Carbon River

The Carbon River area of the park offers a lush, rainforest environment with towering moss-covered trees, fern-lined paths, and the soothing sounds of rushing water. Accessible by gentle trails, this quiet corner of the park invites visitors to experience forests, taken in the river views, and a enjoy a peaceful escape from crowds.

The Carbon River area sits on the northwest corner of Mount Rainier National Park and feels wild, remote, and rainforest-like, with mossy old-growth forests and a braided glacial river. It’s a gateway to quieter hikes like Carbon Glacier and the Ipsut Creek area, offering a rugged, less-visited side of the park.
