Split's sights sit inside a working Roman palace, so most of them are a five-minute walk apart. Start with Diocletian's Palace and the cathedral bell tower, then climb Marjan for the view that makes sense of the whole city.
The nine-until-midnight part of a Split night, and the best of it. Small cellars and side rooms inside Diocletian's Palace pour Dalmatian wine by the glass with no music you have to shout over. Arrive before nine if you want a table, and leave around midnight when the lanes empty.
The open-air produce market against the palace's eastern wall, running every morning since forever. Figs, tomatoes, olive oil, cheese from Pag, and old women who will tell you your peaches are not ripe yet. Free to walk through, best before nine.
The layer between the Riva and the clubs: small cocktail rooms, jazz corners, hostel bars and neighbourhood cafés that turn into bars after nine. This is where the local crowd drinks, it costs about a third less than the seafront, and it is the part of Split nightlife that still works in February.
