Will I Get Seasick? An Honest Guide to Our Boat Tours

26 August 2026 · 6 min read

A flat calm sea on the Blue Cave route, the glassy morning conditions locals call bonaca

Some of our tours are gentle and one is genuinely rough, and we would rather tell you which is which before you book. This is the page we send worried guests: the honest sea state of every tour, and what actually helps on the day.

Key takeaways

  • The Three Island Tour is the gentlest option: a large, slow traditional wooden boat that rarely leaves sight of land.
  • The Blue Lagoon half day stays in the sheltered archipelago on short hops, with most of the five hours spent anchored or ashore.
  • The Blue Cave tour is the rough one: ten hours on a fast boat with one long open-water crossing to Biševo.
  • Morning departures are usually calmer, because the maestral sea breeze builds through the afternoon and makes later crossings livelier.
  • Krka is mostly a day on land with only a 30-minute river boat ride, the choice if any sea motion worries you.

Honest answer: on most of our tours, probably not, and on one of them, maybe. This is the page we send guests who write to us worried about seasickness, so there is no sales voice in it. Below is what each tour actually feels like on the water, which one to pick if you know you are prone, and what genuinely helps on the day.

The short answer, tour by tour

Three Island Tour: the gentlest day we run

If seasickness is your main worry, start here. The Three Island Tour runs on a large traditional wooden boat, takes its seven and a half hours without rushing, and rarely leaves sight of land. The day is built around anchored swims at the Blue Lagoon and Duga Bay and free time ashore in Maslinica, so for much of it the boat is not moving at all. It is also the boat with the most room to move around, a shaded lounge and a proper toilet, which matters more than people admit when they feel queasy. You leave at 09:00 and are back by around 16:30.

Blue Lagoon half day: short hops in sheltered water

The Blue Lagoon half day stays inside the sheltered archipelago between Drvenik, Šolta and Čiovo, moving in short hops rather than long crossings, and most of the five hours is spent anchored in the lagoon or ashore in Maslinica rather than under way. You are in the water within about half an hour of leaving the Riva. It is a speedboat, so you feel the sea more than on the big wooden boat, but there is no open-water crossing anywhere on the route. Sea state is still weather-dependent, and your skipper makes the final call.

Blue Cave: the rough one, and we tell you so

The Blue Cave tour is the roughest thing we sell, and the tour page says exactly that. It is ten hours on a fast boat with one long open-water crossing to Biševo, about 36.6 nautical miles from Trogir and the longest single leg of the day. That is why it is not recommended for children under 8, pregnant women or anyone with back problems, and why we are blunt with guests who have severe motion sickness: a sick guest has a miserable day. One thing in your favour is the timing. The early 06:30 start means the long crossing out to Biševo happens in the morning calm, and it is the ride home in the afternoon, once the maestral has built, that is usually the livelier leg. If you are prone but determined, the day is manageable with the preparation below. If you are on the fence, take the lagoon or the wooden boat and enjoy your holiday instead.

Krka: the no-swell option

The Krka Waterfalls day is mostly not a boat trip. It is about an hour and a half by road from Trogir, a self-guided walk through the park at your own pace, and the only boat involved is the scenic 30-minute ride down the river to Skradin. If any sea motion at all is a problem for someone in your group, this is the day out that removes the question entirely.

What actually helps

If it starts anyway

Do not go inside the cabin, however tempting the shade looks; an enclosed space with no horizon is the fastest way to make it worse. Stay in the open air, keep your eyes on the islands rather than on a screen, and tell the skipper rather than suffering quietly. Crews on this coast have seen seasickness every season of their working lives, nobody will make a thing of it, and a small change like slowing through a chop or pointing you to a steadier seat often does more than any tablet. Most people feel fine again within minutes of the boat anchoring, and the gentler tours spend most of their day anchored or ashore rather than under way.

The weather call is made for you

The days that would genuinely test your stomach mostly never happen, because the skipper cancels them. A strong bura, the cold north-easterly that turns the channel to whitecaps, cancels a tour outright, and you are told before you board, with a full refund or another day. The normal afternoon maestral does not cancel anything; it just means a livelier ride home. How that decision gets made is worth two minutes of your time: our guide to the bura and the maestral explains it properly.

Still unsure? Write to us and describe the worry honestly, and we will point you at the right tour, or talk you out of the wrong one. For the rest of the practical questions, seating, shade and where the toilet is, see what to expect on board.

Frequently asked questions

Will I get seasick on a boat tour from Trogir?
On most of our tours, probably not; the Blue Cave tour is the only genuinely rough day. The Three Island Tour and the Blue Lagoon half day stay close to land in sheltered water, and Krka involves only a 30-minute river boat.
Which Trogir boat tour is best if I get seasick?
The Three Island Tour: a large, slow traditional wooden boat that rarely leaves sight of land. Much of the day is spent anchored at swim stops or ashore in Maslinica, and there is shade, space and a proper toilet on board.
Is the Blue Cave tour rough?
Yes, it is the roughest of our tours, with a long open-water crossing to Biševo at speed. That is why it is not recommended for children under 8, pregnant women or anyone with back problems.
What helps with seasickness on a speedboat?
Take a remedy before departure, sit towards the middle of the boat and stay outside in the air. A morning departure also helps, because the maestral breeze builds through the afternoon and makes later crossings livelier.
Are morning or afternoon boat departures calmer?
Morning departures are usually calmer, because the maestral sea breeze builds through the afternoon. It is normal sailing weather, not a danger, but it makes an afternoon ride livelier if you are prone.
