Cottonwood Beach

Cottonwood Beach is a sand beach along the Columbia River with a natural shoreline that stretches across a good length of the area. The site features two reservable picnic shelters equipped with tables, grills, running water, and electrical outlets for visitors and groups.

The beach became historically important when the Lewis and Clark expedition camped here for six days in March 1806 while returning from the Pacific. This location was the longest continuous camp they established in Clark County during their entire journey.

The site displays replicas of Chinook canoes and interpretive signs that reflect Native American life and early river exploration in this region. These elements show visitors how important this place was to the communities who lived and traveled here.

The beach is easy to access and has plenty of room for different activities, though weekends can be busier. It is better to visit on quieter weekdays if you prefer a more relaxed experience.

This location was the longest single campsite used by the Corps of Discovery in Clark County throughout their entire expedition, making it stand out among many other places they visited. This distinction shows how important this section of the river was to the explorers.
