Located in the southeast corner of the park, Ohanapecosh, named for a Taidnapam (Upper Cowlitz) Indian habitation site along the river, is thought to mean "standing at the edge." Situated among Douglas firs, western red cedars, and western hemlocks, visitors to Ohanapecosh can experience the beauty and complexity of an old-growth forest. The east side of the park is also somewhat drier and sunnier than the west side, making it a good destination when Paradise and Longmire are wet and foggy. Ohanapecosh is not accessible in winter.

Ohanapecosh is located 3 miles (4.8 km) north of the park boundary on highway 123 and 42 miles (68 km) east of the Nisqually Entrance. - NPS
