This challenge is part of the Midas Mission Challenges, the ultimate agent Fortnite Chapter 2 Season 2 focuses on. You'll have to travel to three different locations — The Agency, Hayman, and Greasy Graves — in one single game. There is no compulsory order in the visit of these places, but it's obviously recommended to visit them from East to West (or vice versa).
Map
Hayman
Your journey can begin by landing on Hayman — a sort of giant statue located southwest of Frenzy Farm. Once you have visited this notable place, don't waste time and head for the Agency. In order to continue your crossing more quickly, the best way is to take the motorized canoe docked near the small cabin on the lake.
The Agency
A place mentioned on your map, the Agency shouldn't be too difficult to find. You'll just have to pass right by the central island and this portion of the challenge will then be completed. Keep an eye out when you pass by Midas' lair, as players often land there!
Greasy Graves
Continue your journey to Greasy Graves, the landmark site that embodies the rubble of Greasy Grove's Durr Burger restaurant! You'll find it on the north-western edge of Weeping Woods. The easiest way to get there is to take a boat upriver from the Agency. You'll spot the place easily by spotting the moss covered hamburger.
