National Forest is the main setting for "Camping Can Be Cool". Similarly to the simply named City, National Forest is simply a national park. Mordecai and Rigby regularly plan trips to this place, every time using a secret camping spot in a restricted area. The secret camping area used by Mordecai and Rigby has a great view of a lake and or river with a water fall flowing into it. This area may be closed due to the fact that the Stag-man lives around this area of the forest.
- National Forest strongly resembles Yosemite National Park, USA.
- It is ruled by Stag-Man.
- This is the second Park seen in Regular Show, the first is The Park.
- There is only one known worker in the National Forest is the Park Ranger.
