Indonesia, with more than 1700 islands, is such a diverse, sprawling and unique country, that you can travel it for years and you'll still barely scratch the surface. You'll probably won't find a person in the world who covered it all.
Indonesia is the world's largest island country stretching mainly in Southeast Asia, with some territories in Oceania. Wherever you may be, some things won't change. Cheap and delicious food, friendly people, amazing sunrises, and sunsets. What will change, is the scenery. In Indonesia, you can easily see rainforests, jungle, cultural attractions, temples, volcanos, mountains, remote beaches, incredibly diverse marine life, and bustling cities.
Simply put, there is a place for everyone. For those, who are seeking pristine natural beauty, for those who came to enjoy nightlife and lively culture, for those, who like a mix of both, Indonesia is the right choice.
