Heraklion: Dia Island Sailing Cruise with Snorkeling

If you’re after a relaxing day on the water combined with some of Crete’s most stunning scenery, this Dia Island sailing cruise from Heraklion might just be your perfect day out. While we haven’t tried it ourselves, plenty of travelers seem to be quite impressed, especially with the knowledgeable crew, the crystal-clear waters, and the delicious food onboard.

What really stands out is the chance to explore an untouched island environment—completely uninhabited, which means you’ll get a genuine sense of nature unspoiled by crowds.

This experience is ideal if you’re looking for a well-rounded day of sailing, scenic views, and authentic Greek hospitality. It’s especially great for travelers who want a comfortable, small-group setting, with plenty of opportunities to swim and relax.

What to Expect on the Cruise

Starting Point and Departure

The adventure kicks off from Heraklion’s Old Venetian harbor, where you’ll meet your crew outside Café Marina. This historic setting offers a nice backdrop and a chance to admire the Venetian fortress before setting sail. Transfers from central Heraklion are not included, so if you’re staying in the city center, you’ll need to get there on your own.

Sailing to Dia Island

Once onboard, the boat glides out into the Mediterranean, with scenic views of the harbor and a chance to see the historic fortress from the water. The trip to Dia usually takes between 1 hour and 10-20 minutes, depending on weather conditions. The sailing itself is part of the experience, and many reviews note the crew’s skill at harnessing the wind—adding a touch of authentic sailing charm.

The Island Stop

Arriving at Dia Island, you’ll find a truly peaceful and unspoiled environment. The island’s waters are famously clear, a perfect setting for swimming or snorkeling. The crew provides snorkeling gear, and the reviews highlight how many guests enjoyed exploring the sea floor, often spotting fish and even ancient pottery.

One reviewer described the island as “breathtaking,” with plenty of room for paddleboarding and relaxing in the calm waters. Plus, the fact that it’s uninhabited means no crowds—just you, the sea, and nature.

The Highlights and Why They Matter

The Unspoiled Dia Island

Many reviews highlight the island’s untouched beauty. It’s a rare chance to enjoy a quiet bay, snorkel around ancient pottery, and take photos of dramatic cliffs and mountain backdrops. The peace and natural beauty make it a highlight for many.

The Crew and Guides

Guests frequently mention how much they appreciated the crew’s professionalism and friendliness. One reviewer noted, “the captain was absolutely amazing with all the myths and history of Crete and Dia Island,” which adds an educational touch that makes the trip more engaging.

Food and Drinks

The onboard meals and drinks receive high praise; they’re seen as offering good value for the cost. The seafood pasta, Greek salad, and local wine are often described as tasty and plentiful, which can be a big plus on a full-day cruise.

Flexibility and Value

The tour’s options for half or full-day trips, along with small group sizes (max 18 people), make it feel intimate and personalized. The inclusion of snorkeling gear, paddleboards, and safety equipment means you’re well cared for without additional costs.

Potential Drawbacks or Considerations

While many reviews are glowing, it’s worth noting that weather conditions significantly influence the experience. If the sea gets choppy, the crew might skip visiting a second bay or adjust the schedule, which can be disappointing if you were hoping for multiple swimming spots.

Plus, the trip duration can be quite long—up to 7 hours—so if you’re not comfortable on the water or prefer shorter excursions, this might feel a bit overwhelming. Also, transfers from central Heraklion aren’t included, so you’ll need to plan accordingly.

Finally, the tour isn’t suitable for wheelchair users, which is common for sailing trips, but it’s good to keep in mind if you or travel companions have mobility issues.

Who Is This Tour Best For?

This cruise is ideal if you’re seeking a relaxed sailing experience with plenty of opportunities to swim, snorkel, and enjoy authentic Greek cuisine. It suits travelers who enjoy small-group settings, want to explore a peaceful island environment, and are comfortable spending several hours on the water.

It’s a good fit for active travelers who like trying paddleboarding or snorkeling, and for those who appreciate the company of friendly, knowledgeable guides. If you’re traveling with friends or a small family looking for a memorable day out, this tour ticks many boxes.

However, if you’re looking for a quick, short trip or traveling with mobility restrictions, you might want to consider alternative options.
