Cities: Skylines

Before we dive into this achievement, please check A Rabid Meerkcats guide on the "Coaster Tycoon" achievement, as well as Drachen77s guide for the "Z00" achievement, as they are in essence the exact same task, repackaged. They have already explained to process better than I can.

Please keep in mind that a shoreline is REQUIRED, as two of the buildings are on the water. You can easily extend the area of your park and paint a straight line to the desired area if you've already started. They don't need to be connected to water, have power a road connection.

The exact building requirements are:

-Nature Reserve Main Gate (Or small Nature Reserve Main Gate)
-Nature Reserve Side Gate
-Campfire Site #1
-Campfire Site#2
