Acountry made up of more than 17,000 islands forming a 3,200-mile-wide archipelago, Indonesia is both massive and incredibly diverse. From the metropolis of Jakarta to the jungle of Borneo, Indonesia really has it all. Its geography and infrastructure can make it a somewhat challenging place to travel, though, so be sure you’re prepared for your trip. Double-check your packing list, and if you’re bringing devices like a phone or tablet, don’t forget a US to Indonesia power adapter as well.
If you can, plan to visit Indonesia during the drier months. Rainy season puts a damper on the outdoor activities the country is known for, including scuba diving, surfing, and trekking. Some trekking routes close entirely during the rainy season due to mudslides, and ferries often get canceled as well. Visit between April and October, and you’ll be able to experience more (with less hassle). Peak tourist season in most of the country runs from June to September when the more popular areas get busy. Be sure to check current Indonesia travel advisories before you go.
Outside of Bali and a few other tourist hotspots, however, much of Indonesia remains off the beaten path and won’t be terribly crowded even in high season.
