Things to do in Rethymno is one of those rare towns that feels like it belongs to a different century. Narrow cobblestone lanes wind between Venetian mansions and Ottoman fountains, the old lighthouse watches over a harbor that has welcomed sailors for centuries, and just beyond the shoreline, the Cretan Sea stretches out in a palette of blues that no camera can fully capture.
Most visitors spend their days wandering the old town, sampling local food, and lounging on the long sandy beach. All of it is worth your time. But if you’re looking for the best things to do in Rethymno that go beyond the obvious, the answer begins at the harbor — and ends somewhere spectacular out on the water.
NaviBlue Cruises invites you to discover Rethymno from an angle most travelers never consider: the sea.

Why the Water Is Where Rethymno Truly Shines
The town’s relationship with the sea is ancient and inseparable. For centuries, its harbor was a trading hub connecting Crete to the wider Mediterranean world. Today, that same harbor is where NaviBlue Cruises launches daily — and where the real adventure starts.
From the deck of a boat, Rethymno looks entirely different. The skyline of minarets and fortress walls shrinks into the distance as the coastline opens up into something wilder and more elemental: volcanic rock formations, arched sea caves, and coves where the water turns a luminous turquoise that stops you mid-sentence. This is the Crete that postcards try to capture and never quite manage.
A boat tour with NaviBlue isn’t just a scenic ride — it’s a complete shift in perspective.
Exciting Boat Tours Around Rethymno
For travelers who enjoy shared experiences and a social atmosphere, NaviBlue’s group boat tours are a fantastic way to spend a day on the water. You’ll join a small group of like-minded explorers, guided by a knowledgeable local captain who reads the sea and the wind and steers you toward the most rewarding spots.
Typical routes head east or west along the coastline, stopping at beaches and coves that are either difficult or impossible to reach by land. Time is built in for swimming, snorkeling, and simply floating in water so clear you can count the pebbles six meters below. A freshly prepared meal on deck, eaten with salt on your skin and the smell of the Aegean in the air, is something you’ll remember long after the tan has faded.
The boat tours are also an ideal choice for solo travelers or couples who want to meet people from around the world in a relaxed, open setting.
A Private Cruise Experience Like No Other
For those who prefer their own pace and complete flexibility, NaviBlue Cruises offers private cruise experiences that can be shaped entirely around your wishes. Want to spend three hours anchored in one perfect bay? Done. Prefer to cover more ground and tick off five different swimming spots in a day? Also possible.
Private cruises are particularly popular with families — children love the freedom of jumping off the boat, snorkeling over rocky reefs, and spotting the occasional octopus or sea turtle. They’re equally beloved by couples celebrating a special occasion, groups of friends marking a milestone, or simply anyone who wants the rare luxury of feeling like the sea belongs to them for a few hours.
Your captain brings local knowledge that no guidebook can replicate: the exact cove where bioluminescent plankton gathers on summer evenings, the stretch of cliff where falcons nest in spring, the underwater rock formation that snorkelers have been quietly passing on by word of mouth for years.
Adding NaviBlue to Your Rethymno Itinerary
Rethymno rewards slow travel, and a boat tour with NaviBlue fits naturally into a few days of thoughtful exploring. Consider pairing your cruise with an evening stroll through the Venetian Harbor, a visit to the impressive Fortezza fortress that dominates the headland above town, or a long lunch at one of the seafood tavernas lining the old port.
Half-day departures leave time to explore the town in the morning before heading out on the water in the afternoon — arriving back at the harbor just as the light turns golden and the outdoor tables begin to fill. Full-day cruises make a magnificent centerpiece for a day when you want to be nowhere else but the open sea.
Bookings can be arranged directly through the NaviBlue website, and the team is happy to help tailor any experience to your specific group, schedule, or celebration.
Make the Sea Part of Your Story
Rethymno has been welcoming travelers for centuries, and the best visitors are the ones who let themselves be surprised by it. The old town is beautiful, the food is exceptional, and the history runs deep — but the Cretan Sea, experienced from the deck of a NaviBlue boat, is something in a category entirely its own.
Whether you choose an exhilarating group tour or a peaceful private cruise, NaviBlue Cruises delivers the kind of experience that becomes the story you tell when people ask about your trip to Crete.
