Once a popular route for travellers seeking to cross the inhospitable Brazen Peaks from Osirion to Katapesh Serpent's Canyon is now considered too dangerous to make an effective trade route. As trade has declined and the gnoll presence increased Serpent's Canyon has stopped being used as a trade route, now only a few nomad travel the canyon and even they are swift and cautious when using this route. The canyon itself winds through the entire width of the Brazen Peaks from the deserts of Osirion to the Uwaga Highlands of Katapesh. The valley has steep, rocky sides and a sandy bottom, winds howl through the canyon all year round but are particularly bad in the spring and autumn. The canyon floor is cool for most of the day, the only time it gets hot is around midday when the sunlight can reach the canyon's floor.
