Olympia to Hoquiam
- Distance: 52 miles
- Routes: SR 8, SR 12
- Estimated Driving time: 1.5 hours
The tour traverses the coastal range passing from the inland salt water shores of the Puget Sound to the deep water Grays Harbor, opening out to the Pacific Ocean. West of Olympia the tour skirts the south shores of Eld and Budd inlets, the southernmost fingers of the Puget Sound, before climbing briefly through the Black Hills. Coming out of the hills the tour follows the winding course of the Chehalis River valley, passing through small lumber and agriculture based towns that extracted resources from the surrounding lands. The tour crosses multiple river drainages moving run off from the temperate rain forest mantle around the Olympic Mountains to the north. These include the Satsop, Wynoochee, and Wishkah rivers, as well as the East and West forks of the Hoquiam River all feeding into the Chehalis River. A central deep water channel carved by the river and subsequent dredging extends through Grays Harbor from the Pacific Ocean in to Hoquiam and Aberdeen and up river to Cosmopolis providing a key shipping lane.
