Meet up with your guide and group in central Split or Trogir, then find a seat in an air-conditioned tour vehicle for the ride to Omis, on the banks of the Cetina River.
Get an orientation and all your gear, then jump in the raft and get going. Float and paddle through river cuts, past waterfalls, over rapids, and through the verdant woods. Make a stop for swimming in the crystal clear river to cool off.
End up at the town of Radmanove Mlinice after 4 miles (12 km) and return to your starting point via tour vehicle.
