What you see
The palace front from the sea — the angle it was designed for — then out past Sustipan and the Marjan cliffs, with Šolta and Brač going pink to the south. Most boats cut the engine for twenty minutes at the turn, and the silence is the point. The palace wall from the water is the thing you cannot get from the land, and it is the reason the tour exists.
If you would rather watch from land, Sustipan is the headland the boats pass, and it is free.
Choosing one
Small boats of ten to twenty people are much better than the large party catamarans, which are essentially floating bars with a soundtrack. Sailing boats are slower and better, because the silence at the turn is the best moment of the trip. Expect €40–60 with a welcome drink, and check what is included — the good ones include a glass of wine and some fruit, the cheap ones include a beer and nothing else.
For a longer evening on the water, the Šolta sunset swim cruise takes five hours, with three swim stops and an hour in Maslinica.
Practical
Two hours, departing from Matejuška or the Riva, usually at 18:30 in summer. Bring a layer — the sea breeze after sunset is cooler than you expect, even in August. Book a day ahead in season, because the small boats fill. The cruise is the best first-evening thing to do in Split, and a good last-evening one too.
Most boats leave from Matejuška or the Riva, Split's seafront promenade.
