Transport in Croatia relies on several main modes, including transport by road, rail, water and air.
 Road transport incorporates a comprehensive network of state, county and local routes augmented by a network of highways for long-distance travelling.
 Water transport can be divided into sea, based on the ports of Rijeka, Ploče, Split and Zadar, and river transport, based on Sava, Danube and, to a lesser extent, Drava.
 Croatia has 68 airports, nine of which are international.
 The country also has several airlines, of which the most notable is Croatia Airlines.
 Rail transport is fairly developed, with dual track and electrification not very common, although high-speed tilting trains are used on some routes.
 However, bus still tends to be more common than rail as a mode of inter-city transport.
A continent pass (usually called something like Europe (air)pass, Pacific (air)pass or American (air)pass) is a product and service of an airline alliance.
 For a relatively low price the traveler can travel freely using all intra-continental flights the airline alliance offers on that continent.
 There are restrictions on the number of miles, flights or stops the traveler can make.
 Travelers can benefit from the extensive networks airline alliances offer and can earn reward points for each mile they fly by participating in the alliance's frequent flyer program.
A round-the-world ticket (also known as round-the-world fare or RTW ticket in short) is a product that enables travellers to fly around the world for a relatively low price.
 RTW tickets have existed for some time and in the past were generally offered through marketing agreements between airlines on several continents.
 Now, they are almost universally offered by airline alliances such as SkyTeam, Star Alliance and Oneworld, or else by specialist travel agencies that will spend time helping customize a trip to the consumer's needs.
 Prices vary but are generally in the range of 3000–5000 USD for an economy-class ticket.
 Sometimes, depending on airline and stops, it can be as low as 1171 GBP (~ 1829.57 USD).
 An alternative for a round-the-world ticket is a continent pass.
