The river was originally named the 'Upthascap River' by Charles Wilkes in 1841. However, it was renamed 'Carbon' in 1876 after the significant discovery of coal deposits along its banks. The area has a rich history of coal mining, which played a role in fueling transcontinental railroads.
The Carbon River area is located in a remote part of Mount Rainier National Park. There are no cafes, restaurants, or commercial lodging facilities directly at or immediately near the entrance. Visitors should plan to bring their own food and drinks. For accommodation, options would be found in nearby towns outside the park, such as Wilkeson or Enumclaw, or through backcountry camping with a permit.
The Carbon River Trail is unique because it was formerly a paved road, which was converted into a gravel trail after flood damage. This makes it relatively flat and wide, ideal for easy hiking and biking, and less strenuous than many other mountain trails in the park. It offers a distinct experience of an inland temperate rainforest at a lower elevation.
Yes, the Carbon River area is often accessible year-round due to its relatively low elevation (around 1,900 feet), even when other parts of Mount Rainier National Park are snow-covered.
