I'm trying to make a mod. I have a lot of coding experience, so I'm very comfortable looking at source code for examples/explanations. I just have no idea where the Forge/Minecraft sources are located.

For instance, if I want to make some kind of a multiblock structure, where could I look at the code for Nether portals?

Documentation is in the code as Javadoc comments.

Force src is here (including test mods):

You might find this tutorial project useful:

In order to find the code for Nether portals, you need to know a bit about the objects and datastructures used by Minecraft; that's where the various tutorials around the web can be a big help. The source code itself is generally poorly documented (very few comments in vanilla code, and somewhat patchy comments for the Forge code) and often the names of methods can be misleading or even wrong, because the code has been decompiled and then manually deobfuscated by crowdsourcing.

 

So for example for NetherPortals, the relevant code is in NetherPortalBlock and PortalSize, but it will be difficult to understand what's going on.  You might be better off with BedBlock or DoorBlock but even those are likely to be hard work until you have a number of the key concepts around blocks and blockstates under your belt.
