Maps are one of our favorite parts of fantasy literature.
They literally map out the world where some of our favorite characters live. They can illuminate the landscapes of our dreams or delve into the depths of our nightmares. We hope to have a collection of fantasy maps here, real soon now.
Of course, even though I've used Campaign Cartographer a lot in the past, there are a lot of ways to make maps.
There are numerous tutorials on the web, but one of the better tutorials that I've seen is How to draw nice maps, by Mark Rosenfelder. It's a good, and simple, method for drawing regional maps on the computer. Look around his site, the results speak for themselves.
Also, the cartographer who does a lot of the maps for Wizards of the Coast has a site.
You can check it out at Maldin's Greyhawk - A Guide to Mapmaking, by Denis Tetreault. His maps are, in my opinion, quite beautiful, so it's worth a look.
Lately, I've been looking into using my iPad Mini and my Apple Pencil to draw maps via Procreate.
A great resource for that is Map Effects. This site not only sells all kinds of Procreate brushes and tools specifically for mapping, including packages of tools geared toward everything from large area maps to city maps to dungeon and house maps, but also hosts a long list of easy-to-follow tutorials as well. I cannot say enough about Map Effects, actually. The resources are top notch and the proprietor is a good guy.
I hope to share more maps in this style soon!
Here is an example of what Campaign Cartographer can do.
This is a map of Ethshar, as originally designed by Lawrence Watt-Evans. I took his BMP, imported it into Campaign Cartographer and traced it out to this.

Here is an example of a map I made for my own pleasure. 
It's based on the idea of a world that was created by a god pushing his hand into the world. Where the ocean stuck to his hand, islands and continents formed. It struck me as an interesting creation myth, so I explored it a little with a map. I did this "freehand" in Campaign Cartographer, without using a scan of any kind.
