RV Guide


Located in southeastern Washington, Lewis and Clark Trail State Park is a riverside retreat with excellent fishing and boating. The 36 acres of alder, ponderosa pine, and maple trees give you plenty of shade as you relax along the cool waters of the Trouchet River.

The park, although small, has a well-maintained mile-long trail that takes you through the old growth forest. You’ll be able to spot bird species such as red-tailed hawk and orange-crowned warbler, as well as deer, coyotes, and foxes. There are a number of picnic tables along the water where you can relax and enjoy the shade, as well as a kitchen shelter that can be reserved in advance.

The park’s 24 RV campsites can be reserved in advance online, and offer shaded, secluded camping along the river. You’ll be near the park office, and have views of the water from your campervan.
