One if by land

The overland route is fraught with its own perils. The journey itself can be made in three days at full speed when the road is in good condition. Unfortunately, the road is seldom in pristine condition. The steep slopes and loose rock often cause blockage and erosion of the roadway, which can slow down travel time, not to mention weather conditions or ambush.
Generally, the added concerns only force a fourth day onto the trip, although extreme conditions can add more. The road up out of Chance is a slow and difficult climb, with many steep inclines. The positive part of this is that the town is built at the base of a particularly large peak, and the road makes a long, mostly straight climb around a spur of the mountain. After 12 miles, the road begins switching back and forth as it crosses steeper sections.
Eventually, the road drops down slightly into a high valley between this mountain and the next. There is a road running through this pass deeper into the mountains toward mines in the distance. The next ridge is much rougher and made of particularly loose gravel. The next third of the journey is arduous and slow, crossing high on the ridge, with a lot of loose, slide-prone rock above and below. This is a prime spot for ambushes due to its isolation and the vulnerability of exposure on the hillside. There are caves high along the slope where ettins like to dwell.
The last third of the journey features another road leading into the mountains east of this bowl to more mines. This road is fairly well traveled, since there are 2-3 large mines that send iron and silver down into the town of Aronsburg. The road is better kept, and quickly drops down into gentler slopes, where it runs through forested slopes and past the occasional farm. This also is prime country for banditry, with so many places to hide and disappear into the wilderness. It doesn't hurt that the road often sees well stocked wagons being carried up to the mines with food and other provisional supplies, or back with full coffers of ore straining the boards of the wagons holding it.
There are patrols that move through this area, nominally "protecting" travelers and tradesmen, although many of these tend to be mercenary, and barely less dangerous than outright bandits.
Shelter on the first and final third of the road is easy to find, although the protection it can provide tends to vary widely. The middle section is exposed, and not a good place to rest or find any shelter. Most travelers try to rest before and after crossing it, opting for long marches to try covering the distance in one day. This is countered by the condition of the road itself, and the malicious intent of the ettins above who look for such actions and intervene.
