While Bali has long enjoyed a top spot on many travel bucket lists, this Southeast Asian stunner is brimming with hidden gems (and giant sea turtles) across every inch of its scattered landmass. Made up of more than 17,000 islands (yes, you read that right), Indonesia can offer a meditative and restorative escape, an adrenaline-inducing adventure, a laid-back retreat, or a party you'll never forget.
