You can always read the five Steve Perry Conan novels. I think they're horrid, but that's because Perry is trying to make Conan's world look like a D&D world with a lot of different races in his books.
You might get inspiration there. Perry wrote five Conan novels. They all document, one after the other, Conan's first journey south, into the Hyborian lands.
The first one starts with Conan leaving Cimmeria, and the last one ends with Conan reaching Zamora. Conan is about 16-17 years old during these tales.
Besides adding a lot of demi-human type races to Conan's world (which I detest), it never made sense to me why Perry had Conan spend much of his traveling in the rugged mountains. In each book, Conan is in some mountain range, heading for Zamora.
I know there's a lot of mountains between Cimmeria and Zamora, and I know Conan is comfortable in the mountains because of his homeland.
But, can he make better time traveling through the mountains?
Conan's not dumb. Wouldn't he find the route that cost him the least amount of time, spending much time on the roads and flatlands rather than the rugged mountians where terrain does a number on your rate of speed.
The five Steve Perry Conan novels are, in chronological order:
#P1 Conan The Defiant - telling the story of Conan heading south from Cimmeria, standing at the mountainous juncture of Brythunia, Corinthia, and Zamora.
#P2 Conan The Indomitable - This one is full of D&D-ish "stuff". Just about the entire novel takes place underground as Conan finds his way through a long cave complex...in the mountains.
#P3 Conan The Free Lance - This adventure takes place...you guessed it..in the mountains. The Kezankians.
#P4 Conan The Formidable - And this adventure takes place...in a mountain valley! Between the Kenzankian and Karpash mountains. And, it's got half-giants! These aren't Ymirsh, either. They're honest-to-Bel-D&D-imagined-half giants! At the end, Conan finally sets foot on northern Zamora.
Those four books are Perry's Conan quartet, meant to be read back to back, although each contains an episodic adventure.
For Perry's fifth and last Conan book, he decided to set it a bit later in the timeline, as Conan leaves the hotbed of Zamora after becoming a master thief, heading west. Perry intended this tale to link Conan's early days in Zamora as a thief with the stories that happen in the west around that time, like Howard's The God In The Bowl.
#P5 Conan The Fearless - As Conan comes out of the Karpash Mountains (yep, you heard that right), he finds a nameless village in the mountain pass. I have no idea why Perry insists that all five of his stories take place in or near the mountains. This one starts off in a small Corinthian villiage that has grown up in the pass between Zamora and Corinthia.
In my opinion, The Fearless is Perry's best book (mediocre read). The original quartet, though, are just plain horrible. They're like reading not-so-good Forgotten Realms tales.
I'm sure my dislike of Perry's butchery of the Hyborian Age added to my disdain for the books.
Someone who's interested in a more D&D-ish Hyborian Age might very well like them...and get some good ideas from them.
