Need some help with custom map install?

Hey all I'm new here but been playing TF2 for many years. I just got back into the game and was looking into some custom maps, and I been looking for tutorials and guides on how to get all this set up but I just can't put 2 and 2 together.

I have thus far downloaded 3 maps and extracted them into the ..\Steam\steamapps\{your Steam username here\team fortress 2\tf\maps

I got that much of the procedure.

Now where I am stumped at is what do I do now to access those maps?

I have them installed into the correct directory but I do not understand how I have to go about opening up TF2 and actually locating and playing on the maps by myself for some training purposes.

Any help would be greatly appreciated, and I have used the search feature for the forum and couldn't find anything to help either.

Thanks!
