Exchamsiks River Provincial Park is in the Coast Mountains at the mouth of the Exchamsiks River on the north side of the Skeena River, about 42 miles (68 km) east of Prince Rupert and 31 miles (50 km) southwest of Terrace, British Columbia. The purpose of the park is to protect one of the last known unlogged old-growth maritime coastal Sitka spruce ecosystems.

The Skeena originates in northwestern British Columbia, forming a divide with the Klappan River, a tributary of the Stikine River. The Skeena flows for 350 miles (570 km) before it empties into Chatham Sound. The Skeena drains a watershed of 13,440,000 acres (5,438,975 ha). Major tributaries draining into the lower Skeena from the north are the Kasiks, Exchamsiks, and the Exstew Rivers, while the Gitnadoix River drains into the south bank. The Skeena River Ecological Reserve is at the mouth of the Eschamsiks and comprises three large and four small islands with the purpose of conserving unlogged floodplain islands for research on succession in black cottonwood communities.

Exchamsiks River Park covers 45 acres (18 ha), east of the Exchamsiks River at its confluence with the Skeena River. The park lies immediately to the north of the Yellowhead Highway. The lower Exchamsiks River contains many archaeological sites and is part of the asserted traditional territory of the Tsimshian people. Exchamsiks River Park was established in 1956 to protect one of the last known unlogged old-growth Sitka spruce-salmonberry communities along the highway corridor to the north of the Skeena River. Read more here and here.
