This quest can be tricky as you'll need to visit all three locations not just one or two, and they're quite spread out. Feel free to take multiple games to complete this quest if necessary.

None of the locations are named, instead they are just generic POI.
The three locations are very spread out, so it will be difficult to achieve this quest in one match without a vehicle.
The good thing about this mission is what once you arrive at the location, it's job done! No need to interact with any items or NPCs. Once you arrive at the location, the quest should update to show you have visited.
If you do choose to drive a vehicle to complete this quest, you do not have to exit the vehicle for it to register. Just try not to drive a car into the lake!
