Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City
Book on Viator →Operated by Diving Center Blue Dolphin Elounda · Bookable on Viator
A Minoan city is under your fins. This guided snorkel around Olous in Elounda takes you over submerged remains of one of Crete’s earliest major cities—shallow enough to feel calm, with a guide there to help you look the right way.
I like the small group setup (max eight), which means you actually get attention instead of floating off like a loose noodle. I also like that everything you need is included: fins, a mask, a snorkel, and a wetsuit, so you’re not doing last-minute gear shopping.
One possible drawback: the ruins are shallow but not always “wow” in the movie-poster sense. You’ll see interesting structure and rubble, but you may need to use some imagination to picture the old street plan—especially if you were expecting lots of intact relics.

Key highlights worth your morning

- Max 8 people keeps the snorkeling relaxed and the guiding personal
- All snorkeling gear included (fins, mask, snorkel, wetsuit)
- Beginner coaching built in, including mask comfort and technique tips

Olous Sunken City: Why Snorkeling Here Feels Different

Olous is a rare kind of site: submerged remains that are close enough to the surface to explore with snorkeling, and not really the same thing as scuba wreck-diving. The tour focuses on what’s visible at around 50–80 cm depth—right where your eyes can do the work.
What makes this experience click is the pairing of underwater time with a brief on-land orientation. If you know roughly where you are in the city, ruins stop looking like random stones and start looking like clues.
And yes, it’s also about quiet water. You’re not chasing waves or big currents. You’re there to look carefully, breathe comfortably, and let the site make sense at a human pace.

From Elounda to Olous: Timing, Pickup, and What the Morning Looks Like

This tour runs about 2 hours 30 minutes in total time (with the snorkeling itself listed at about 2 hours). It starts at 9:30 am, so you’re getting your water time early—often the best move for comfort and visibility in the morning.
Your meeting point is at the Blue Dolphin Elounda center in the Elounda area (near the Aquila Hotel / Elounda Village area). The tour ends back at the same meeting point, so there’s no awkward “now what?” travel at the end.
Pickup is offered within Elounda, and it’s arranged individually. If you’re staying anywhere in that zone, this is one less thing to plan, and it matters because your morning is already split between fitting gear and getting in the water.
The Gear Setup That Makes or Breaks Beginner Snorkeling

For snorkeling trips, gear can be the difference between fun and fiddly frustration. Here, you get fins, a mask, a snorkel, and a wetsuit included, which is a big value point at this price.
I like that the tour isn’t just handing you equipment and pointing at the sea. Guides check how your mask sits, how comfortable you feel, and the pace you’re swimming. In practice, that’s what helps first-timers relax instead of spending the whole swim adjusting their face gear.
One real-world thing to note: some people find the prep takes longer than expected. If you’re the type who hates waiting, plan to arrive early enough to settle in. A slower gear fitting isn’t always a dealbreaker—it can also mean the guide has time to help you get comfortable before you go under.
Underwater Expectations: What You’ll Actually See at 50–80 cm

Here’s the honest picture. Olous under the water is mostly submerged structure and rubble—parts of a city you have to interpret, not a theme park of intact buildings. Because the remains sit around 50–80 cm, you’re close to the seabed, but the visible elements may be limited depending on where you’re positioned and how you’re looking.
Multiple guides in the reviews emphasized walking through the city layout in a way your brain can follow. That’s why the pre-snorkel history talk matters. With that mental map, the underwater pieces you see—like old paths or building remnants—start to look connected.
One review called out that you might need imagination. That’s not a failure of the tour; it’s just reality. You’re seeing a city that sank thousands of years ago, so it’s more like evidence than a perfectly preserved street.
What you can feel good about: even when the ruins aren’t “lots of relics,” the site is still interesting. And the shallow depth makes it easier to stay calm, keep your head up, and enjoy the view without wrestling a complicated water routine.
The City Story: How the Guide Turns Stones into a Street Plan
A standout element here is the guide-led presentation before you enter the water. You get a talk about Olous and what you’re likely to see, plus guidance while you snorkel among the remains.
In reviews, different guides were praised for being patient and interactive—especially with people who felt nervous. Names you’ll see mentioned include Dimitri, Jackie, Julie, and Adam. Each gets credit for making the experience feel manageable, not intimidating.
I think this is one of the tour’s biggest strengths: the history is used as a tool. Not a lecture for the sake of a lecture. You’re meant to leave that first briefing ready to spot features and connect them to the city story.
So when you’re floating above the old road-like structures and building remnants, you’re not just seeing rocks. You’re trying to picture how daily life might have worked there.

The Snorkel Itself: Calm Water, Small Group Pace, and Safety Checks

The snorkeling part is guided and designed to be low-stress, even for beginners. The operator includes technique coaching, and guides help people get comfortable with masks, breathing through a snorkel, and staying relaxed at the surface.
Because the group is limited to eight, the guide can actually keep an eye on everyone’s comfort. That matters most when someone is struggling or simply nervous. One review specifically praised a guide for reassuring a guest who was quite anxious, and that same theme showed up across multiple positive comments.
The pace described in reviews is also on the gentle side. People noted that guides checked in regularly to make sure masks felt okay and that swimming pace matched everyone in the group.
Practical tip: if you’re even a little unsure in open water, tell your guide early. The tour is built for supportive coaching, and the better you communicate, the more you’ll enjoy the time you’re paying for.
Sea Life Bonus: Fish and Small Encounters Along the Ruins

Olous isn’t just a historical stop. You also get the normal snorkeling payoff: seeing marine life up close.
Reviews mention lots of fish, plus sightings like octopus and starfish. You might also spot sea grass around the ruins area, which can help create a calmer, natural viewing zone.
This is one reason I’d put this tour on the “worth it” list for people who don’t want to plan a full day in the water. You’re getting history AND wildlife in the same 2-hour snorkeling session.
Just keep expectations flexible. Underwater visibility and wildlife movement change. The tour is about the combination—ruins as your focus, sea life as the cheerful bonus.
Price and Value: Is $66.08 Worth It?

At $66.08 per person, this is positioned as a mid-range morning activity. The value comes from three things that are hard to replicate if you DIY it:
- You’re getting full snorkeling gear included (so you don’t pay separately for rentals)
- You’re paying for a trained guide who teaches basics and manages the group pace
- You’re paying for access to a specific underwater site that’s designed for snorkeling rather than scuba logistics
Could you theoretically snorkel in Crete on your own? Sure. But you’d be making a lot of guesswork about where to go and how to interpret what you’re seeing once you arrive.
This tour aims to reduce the guesswork. And given how many reviews rate it highly (an overall 4.6 with strong recommendation), the price looks fair for a short, structured experience with gear and guiding included.
One note on expectations: if you want lots of clearly visible artifacts, some people feel the underwater remains require imagination. That doesn’t make it bad. It just changes what you should expect for your money.
Who This Tour Fits Best—and Who Might Be Happier Elsewhere
This is a strong fit if you want:
- a beginner-friendly introduction to snorkeling
- a small-group experience with real guidance
- a morning activity in Elounda that’s more than just floating for photos
It also works well if you like history but don’t want a museum-only approach. You’re seeing the setting where the story happened—under water—at a depth that’s typically easier to manage.
You might think twice if:
- you expect a site full of intact ruins you can immediately recognize like postcards
- you prefer minimal waiting time, because some people found the prep slower than they’d like
If your main goal is maximum underwater “stuff,” you may be slightly disappointed. If your goal is to understand a place and enjoy calm snorkeling with good coaching, you’ll likely be happier.
Should You Book the Olous Snorkeling Excursion?
I’d book it if you’re traveling from Elounda and want a structured, guided morning that mixes beginner snorkeling, included gear, and a real attempt to help you understand Olous. The shallow depth makes it accessible, and the small group size keeps the experience personal.
I’d also book it if you’re the kind of traveler who likes building a story from clues. This is one of those experiences where your imagination does some of the work, but that’s also what turns it from sightseeing into understanding.
If, on the other hand, your dream snorkeling is all about highly visible wreckage or dramatic underwater monuments, you might be better with a different style of trip. Olous is subtle. It asks you to look closely.
