Most of the country is forested and rough; lightly in the south with large agricultural settlements, more thickly wooded and mountainous to the north.

A continuous line of mountains forms the region’s entire northern border, acting as both a barrier to forces beyond and as a home for numerous wild peoples, beasts, and monsters. This spine of mountains, running the length of this northern border, is made up of several seperate ranges linked together. In the west, they are called the Cruth Mountains, and are notable for their soft, greenish-tinged hornblende and the frequency of their landslides. In central Traladara, basalt is more common, and the mountains here are called the Black Peaks, so named for their ebony promontories. In the east, the range joins the much larger Altan Tepes Mountains and has the tallest peaks in the region. Here, the mountain range broadens, continuing north toward dwarven Rockhome in one direction and turning sharply southeast into the imperial lands of Thyatis in the other. The highest peak of the range, Mt. Tarsus (alt. 11,380 feet) stands to the east somewhat beyond the borders usually ascribed to the region. Forest vegetation thickly covers these mountains, gradually thinning to bare rock toward the peaks. The average height of mountains in the Black Peak and Cruth ranges is 4,000-4,500 feet. The Altan Tepes rise from an average of around 4,000 feet in the west to 9,000 in the east; a number of peaks jut above the timberline. South of this huge range are miles and miles of foothills thickly covered with forest. In the western reaches of Karameikian territory, hilly country extends to the shores of the Gulf of Halag, divided by several small river valleys; in eastern Karameikos, the most southerly foothills lie within 20 miles of the coastline. Most of the rest of the region, including all of the larger population centers, is cradled in the crescent formed by these hills, wedged between them and the Sea of Dread to the south. It is flat, pleasant land, sometimes with gently rolling hills, covered with woods and heavy forest. The land slopes very gently from the northern mountains to the southern coast. The northernmost flatlands (the Cruth lowlands in the west) are about 1,500 feet above sea level; the flatlands south of the Black Peak Mountains rise to about 1,000 feet above sea level.
Traladara is a thickly wooded region. In the north, pine forests cover the mountain slopes and the hillsides. As travelers move farther south, they encounter more hardwoods – especially oak. In the southernmost parts of the Dymrak Forest in the east, ancient oaks tower into the sky as far as the eye can see. There are three great tracts of dense forest in the region. The Achelos Woods sprawl in the far west, near the border with the nation of Halflings (known to themselves as the hin) called the Five Shires. It remains largely unexplored, uninhabited by humans (except for the soldiers garrisoned at Riverfork Keep), and somewhat dark-hearted. The woods are commonly blanketed in thick fog that drifts in from the Blight Swamp to the south. The Radlebb Woods sit in central Traladra. The forest is inhabited by the majority of the Callarii Elves. Less dark and ominous than the western tract, it still has its dangerous wild animals, rogue monsters, and the Callarii. In the southeast lies the Dymrak Forest, the most densely wooded area in the region. It stretches from the borders of the Barony of Kelvin to the border of Thyatis. A mighty hardwood forest, its floor never sees the full light of day. A number of nonhuman tribes call the Dymrak home, including several tribal bands of humanoids, as well as the Vyalia Elves in the east and a few settlements of Callarii elves in the west. Most of the remaining area of Traladara is lightly wooded – scattered small forests with patches of clear terrain suitable for pasturage and tillage. Humans settle in these areas most comfortably. The Blight Swamp, near the western border shared with the Five Shires. Mangrove forests are the dominant feature here. One large area of moors occupies the land northeast of the Barony of Kelvin. These moors are made up of flatlands and rolling hills with small rivers and streams trickle through, with vegetation predominantly sparse and scrubby underbrush.
The Traladaran people are a diverse population; there are a number of different ethnic groups living near to and, quite often, amongst each other.
