*[[Burnt Ranch, California|Burnt Ranch]] is a small, rural community on Highway 299 in the Downriver area of the county. It lies above Burnt Ranch Gorge, a famed whitewater stretch of the Trinity River. The area around it is steep and forested, but there are many agricultural flats in the community proper. There is a volunteer fire department and an elementary school. The name comes from a settler's ranch that was burned by Native Americans.
*[[Coffee Creek, California|Coffee Creek]] is a small resort community on Highway 3 north of Trinity Lake. It sits where Coffee Creek meets the Trinity River. The community takes most of its economy from tourism, since it serves as the base camp for a popular trailhead into the Trinity Alps Wilderness. There are several guest ranches and resorts surrounding the community as well. It is home to a store, a pizza place, a campground and RV park, a church, and a fire department, as well as many guest accommodations in the surrounding area.

There are resorts and guest accommodations scattered along the river throughout the area. 
*[[Hayfork, California|Hayfork]] is the second largest community in the county. It lies in the Hayfork Valley, the largest agricultural region in the county, and derives a significant part of the economy from ranching. It used to be a mill town as well and a gold rush town until the closing of the Sierra Pacific mill and a slow decline in mining in the 1990s due to reduced timber stocks, consolidation, and environmental regulations. Businesses include an elementary and high school, fire department, multiple grocery stores and bars, as well as a gas station and tire shop.
*[[Hyampom, California|Hyampom]] is the only CDP along the South Fork Trinity River. It lies in the Hyampom Valley, one of the largest agricultural areas in the county, and one of the main economic drivers is vineyards. It sits at the foot of South Fork Mountain at the confluence of Hayfork Creek and the South Fork. The South Fork is one of the largest undammed watersheds in California, and provides critical habitat for salmon and steelhead, although the populations have suffered in recent years due to environmental issues.
*[[Junction City, California|Junction City]] is the most populous and uppermost community in the Downriver area. It is marked by a large flat along the Trinity River covered in gravel from gold mining in the 19th century.

The community's institutions consist of an elementary school, a store, a cafe, and a fire department. 
*Kettenpom California is a fairly large community located 10 miles southwest of Ruth. It is densely forested with some open terrain. 
*[[Lewiston, California|Lewiston]] is the third-largest community in the county.

*[[Mad River, California|Mad River]] is one of two larger communities in the county not in the Trinity River watershed, the other being Ruth. It lies along the Mad River where Highway 36 crosses it.

*[[Trinity Center, California|Trinity Center]] is the largest community on Trinity Lake, which brings in tourism and sustains the economy of the town.
