What Do You Wear on a Sunset Cruise in Santorini?
Swimsuit under your clothes, a dark one for the hot springs, and a warm layer for the ride home. The kit that actually works on a caldera catamaran.
By Nikos Andreou, Santorini sailing writer; five summers crewing caldera catamarans out of Vlychada
There is a moment on every caldera evening when the boat turns for home, the sun is gone, and half the deck starts hunting for something with sleeves. Air off the water at blue hour is far cooler than the air you boarded in, and a wet swimsuit under a cotton dress makes it colder still. Almost nobody plans for that hour.
What do you wear on a sunset cruise in Santorini?
Swimwear under light clothes, a dry layer for dinner and something warm for the ride back. Make the swimsuit a dark one: the hot-springs water at Palea Kameni carries iron and sulfur that stain pale fabric permanently. Add flat deck shoes or bare feet, sunglasses, and a wind layer you can actually get to.
The boat is not a restaurant with a cloakroom. Whatever you carry on stays in a bag at your feet, so the answer is layers you can add and shed without a changing room.
| Moment | What works | Where people go wrong |
|---|---|---|
| Pickup and boarding | swimsuit on under a light dress, or shorts and a tee | an outfit needing somewhere private to change |
| The swim stops | the dark swimsuit, hair tied back | pale swimwear that never recovers |
| The hot springs | the same dark suit, plus a 30 to 50 metre swim | expecting a jetty rather than a swim |
| Dinner on deck | a dry layer over the suit | eating in a soaked swimsuit, cooling early |
| Sunset | a light long sleeve on | the warm layer left in the bag |
| The ride home | fleece, hoodie or wind shell, dry hair | a wet cotton dress in the apparent wind |
Sunscreen belongs on the list too. Half the trip is full afternoon sun on an open deck, white surfaces throwing light back at you.
Why does the hot spring decide your swimsuit?
Because the water at Palea Kameni is warm, mineral-heavy and permanently unkind to light fabric. The iron and sulfur in the springs leave a rust tint on white, cream and pastel swimwear that no wash removes. The pool sits at 30 to 35 C against a sea of 20 to 25 C.
Wear black, navy, dark green, anything you would not mourn. Crews say it at every briefing and somebody still finds out the hard way.
One more detail before you pack: the springs are reached by an open-water swim of 30 to 50 metres, with no ladder into the cove and no shallow entry. If that is not for you, bring a book and a hat instead. The big shared catamaran includes the springs among its swim stops, and you can see dates and the live price on its listing. The stop is covered in the volcano and hot-springs side of the caldera.
What do you actually need for the ride home?
One warm layer, and it should be dry. The boat runs back to the marina after dark, adding the apparent wind of its own movement to whatever is left of the day's breeze. A fleece or a light wind shell covers it. In July and August a thin long sleeve is usually enough; in April and October, take the fleece.
The meltemi blows from June to September, strongest in July and August, typically 4 to 7 Beaufort. It builds through the middle of the day and eases toward evening, which is why the sail home is usually the calmest hour. Calm is not the same as warm. Five summers crewing out of Vlychada and the sight of shivering passengers wrapped in boat towels at 22:00 never stopped being routine. If you burn easily, a long-sleeved swim shirt solves the afternoon too.
Do the dinner boats expect you to dress up?
The listings do not set out a dress code, and none of these boats is a restaurant. What they describe is an open deck, a BBQ or mezedes dinner and an open bar, so the sensible standard is smart-casual that survives salt and wind. Where the evening does make demands is the walk to the pier.
| Cruise | Getting aboard | On the table | Dress note |
|---|---|---|---|
| BBQ Sunset Catamaran | pickup included | BBQ, white wine, beer, soft drinks | swim stops and hot springs, pack around water |
| Caldera Classic Catamaran | pickup included | BBQ meal, dry white wine | swim-first, dark suit essential |
| Luxury Day-or-Sunset Catamaran | pickup, max 20 | Greek meal, open bar with a cocktail | quieter deck, room to change layers |
| Lagoon 560 Luxury Sunset | transfer included, Vlychada | Greek BBQ aboard, wine and beer | big stable deck, flat drive to the marina |
| Luxury Sunset Dinner Cruise | minibus pickup, Ammoudi | mezedes, BBQ, dessert, open bar | dinner-first, dress a step up if you like |
| Romantic Sunset Catamaran | transfer optional, Ammoudi | appetizers, BBQ, wine, ouzo, beer | 16 guests, the Ammoudi approach if you skip it |
| Private Wind Spirit Sunset | pickup, Vlychada Marina | Greek dinner, wine, beer, soft drinks | private deck, expectations are yours |
Ammoudi is the variable. The bay sits roughly 300 steps below Oia at the end of a switchback road, and 2026 civil-protection rules limit general vehicle access to it. Take the included transfer where there is one, and treat heels as a bad idea on that side of the island.
What about your feet, and what should stay at the hotel?
Bare feet or flat soft-soled shoes. Crews ask for hard shoes off anyway, because black soles mark a white deck and heels punish teak. Leave the wheeled bag, the hard suitcase and anything you would hate to watch slide across a cockpit at ten degrees of heel.
A small soft bag holds the rest: a towel if the boat does not supply one, the dry layer, sunscreen, a hat with a cord, a waterproof phone case and a bag for the wet suit. Motion-sickness tablets go in too if you are prone, taken before boarding rather than when the horizon starts moving.
For the most table and the least swimming, dinner-first sails compared sets out what the meal buys, the dinner and romance boats sit together on the homepage, and the evening's timing month by month tells you how late you get home. You can check availability on the Ammoudi dinner boat.
Common questions
What do you wear on a sunset cruise in Santorini?
Swimwear under light clothes, a dry layer for dinner and something warm for the ride home. Choose a dark swimsuit, because iron and sulfur at the Palea Kameni hot springs permanently stain pale fabric. Flat deck shoes or bare feet, sunglasses, a hat and sunscreen finish the list.
Do I need a dark swimsuit for the Santorini hot springs?
Yes, if you plan to get in. The water at Palea Kameni carries iron and sulfur that leave a rust tint on white and pastel swimwear which will not wash out. The pool sits at 30 to 35 C against a 20 to 25 C sea, reached by a 30 to 50 metre swim.
Should I bring a jacket on a santorini sunset cruise?
Bring one warm dry layer. The boat returns after dark, adding its own apparent wind to whatever breeze is left, and a wet swimsuit under cotton makes it colder. A thin long sleeve covers July and August. In April, May, September and October, take a fleece.
What shoes should I wear on a catamaran?
Flat, soft-soled and easy to remove, or nothing at all. Hard black soles mark white decks and heels damage teak, so crews ask for shoes off at the gate. If your boat leaves Ammoudi Bay, the harbour sits roughly 300 steps below Oia at the end of a switchback road.
Is there a dress code on a Santorini dinner cruise?
None of the seven listings sets one out. The dinner boats out of Ammoudi serve mezedes, BBQ, dessert and a full open bar on an open deck, so smart-casual that copes with salt and wind is right. Nobody is turned away for shorts and a tee.
