Olous Snorkeling: Sunken Minoan City with Guide

Swim above Minoan ruins and learn their history from the water

This guided snorkeling trip takes you to Olous, a sunken Minoan city off the coast of Crete, where ruins lie shallow enough to explore without scuba certification. A professional snorkel guide leads you through the site, explains its history, and teaches snorkeling technique as you move through the remains. The excursion includes a presentation on Olous before you enter the water, all snorkeling gear, and transport from the diving center in Elounda.

The experience

The ruins of Olous sit 50 to 80 centimeters below the surface: deep enough to feel submerged, shallow enough that you can explore them on breath-held snorkeling alone. Blue Dolphin Diving Center has been running organized trips to this site for over five years, and it's the only outfit offering regular access to it. Before you get in the water, the guide walks you through a presentation on Minoan history and what you're about to see, so the stones and structures make sense when you're looking at them from below.

Once in the water, a professional guide leads you through the site at a pace that lets you take it in. The guide can teach you snorkeling technique as you go (how to breathe, how to move, how to stay comfortable), so even if you're new to it, you're learning in real time. The shallow depth means you're never far from air, and the quiet of the site itself is part of what makes it work: no crowds, no noise, just the sound of your own breathing and the shape of an ancient city below you.

The trip runs about two and a half hours total, including the presentation and the time in the water. You get fins, mask, snorkel and a wetsuit. Transport leaves from the diving center in Elounda and brings you back there when you're done. The guide speaks English, Spanish, French, German and one additional language, so if your group has a language preference, mention it when you book.

What exactly am I looking at when I snorkel Olous?

Olous was one of the most important cities in Minoan history, and its ruins (walls, structures, and archaeological remains) lie on the seafloor at 50 to 80 centimeters deep. The shallow depth keeps the site accessible to snorkelers while the water clarity lets you see the detail of what's there. The guide explains what each part of the site was and how it fits into Minoan civilization.

No. Olous is designed for snorkeling, not scuba diving. The ruins sit shallow enough that you can explore them on the surface, holding your breath and diving down for short periods: no certification needed, and no heavy equipment required.
