Rhodes changes when you’re on deck. This St Marina Bay swim stop and Symi’s colorful harbor streets turn a simple day trip into a full day out on the water. The only real catch is the water break is short, so if you’re hoping for a long snorkel session, you’ll want to plan around that.

I like that the whole thing is built as a round-trip from Rhodes Harbour, so you don’t spend your day figuring out ferries or timing connections. It’s also good value for the time you get: a full morning sail, a 30-minute swim/snorkel window, and about 3 hours on Symi to walk, snack, and shop at a relaxed pace.

Quick highlights

• St Marina Bay swim and snorkel for about 30 minutes in boat-reachable water
• 3 hours free time in Symi to explore the harbor and colorful lanes
• Open sundeck plus an air-conditioned indoor area (helpful if the breeze is cool)
• Floats, onboard toilets, and WiFi for a more comfortable ride
• Colorful neo-classical houses and classic fishermen boats along the route
• A round-trip that starts and ends at Rhodes Harbour for easy planning

Rhodes to Symi by boat: what you’re really buying for $47

For $47 per person, you’re not just paying to “get somewhere.” You’re paying for a day that combines three different moods: sea views from Rhodes, a real swim/snorkel stop, and then a few hours on Symi to actually feel like you escaped the main island.

The route is straightforward: you’ll leave in the morning, sail toward St Marina Bay, stop for a swim/snorkel, then head to Symi Harbor where you get free time before returning to Rhodes Harbor later in the evening. That order matters. You get the best water time early enough that the day still feels fresh, and you arrive in Symi with enough daylight to wander without racing.

One practical note: this cruise is described as a standard boat city cruise rather than a high-speed catamaran. That means the ride can feel a bit longer than some faster options, but the trade-off is you don’t rush the day. If your goal is swimming and soaking up the harbor views, the slower pace can actually feel kinder.

St Marina Bay swim and snorkel: short stop, big payoff

St Marina Bay is the reason this trip is worth it. It’s a spot you can’t reach the same way as a normal beach, so the cruise does the legwork for you by getting you right where the water looks inviting.

You’ll get a 30-minute break with time for:

• Swimming
• Snorkeling
• Photos and a quick reset before the next sail

The cruise includes floats onboard, and you’re also advised to bring snorkeling gear plus a towel and beachwear. I’d treat the swim stop like a “grab your window” moment. Thirty minutes goes quickly, especially if you’re moving in and out with phones, cameras, and group timing.

A small consideration: the snorkel stop is often handled with boundaries, and you may be told not to go too far from the boat. Some people find the snorkeling visuals limited by that rule, but the water time is still a standout break from the usual Greece island day-trip pattern. If you’re the type who wants to snorkel for an hour straight, this won’t be that cruise.

The gear tip you’ll be glad you packed

Bring a waterproof pouch or small dry bag for your phone and keys. There’s no mention of lockers, and at least one person specifically wished for a better way to store essentials during the swim. Keep it simple: put valuables in something you can trust, then enjoy the water without doing mental math the whole time.

Symi Harbor free time: where the color and walking happen

Once you reach Symi, you’ll disembark and get about 3 hours to explore at your own pace. This is the part you’ll remember most for the look of the island.

Symi is known for its colorful neo-classical houses stacked along the harbor, and the cruise timing usually gives you good light for photos and for just standing there a minute longer than you planned. On the water ride, you’ll also pass fishermen boats, which helps sell the idea that you’re not just “touring Greece,” you’re visiting a working coastal place.

With 3 hours, you can do a loop:

• Walk the harbor and take in the main views
• Pop into shops for small souvenirs
• Stop for lunch if you want sit-down time (food isn’t included, so you pay there)
• Wander back through lanes for photo spots

The time is well-measured for casual exploring. People who want to shop, eat something, and get a feel for Symi usually feel like 3 hours lands right in the sweet spot. If you have a longer checklist, adjust expectations.

If Panormitis is on your list

One highlight mentioned with Symi is the Orthodox Monastery of Panormitis. The monastery can be a priority for some visitors, but with only about 3 hours on the island, you may find the timing tight for a long detour. If your dream is monastery-focused, consider planning extra time elsewhere rather than depending on this excursion alone.

Photo stops and the route views: why the sail is part of the show

This trip isn’t only “two destinations.” There are photo stops along the way, and the sea route itself is part of what you paid for.

From the water, you’ll get a different perspective on Rhodes, and you’re also likely to see the coast line change as you sail. That matters because Rhodes can feel busy from land, while the water gives you space to slow down and actually look. You’ll also see the classic harbor working boats as you move along, which adds authenticity without needing a scripted history lesson.

If you’re traveling with a phone camera, treat the sail like your first chance to collect your best shots. People tend to focus all their energy once they reach Symi, but the views from the boat are a big part of the charm.

Inside the boat: seating, shade, toilets, WiFi, and the stuff you’ll use

This is a comfortable day-cruise setup for the price range. Here’s what stands out based on what’s included and what passengers have noticed:

• Open sundeck with sunbeds (great on a calm morning)
• Air-conditioned indoor area (a lifesaver if the wind cools you down)
• Plenty of seating
• Toilets onboard (always a win on a day outing)
• Floats for the swim/snorkel stop
• WiFi onboard
• Insurance included in the excursion

One note about the comfort: shade can feel cold on the way back if you’re sitting in the cooler area for a long stretch. I’d bring a light layer even if the morning is sunny. The tour info also flags that during beginning and end of season, a light jacket helps.

There’s also typically a bar onboard with drinks and snacks available for purchase. So you can stay relaxed, buy something warm or sweet if you want, and avoid the “I forgot cash” panic—though cash is listed as something to bring, so don’t count on your phone only.

Timing and where to sit: a small strategy for a better day

This outing runs about 8 hours, which is long enough to need breaks, but short enough that you won’t feel stuck all day.

A timing strategy helps:

• On the outbound sail, aim for outdoor deck time if the weather is good.
• When it’s cooler, use the air-conditioned area without guilt.
• For the return, be aware that the shade side can feel chilly even when you’re still in daylight.

Also, plan your movement with the schedule in mind. The day is built around a single swim stop and then Symi time. If you miss the boarding moment or are slow to get moving at Symi, you’ll feel it because you don’t have extra buffer hours.

When to show up

You’re asked to arrive about 20 minutes before the activity starts, and check-in is expected between 8:00 and 8:30. You’ll exchange your voucher at a desk in front of the boat for entry. If you’re using pickup, it’s optional and the transfer staff will wait no longer than 2 minutes after the scheduled pickup time, though traffic can shift things up to about 15 minutes.

That’s all very workable. Just don’t assume you can stroll in last minute and still be first on board.

Who this trip is best for (and who should consider something else)

This excursion fits best if you want a balanced day: sea views, a swim you can’t easily DIY, and a few hours in a pretty port town.

You’ll probably love it if you:

• Want a real water stop at St Marina Bay rather than only time on land
• Prefer wandering and shopping in Symi instead of a long guided lecture
• Like the idea of free time rather than being locked into a strict schedule
• Appreciate onboard comfort like toilets and an indoor area

You might want a different option if you:

• Need long snorkeling time (the water window is about 30 minutes)
• Want to do a major site detour like Panormitis without feeling rushed
• Hate the idea of a slower boat ride compared with faster catamaran-style excursions

In other words, this is a solid “great day, not a full research project” cruise.

Should you book this Rhodes Harbour to Symi and St Marina Bay cruise?

If you want an easy, good-value day where swimming is part of the plan, I think this one is a smart booking. The strongest reasons are the St Marina Bay swim/snorkel stop and the 3 hours in Symi—that combination is exactly what turns the day from a bus-and-walk sightseeing routine into an actual experience.

Book it if your priority is:

• A convenient round-trip from Rhodes
• A comfortable boat ride with the basics covered (toilets, indoor space, WiFi)
• Colorful Symi streets and harbor views with time to enjoy them

Skip it if your main goal is extended snorkeling or a monastery-heavy itinerary. For those, you’ll likely want either a longer Symi stay or a different cruise structure.

Bottom line: for $47 and a full 8-hour outing, this is one of the better ways to get the water, the town, and the views all in the same day.
