Weyerhaeuser

Located in Cosmopolis near the mouth of the Chehalis River, the Weyerhaeuser Boat Ramp provides convenient access to the lower Chehalis River and the Grays Harbor Navigation Channel. The launch features a concrete floating pier and covered fish shacks, making it a functional put-in for kayakers, canoeists, and motorboats. The site offers parking and is open year-round.

**Paddling Conditions:** The Chehalis River at this location is navigable by motorboats at mid-water levels, though low water conditions can expose large rocks near the launch area that pose a hazard to propellers. Paddlers should be aware of tidal influences and river conditions before launching. The area is suited for recreational paddling and fishing, with the river providing access to the lower estuary environment.

**Nearby Recreation:** The Grays Harbor National Wildlife Refuge is adjacent to this area, offering opportunities to observe coastal wildlife and wetland habitat. This location serves paddlers looking for lower river and estuarine paddling experiences in the Grays Harbor region.
