What are the best day trips from Split?

Trogir over Hvar if you only have one day and one of you tires of boat transfers. Bus #37 leaves from Split's local bus station every 20 minutes. It costs about 3 EUR and drops you at Trogir's gate in 30 minutes. The old town sits on a tiny island connected by a short stone bridge. Three hours covers it. Trogir Cathedral, started in 1213, has a Romanesque portal by Master Radovan that's worth 15 minutes even for the partner who thinks they don't like churches. Kamerlengo Castle, built in 1420 by the Venetians, has open-air ramparts where the afternoon heat eases into a salt breeze off the channel. Grab the 6pm bus back, shower, and eat in Split. Trying to find a good dinner along Trogir's tourist-facing waterfront is the mistake couples make. The restaurants there tend to smell like the same reheated squid.

For the island day, pick Hvar if one of you wants wine and the other wants a swim. The Krilo catamaran from Split's waterside terminal reaches Hvar Town in roughly 60 minutes. About 12 EUR one way. Get the 9am sailing and you'll land before cruise-ship passengers arrive around 11am. Walk up to the Fortica fortress. It's 20 minutes of steep steps. The view across the Pakleni Islands is the kind of thing that settles the argument about whether the early alarm was worth it. Wine bars in town pour local Plavac Mali for 15 to 25 EUR per tasting. If the beach-lover half wins the morning vote, take the catamaran to Bol on Brač instead, about 50 minutes. Zlatni Rat beach shifts shape with the current, which sounds like a brochure line but you can see it change hour to hour. The pebbles are smooth and warm underfoot by 10am in mid-August. Catch the last catamaran back around 5:30pm or you're sleeping on the island.

Krka National Park sits 83 km north and needs an early start. Leave Split by 8am. The bus to Skradin takes about 75 minutes, roughly 8 EUR. From Skradin, a 25-minute boat ride drops you at Skradinski Buk, where 17 travertine waterfalls step down through green pools. Swimming has been banned since 2021 to protect the travertine. Bring the camera, not the towel. The boardwalk loop takes about 2 hours, and the spray from the falls cools the air by a few degrees even when Split is hitting 33°C. The walkways fill with tour groups by noon. For the couple where one wants adrenaline and the other wants a quiet lunch by the water, Omiš is the better pick. It's 25 km southeast, a 30-minute bus ride. The Cetina River canyon offers half-day rafting trips for about 35 to 45 EUR per person, while the non-rafter eats grilled brancin at a waterfront konoba in the old town. You meet back up by 3pm.

Salona was the Roman capital of Dalmatia before Split existed. It's the quick-hit morning trip for the history half. Bus #1 from Split reaches Solin in 15 minutes for under 2 EUR. The ruins spread across open fields with almost no shade, so start early. The amphitheater held an estimated 18,000 spectators. You can still walk its stone tiers, feeling heat radiate off limestone that's been baking since the 3rd century. The Hollow Church, dating to around 1100, sits at the eastern edge of the cemetery area. Two hours covers everything. The partner who wants the pool or the beach after lunch gets it, while the other got Roman ruins at breakfast. You can combine Salona with Trogir in a single day. Bus #1 back to Split, transfer to #37, and you're eating lunch in Trogir by noon.
