Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City
Book on Viator →Operated by Diving Center Blue Dolphin Elounda · Bookable on Viator
Olous is a time machine you wear on your face. This snorkeling excursion lets you float above the sunken city of Olous, only about 50–80 cm down, with a guide who layers in Minoan context while you swim. I love the small group size (up to 8) and how the trip includes fins, mask, snorkel, and a wetsuit, so you can focus on the water, not shopping for gear.
There’s also a very practical bonus: if you’re nervous or new to snorkeling, the guides can teach technique and keep you comfortable at a steady pace. One thing to keep your expectations grounded: the ruins can be more about outlines and imagination than perfectly preserved relics you’d see in a museum.

Key highlights worth planning for

- Maximum 8 people means more attention, especially if it’s your first time in open water.
- All snorkel gear plus wetsuit is included, which helps you stay warm and comfortable.
- Beginner-friendly coaching—the guide can actively teach you snorkel basics during the trip.
- Shallow ruins (50–80 cm)—you’re not looking into deep water, you’re scanning the area calmly on the surface.
- Real sea life sightings alongside the ruins: fish, plus reports of octopus and starfish.
Olous Sunken City: why a shallow snorkel is the point
Olous is one of the most important Minoan-era cities in Crete, and this trip is built around a big advantage: the site sits very shallow. At roughly 50–80 cm under water, you’re snorkeling where you can see the ground, not sinking into a scuba-style depth. That makes the experience quieter and easier to manage for beginners, because you’re mostly moving horizontally, not fighting buoyancy.
It also changes how you “read” the place. You’re not getting a wall-to-wall collection of artifacts. Instead, you’re linking shapes you can make out—old road sections, building remnants, and sea grass edges—to what a city would have looked like above the water.
The best part is that you’re staring at the present while learning the past in real time. The guide’s job is to help you connect what you see (rubble, steps, paths) with the everyday life of a settlement that’s been underwater for thousands of years.

The 9:30 Elounda start and the short pre-snorkel briefing

The day begins at the Blue Dolphin Elounda center, located at the Aquila Hotel Elounda Village area in Elounda. The start time is 9:30 am, and pickup is arranged within the Elounda area for those who want it. The tour ends back at the same meeting point.
Before you get in the water, you’ll do two key things: a site-and-history presentation and getting kitted up. That intro matters because the snorkeling site isn’t one of those places where every second you spot a dramatic statue. With context, you can actually follow what you’re looking at—like the way an old street or building line would have guided movement through the city.
Plan for a calm rhythm rather than a rushed one. One review callout noted that getting ready took longer than expected, so if you’re the type who hates waiting around, bring patience—and wear clothes that are easy to change out of.
Gear and wetsuits: included comfort beats last-minute rentals

This excursion includes snorkeling equipment (fins, mask, snorkel) and a wetsuit. That’s a big value point because it removes the most annoying part of snorkeling travel: hunting for the right fit and hoping the gear is usable. When the equipment comes as part of the tour, the guide can also check your setup quickly and troubleshoot common problems right away.
In practice, wetsuits are also about more than warmth. They help your body stay comfortable in the water, and comfort makes it easier to concentrate on breathing and slow movement. For beginners, that’s huge—panicking usually comes from trying too hard while feeling exposed.
Also, the guide checks more than just fit. Multiple experiences highlighted that guides were attentive to mask comfort and pace, which reduces the “yank and fix” feeling that can ruin an early snorkel outing.
In the water at Olous: what you’re likely to see

Olous sits underwater just enough that you can study details without going deep. As you snorkel, you’ll follow the underwater remains through areas that can include old road lines and scattered building remnants. You may also notice sea grass around the site, which changes both visibility and how the underwater environment feels under the water.
Here’s the honest expectation to set: you shouldn’t count on seeing a perfectly preserved city block. Several experiences described the ruins as interesting but limited in what’s visually dramatic, so you’ll get the best results if you’re willing to use imagination. Think of it like reading a map with missing parts—you can still understand the layout if your guide helps you picture what used to be there.
The sea life side is where many people feel the payoff. Reports include lots of fish, and some outings mention octopus and starfish. Even when the ruins look subtle, that marine activity gives you a reason to look around constantly rather than focusing only on the seabed.
Your guide matters: patient coaching with real confidence

This is one of the few snorkeling trips where the guide’s teaching style is repeatedly part of the reason people recommend it. The tour is designed to be suitable for beginners, and guides are described as friendly, reassuring, and interactive. If you’re the type who gets anxious in new situations, you’ll probably appreciate having someone calm and focused right next to you.
Different guides came up in feedback, including Dimitri, Jackie, Julie, and Adam. The consistent pattern isn’t just knowledge—it’s patience. For first-timers, some guides were described as giving tips to improve technique, while others checked comfort frequently, kept a comfortable pace, and worked smoothly with weaker swimmers.
That’s practical, not just “nice.” In shallow snorkeling, your main skill challenges are mask comfort, steady breathing, and not rushing your head position. When your guide actively manages those basics, you end up spending your energy on enjoying the site instead of fighting your own breathing.
Transport, timing, and the real pacing of a 2–2.5 hour outing
The advertised duration is around 2 hours 30 minutes (about 2 hours for the activity itself, plus time around pickup and equipment). A big chunk of the experience happens in short phases: arrive, presentation, gear setup, transport to Olous, snorkel time, then back to the meeting point.
This pacing works well because it keeps the water time from feeling endless. In a shallow site, you can’t just “drift” for hours—conditions and comfort set the limit. A structured session also helps beginners, because the guide can keep the group together and adjust if someone needs extra time.
One more logistics note: the tour is near public transportation, and there’s a mobile ticket. That’s helpful if you’re staying somewhere else on the coast and want an easy way to plan your day without extra coordination.
Price and value: is $66.08 worth it?

At $66.08 per person, you’re paying for more than a boat trip—or at least, the value isn’t just about transportation. You get full gear (including a wetsuit), a guided visit with history explanation, and the small-group structure (max 8), which directly affects how much attention you receive.
If you’re coming from elsewhere in Crete or you’re staying in Elounda, the included pickup within the area also helps you feel the price more evenly. Without pickup, many snorkeling options become “find your own way to the site,” which adds stress and sometimes hidden costs.
Is it expensive? In the snorkeling world, it’s neither bargain-bin nor premium-luxe. It’s priced like a well-managed, guided half-day activity that’s aiming to make snorkeling comfortable for beginners. If you want deep-water diving or a long, multi-stop itinerary, this may feel short. But if you want a focused, teach-me-snorkeling experience at a shallow archaeological site, it’s reasonable.
The main value question for you is what you want to look at. If your dream is lots of clearly visible ruins, go in with a flexible mindset. If your dream is combining calm snorkeling, good guide support, and the thrill of seeing a submerged Minoan city in shallow water, it’s easier to feel satisfied.
Who should book this Olous snorkeling trip

Book this if you want a small, guided snorkel experience where learning is part of the deal. It’s a strong match for first-time snorkelers, nervous swimmers, and people who prefer a calmer pace and more personal attention. The guide support is repeatedly highlighted as reassuring and helpful, which is exactly what you want on your first try.
It also suits people who love blending nature and history without needing scuba experience. Since the site isn’t built for scuba exploration, it offers a different kind of connection: you see the underwater setting at snorkel depth and learn how the city likely functioned from the remaining traces.
Consider skipping—or at least tempering expectations—if you’re only interested in highly dramatic, clearly visible artifacts. The ruins can be subtle, and a few experiences emphasized that you need imagination to bring the city to life. If you’re the sort who needs instant visual fireworks, you might feel slightly underwhelmed.

I think it’s a great booking when you want a guided, beginner-friendly snorkeling outing with included gear and a small group. The shallow depth makes it approachable, and the guide coaching seems to be the difference between feeling tense and feeling confident.
