Olous – Guided Snorkelling Excursion to Discover Olous Sunken Ancient City

Ancient streets lie beneath Elounda’s calm water. This small-group outing lets you snorkel over the shallow remains of Olous, an important Minoan-era city, while a guide explains what you are seeing. I like the groups of no more than eight, which make it easier to hear the guide and get help in the water. I also like that fins, mask, snorkel, and wetsuit are included.

The main caution is simple: the ruins are subtle. You will not see a perfectly preserved underwater city. Much of the site consists of scattered stonework, an old road, steps, and traces of buildings that require some imagination. The water is only about 50 to 80 centimeters deep, so this is more an archaeological story told from the sea than a dramatic underwater spectacle.

The outing takes about two hours and 30 minutes, including preparation and transport from the Blue Dolphin Elounda center. Patient guides such as Dimitri, Julie, Jackie, and Adam have helped beginners find their rhythm, but allow extra time for getting fitted and ready. One person specifically found the preparation slow, while others valued the careful instruction.

Key points to know before booking

• The ruins sit in very shallow water, around 50 to 80 centimeters below the surface, making the site approachable for beginners.
• Small groups make a real difference, with a maximum of eight people and individual pickup available within the Elounda area.
• All main snorkelling equipment is supplied, including fins, mask, snorkel, and wetsuit.
• The guide adds the meaning, explaining the ancient streets, buildings, temple area, and daily life suggested by the remains.
• Marine life is part of the outing, with fish, octopus, and starfish reported alongside the archaeological remains.
• Your expectations matter, since the site is atmospheric and unusual, but not packed with clearly visible ruins.

Arriving at Blue Dolphin Elounda at 9:30 am

The excursion begins at the Diving Center Blue Dolphin Elounda, at the Aquila Hotel Elounda Village in Elounda, Crete. The listed start time is 9:30 am, and pickup can be arranged individually within the Elounda area.

That pickup option is useful if you are staying nearby and do not want to sort out local transport first thing in the morning. The center is also near public transportation, though the information provided does not specify routes or fares. Confirm your pickup details before the day of the outing, since the arrangement is made individually.

From the center, you are transported to the Olous site. The journey itself is not presented as a sightseeing stop, but it keeps the outing tidy and avoids making you find your own way to the water. The activity finishes back at the same meeting point.

The briefing gives the stones a story

Before entering the water, you receive an introduction to Olous and the ancient remains. This is one of the most valuable parts of the experience because the underwater structures are not self-explanatory.

The guide’s presentation covers what you may see and what to expect. That preparation helps you recognize the old road, steps, walls, temple area, kitchen, and villa mentioned during the swim. One especially strong outing included a presentation that made the later route easier to picture, from the first house to the main street and temple, then back past seagrass toward the kitchen and villa.

I would pay close attention here. The site rewards imagination, and the briefing gives you the basic framework. Without it, you might look at a few stones and wonder what you are meant to be seeing. With it, the scattered remains become clues to an ancient settlement.

The operator has independently researched the site and continues to add background information. That matters because the visible remains are limited. You are not simply floating over ruins while someone points vaguely downward. The guide tries to connect each feature with how the city may have functioned.

Getting fitted with the mask, fins, snorkel, and wetsuit

The equipment package includes a mask, snorkel, fins, and wetsuit. You do not need to arrange the main gear yourself, which keeps the cost easier to judge and makes this a practical first snorkelling experience.

Preparation can take longer than expected. One person enjoyed the outing but felt the fitting and setup took too long. That is a fair tradeoff for a small group with mixed ability, especially when the guide needs to check masks, explain the equipment, and help nervous swimmers.

The guide can teach basic snorkel technique, so you do not need to be an experienced swimmer or snorkeller. Several outings included first-time participants who struggled at first but improved with calm instruction and repeated tips. Adam, for example, was praised for his patience with a beginner, while Jackie was noted for checking comfort and offering useful guidance.

You should still expect to manage a moderate level of physical activity. The activity information asks for moderate physical fitness, and the minimum age depends on experience and weather conditions. Those details are assessed rather than stated as one fixed age rule.

Swimming over Olous at only 50 to 80 centimeters

Once you are in the water, the distinctive feature of Olous becomes clear: the remains are extremely shallow. At around 50 to 80 centimeters below the surface, you can look down without needing advanced water skills or extended underwater time.

The shallow depth makes this a good choice if you are curious about snorkelling but do not want a demanding outing. It also lets the guide stay close to the group and offer help quickly. The small maximum of eight people adds to that sense of control.

The route may include the old road, steps, sections of buildings, a temple area, and other traces of the settlement. The exact amount you see will depend on visibility, weather, and how clearly the remains show on the day. Some people find the site fascinating because they can link the stones to the presentation. Others find it less impressive than expected because so little survives in an obvious form.

That difference is important. If you want tall walls, statues, or a clearly preserved city under the sea, this is likely to disappoint. If you enjoy ancient places that ask you to reconstruct the past from fragments, Olous offers something unusual.

Fish, octopus, and starfish beside the ruins

The archaeology is the main reason to book, but the marine life adds pleasure to the swim. The experience can include many fish, both small and larger ones, as well as octopus and starfish.

This combination gives the outing a pleasant two-part character. You begin by looking for human traces, then notice the living world moving around them. Even if the ruins appear faint on the day, the fish can keep the snorkelling engaging.

The guide may point out marine life while also explaining the stonework. That gives you something to watch between archaeological features. It also keeps the outing from feeling like a dry history lecture delivered beside the water.

The setting itself is repeatedly described as beautiful, but the supplied details do not promise a particular type of water visibility or a fixed list of animals. Treat the fish and other sea life as a welcome part of the outing, not a guaranteed wildlife show.

How the guides handle first-timers

The strongest feature of this experience is the human touch. The guides are repeatedly described as friendly, attentive, and patient, especially with people who are uneasy in the water.

Dimitri calmly managed a group that included both confident snorkellers and a couple who were uncomfortable and left early. Julie was praised for guiding the group and adding useful information. Jackie was described as patient and clear, and Adam helped a first-time snorkeller improve through steady tips. A French-speaking instructor has also led an outing.

This matters because a small group does not always mean everyone has the same ability. One family may want to keep moving while another person needs time to adjust to the mask. The guide’s ability to balance those needs can shape the whole morning.

If you are nervous, tell the guide at the start. The experience is designed to suit beginners, but honest communication gives the guide a better chance to set a comfortable pace. You should not feel embarrassed about needing help with breathing through the snorkel or getting used to the mask.

What the price of $66.08 includes

At $66.08 per person, the outing is not the cheapest way to spend two hours in Elounda, but the price includes several useful elements: transport from the center to Olous, the historical introduction, a guided snorkelling session, and the full basic equipment set.

The value is strongest if you are new to snorkelling or are staying in Elounda without your own gear. You pay for guidance as well as equipment, and the historical explanation gives the site more meaning than a simple swim past shallow stones.

The small group also supports the price. With no more than eight people, you have a better chance of hearing the presentation and getting personal help than you would on a large boat outing. Pickup within Elounda adds convenience, though the exact arrangement should be confirmed before you go.

The value is weaker if you already own snorkelling equipment and mainly want a long, independent swim. It is also weaker if you expect major visible ruins. You are paying for interpretation, support, and access to an unusual shallow archaeological site, not for a grand underwater monument.

Who will enjoy Olous most

I would recommend this outing to several types of people:

• First-time snorkellers who want instruction and a calm introduction.
• Couples or families who appreciate a small group and a guide who can help different ability levels.
• History-minded visitors who enjoy piecing together an ancient place from partial remains.
• People staying in Elounda who value local pickup and included equipment.
• Confident snorkellers who also enjoy fish and a short cultural activity.

I would be more cautious if your main goal is spectacular underwater scenery. The site can be fascinating, but its appeal depends on your willingness to imagine the ancient city from limited visible remains.

Children may enjoy the shallow water and fish, but the minimum age depends on experience and weather conditions. Ask the operator before booking if a child is joining. The activity requires moderate physical fitness, so it is not suitable for every ability level.

Timing, weather, and cancellation details

Plan on roughly two hours and 30 minutes from start to finish, even though the water portion is described as lasting about two hours. The extra time allows for transport, the presentation, equipment fitting, and preparation.

Good weather is required. If poor weather forces cancellation, you are offered another date or a full refund. For any other cancellation or change, the experience is non-refundable and cannot be amended, so choose your date carefully.

Confirmation is sent within 48 hours of booking, subject to availability. The activity is offered in English, and the group limit is eight people.

Should you book the Olous snorkelling excursion?

Book it if you want a small, guided, beginner-friendly outing that combines ancient history with a gentle swim. The calm instruction, included equipment, shallow water, and chance to see fish, octopus, and starfish make it a sensible choice for a half morning in Elounda.

Do not book it expecting a fully preserved city beneath the waves. The ruins are partial, and you will need to use your imagination. That is not a flaw, but it should shape your expectations.

For me, the best reason to go is the combination of a patient guide and an unusual setting. The stones may be modest, but the idea of moving over an ancient settlement while fish pass below you is memorable. If that sounds more appealing than a standard beach snorkel, the $66.08 price is reasonable.
