Croatia is home to over 1,000 islands. Most are only accessible via boat. Which makes it a perfect place for UberBoat. This add-on to the ride-sharing service lets you summon a vessel and captain on-demand, day or night, from Split, the Split airport, Hvar, or Dubrovnik. The service begins June 26 and runs through the summer, and options are available for groups up to 8 or 12, with half- and all-day rentals also available.
