimitri and Julie are highlighted for combining facts with clear explanations, while Jackie and Adam show up in reviews as supportive and interactive.

Think of it like this: the talk gives you a “then and there” mental picture, and the snorkel time lets you verify it with your eyes at close range. That pairing is what turns a simple swim into a meaningful morning.

Tiny-group snorkelling training for beginners who feel nervous

This tour is built for beginners, and the coaching style shows up in the reviews. Guides actively teach snorkel technique rather than assuming everyone already knows how to breathe comfortably with a mask and snorkel. That’s a big deal if you’re new, because confidence affects everything: your breathing, your pace, and whether you enjoy the ruins.

In small groups, a guide can also adjust on the fly. Several reviews mention regular check-ins, mask comfort checks, and reassurance for someone anxious in the water. One account specifically calls out how a guide stayed calm and encouraging, which is exactly what you want when you’re trying something new.

Group size also affects how the experience feels. With up to eight people, you’re not fighting for space, and the guide can notice if someone is struggling. That usually means the snorkel is more relaxed, with a pace that works for different swimmers.

You do want a moderate physical fitness level, mainly because snorkelling still requires some comfort in the water and the ability to follow instructions.

What you’ll actually see underwater: streets, steps, and temple areas

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - What you’ll actually see underwater: streets, steps, and temple areas
Olous is described as one of the most important Minoan cities, but you’re not going to see it like a museum model. Instead, you’re swimming above traces in shallow water where the city’s layout is suggested through what remains.

Reviews describe seeing a main street, house remains, and temple-related areas, along with steps and other structural pieces. Some people mention following the ruins from one area to another, with sea grass along parts of the route. The underwater story often plays out as a sequence: a first structure, then a clearer sense of the path or public area as you move.

Here’s the honest takeaway: visibility is not the main event. You’re not guaranteed to see “lots of relics” in the dramatic way you might picture. Instead, you’ll see enough to understand the idea, and then the guide helps you connect it. One reviewer put it simply, it’s amazing to think of a 5,000-year-old city underwater, but you will use your imagination to fill in the rest.

If you’re the type who enjoys historical places even when they’re fragmentary, you’ll likely love this. If you only want perfectly intact ruins, you may find it underwhelming.

Sea life on the route, plus those unforgettable extras

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Sea life on the route, plus those unforgettable extras
Snorkelling at Olous isn’t only about stones. It’s also about sea life around the ruins, which can make the water feel alive even when the architecture is subtle.

People mention seeing lots of fish, and some add-ons pop up in reviews, like octopus and starfish. Those moments are often what people remember after the history fades slightly. Shallow areas also tend to make it easier to spot wildlife because you’re not far from the seabed.

The guide also helps you notice what’s around you, pointing out what to look for among the structures and sea grass. That’s another reason the experience matters: you’re not just swimming, you’re learning how to observe.

Gear and comfort: why included equipment is part of the value

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Gear and comfort: why included equipment is part of the value
You get the full snorkelling setup: fins, mask, snorkel, and a wetsuit. For me, that’s a major part of the practical value. It removes the “where do I rent gear today” stress and ensures you’re using equipment suited to local conditions.

Wetsuits also make a difference in comfort in the water. Even in shallow snorkel locations, feeling cold can ruin the experience quickly. With gear included, you can focus on technique and noticing the ruins.

The guides also handle the comfort checks. Reviews mention guides checking masks and staying patient, especially for beginners. When you’re new, a small issue like a mask that leaks or a snorkel position that feels wrong can turn into a distraction. Having staff troubleshoot early helps you settle in faster.

Price and value: what $66.08 buys you in a real morning

Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City - Price and value: what $66.08 buys you in a real morning
At $66.08 per person, you’re paying for more than just access to a snorkel spot. You’re paying for a guided experience with history context, equipment included, and transport from the Blue Dolphin Elounda base to Olous.

This is where value comes down to priorities. If you’re a beginner, the included coaching can be worth a lot. It’s easier to justify spending when the guide helps you feel comfortable and safe, rather than leaving you to figure it out.

If you’re an experienced snorkeller who already has your own gear, the added value is still the interpretation. You’re not just swimming over rocks. You’re getting help connecting what you see to a Minoan city layout.

My advice for judging value: think about how much you would pay in your home area for a guided activity that includes both gear and instruction. If that number feels high, this price may feel reasonable, especially with a small group size.

Who this tour fits best, and who should think twice

This tour makes sense if you want a calm, beginner-friendly snorkel with a historical focus. It’s also a good fit for couples and families looking for a structured morning, since the group stays small and the guide manages comfort actively.

It’s especially suitable if you like learning with your eyes. If you enjoy tracing streets and imagining daily life based on fragments, you’ll get more out of Olous than someone expecting pristine ruins.

Think twice if your main goal is seeing lots of clearly preserved artifacts. The city’s underwater remains are real, but they’re not presented as a fully intact site. You will need the guide, and you’ll need your imagination, at least a bit.

Also, because there’s a moderate physical fitness requirement and you’ll be in the water for a set snorkel time, it may not be ideal for anyone who wants a totally seated, zero-effort activity.

Should you book Olous snorkelling with Blue Dolphin Elounda?

I’d book it if you want a small-group snorkel that feels safe, beginner-friendly, and grounded in storytelling. The included gear lowers friction, the shallow water keeps things approachable, and guides like Dimitri, Jackie, Adam, and Julie show up in past experiences as supportive and interactive.

I wouldn’t prioritize it if you need dramatic, clearly visible ruins. Olous is subtle by nature. Your enjoyment depends on whether you’re excited by the idea of an ancient city reduced to traces, and whether you’re okay mentally rebuilding what the water took away.

If you match those expectations, this is the kind of morning that gives you a different photo and a better memory than another beach stop.
