The terrain isn't showing in both the scene view and the game view, but when I build and run the game the terrain shows up. Thanks in advance for answering a complete newb (to unity) ^^
A little late but I'll write it for posterity, you may have unchecked the 'default' layer in the 'Layers' dropdown box.
For terrain not showing up in Scene View two things come to mind. The first, you may have accidentally unchecked your terrain in the Inspector window - it would be grayed out in the Hierarchy window if so. The second, you may have just moved the view far away from it. In the Hierarchy window click on your terrain, then mouse over to Scene window (without clicking) and hit the F key (also Edit-> Frame Selected) to focus on it.
For Game view, you must make sure you have a camera set up, that it is enabled (again, not unchecked in the Inspector) and looking at part of the terrain. Lastly with the camera selected, in the Inspector under the Camera component look at the Near and Far clip planes, by default they are 0.3 and 1000, respectively. You can right-click the line that says Camera and hit Reset to bring these back to default.
Hope this helps..
Jumping in with a note here: I had this same problem with the terrain not showing, only I had all the layers activated. After trying a lot of things I went to Window → Layouts → Revert to factory settings, and that did the trick! Now the terrain is showing as it should.

I accidentally had 2D set
I also had this problem and it was the camera clipping. If you have very large terrains you may have to put some ridiculously high number
