Coronado State Monument where Francisco Vásquez de Coronado—with 300 soldiers and 800 Indian allies from New Spain—entered the valley while looking for the fabled Seven Cities of Gold. Instead he found villages inhabited by prosperous native people. Coronado's party camped near the Tiwa pueblo of Kuaua, one of the many villages encountered by the explorers. Kuaua, a Tiwa word for "evergreen," was first settled around AD 1300 by American Indians who had long known about the fertile land near the Rio Grand. Kuaua is an earthen pueblo excavated in the 1930s by WPA workers, who also reconstructed new ruin walls over the reburied original ruins. A square kiva, excavated in the south plaza of the community, contained many layers of mural paintings. These murals represent some of the finest examples of Pre-Columbian mural art in the United States. Both the kiva and one of the mural layers are reconstructed and open to visitors, while several of the preserved mural segments are open to viewing in the mural room of the visitor center. The visitor center, designed by noted architect John Gaw Meem, also contains prehistoric and historic Indian and Spanish colonial artifacts on exhibit with several hands-on components.

A second website, maintained by the Friends of Coronado, can be found here.

The site offers a short film, exhibits, lectures, workshops, and occasional recreational and educational events.

The Garibaldi Museum presents information concerning Captain Robert Gray; his historical vessels, the Lady Washington and the Columbia Rediviva; trade with the Native Americans of the Pacific Northwest; and the maritime world of the 1700's. Gray discovered the Columbia River on May 11, 1792. During James Madison's second term as President (1813–1817), the U.S. used this discovery to lay claim to the Oregon Country. Among the museum displays are models of the Columbia Rediviva and Lady Washington; an 8–foot–tall reproduction of the Columbia Rediviva's figurehead; a half model of the same vessel, showing how the ship was provisioned for the long voyage; reproduction seafarers' garb; and musical instruments. One wing of the museum is devoted to the history of the City of Garibaldi, displaying pictures and artifacts from the turn of the century.

The museum offers exhibits, several of which are interactive; scholarships for local high school seniors and Tillamook Bay Community College students; and a 4th grade education program.

Fort Buford State Historic Site preserves remnants of a vital frontier plains military post. Fort Buford was built in 1866 near the confluence of the Missouri and Yellowstone Rivers, and became a major supply depot for military field operations. Original features still existing on the site include a stone powder magazine, the post cemetery site, and a large officers' quarters building which now houses a museum. Fort Buford, located near present-day Williston, was one of a number of military posts established to protect overland and river routes used by immigrants settling the West. While it served an essential role as the sentinel on the northern plains for 19 years, it is probably best remembered as the place where the famous Hunkpapa Sioux leader, Sitting Bull, surrendered in 1881.
