When strolling around, in particularly around the market place, you'll see a certain number of stands offering "souvenirs from Trogir". More or less, it is trash coming out from distant countries.
In the old core of the town you'll find, however, nice souvenir shops among which Katarina is the best. Here you can find genuine souvenirs from Trogir made by the local craftsmen. This souvenirs cost you more but you'll buy yourself a piece which will always remember you on good times you had in Trogir.
In this little house, you can find many souvenires and jewlery. It is situated on the sea side of the town, on the south exit. I like this place so much and everytime I'm there I stop to buy something new.
Walking through the main entrance of the city walls in Trogir, you can find many local painters and artists selling their products. Paintings are really beautiful and not very expencive, mostly showing Trogir or some sea theme. It's always crowded, but it's worth a little waiting in line.
In the centre of Trogir there are many little streets with shops and restaurant. You can find some nice souvenirs in those shops.
Both within the walls of trogir and before you cross the bridge onto the island there are a number of market stalls. worth a look for some local crafts, oddities and food and drink.
