To get to these secret falls, you must first figure out where Sumba Island is. (It’s in Indonesia.) Then you have to book into Nihiwatu, one of the world’s most raved-about resorts. (Really, it’s won nearly every accolade possible.) From there, it’s a 45-minute drive through the Wanukaka Valley, on Sumba’s south shore, and then a 90-minute hike to the main event: a cascade, framed by 300-meter cliffs, whose water crashes into a swimmable blue lagoon.
