Komarna is well placed for day trips along the coast and into Herzegovina.
Neretva River Safari — From the village of Vid, 25 km north, you can take a ride on traditional flat-bottomed boats (trupica or lađa) through the Neretva delta wetlands. Most trips include a tasting of local specialities: frogs, eels, dried figs, and homemade grappa.
Ston — Half an hour south. The 5.5 km of medieval walls are the second longest in Europe after the Great Wall. Ston is also famous for its oysters — eat them fresh at the waterfront.
Dubrovnik — An hour's drive south. The walled old town needs no introduction.
Mostar — 65 km inland in Bosnia-Herzegovina. The UNESCO-listed Old Bridge and the Ottoman old town are the highlights. Try ćevapčići while you are there.
