Traveling outside the city or outside the island is usually better to take a plane or train. The goal is to save time and effort. But, some people prefer to take a car. Besides being more flexible, riding a car when traveling between cities or islands can provide an unusual experience.
Besides Java, Sumatra is the most exciting place to explore using a private car. If you are from Java, your journey will begin with crossing the Sunda Strait and anchoring in Bakaheuni Harbor, Lampung, South Sumatra.
