Administration of the park, which includes both federal and state lands, is a cooperative effort of the National Park Service and the states of Oregon and Washington. The National Historical Park was dedicated on November 12, 2004. After reaching the Pacific Ocean, the Corps of Discovery camped at Fort Clatsop in the winter of 1805–1806. The park features a replica of the fort and a nearby visitor center. Also included in the park are several sites on the north bank of the river in Washington and other sites in Oregon.

Astoria Regional Airport (IATA: AST, ICAO: KAST, FAA LID: AST) is a joint civil-military public airport in Warrenton, three miles southwest of Astoria, in Clatsop County, Oregon. The airport is owned by the Port of Astoria and is the home of Coast Guard Air Station Astoria. The airport has no airline flights. Flights to Portland International Airport were most recently provided by SeaPort Airlines from March 2008 until Spring of 2010. Until 1974-75 Astoria had flights on West Coast Airlines and its successors. Federal Aviation Administration records say the airport had 1,851 passenger boardings (enplanements) in calendar year 2008, 1,531 in 2009 and 3,482 in 2010. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation facility based on enplanements in 2008 (the commercial service category requires 2,500 per year) but it would be categorized as commercial service - non-primary based in enplanements in 2010.

Fort Clatsop was the encampment of the Lewis and Clark Expedition in the Oregon Country near the mouth of the Columbia River during the winter of 1805–1806. Located along the Lewis and Clark River at the north end of the Clatsop Plains approximately 5 miles (8.0 km) southwest of Astoria, the fort was the last encampment of the Corps of Discovery, before embarking on their return trip east to St. Louis. The Lewis and Clark Expedition wintered at Fort Clatsop before returning east to St. Louis in the spring of 1806. It took just over three weeks for the Expedition to build the fort, and it served as their camp from December 8, 1805 until their departure on March 23, 1806.The site is now protected as part of the Lewis and Clark National Historical Park, part of which was formerly known as Fort Clatsop National Memorial until 2004. The original Fort Clatsop decayed in the wet climate of the region but was reconstructed for the sesquicentennial in 1955 from sketches in the journals of William Clark. The replica lasted for fifty years, but was severely damaged by fire in early October 2005, weeks before Fort Clatsop's bicentennial. A new replica, more rustic and rough-hewn, was built by about 700 volunteers in 2006; it opened with a dedication ceremony that took place on December 9. The site is currently operated by the National Park Service.

Youngs Bay, or Youngs River Bay, is located in the northwestern corner of the U.S. state of Oregon. The Youngs River meets the Columbia River at this point, which is situated between Astoria and Warrenton. The bay is named for the Youngs River, which was discovered in 1792 by William Robert Broughton of the Vancouver Expedition. The river was named for Admiral Sir George Young of the Royal Navy. There are two road bridges that cross the bay, with the busiest being the new Youngs Bay Bridge, a vertical-lift bridge completed in 1964, that spans approximately 1.75 miles (2.82 km) and is a two-lane part of U.S. Route 101 running north to south. There is also the Old Youngs Bay Bridge about two miles to the east, completed in 1921. From 1895 to 1986, a 1.6-mile (2.6 km) railroad trestle also crossed the bay. Built in 1896 for the Astoria and Columbia River Railway Company, it was later transferred to the Spokane, Portland and Seattle Railway, and finally to Burlington Northern Railroad. It included a swing-type draw span. The New Youngs Bay Bridge passed over the top of the SP&S bridge near the north river bank. The railroad bridge was used for the last time in 1982 and was dismantled in 1986.The bay is fished extensively for sturgeon and salmon when in season. Most of the gillnetting community moors and fishes in Youngs Bay. The bay can be seen rising and falling significantly with the tides created where the bay meets the Columbia River, which meets the Pacific Ocean approximately 10 miles (16 km) to the west.

The New Youngs Bay Bridge is a vertical-lift bridge over Youngs Bay on U.S. Route 101 (US 101) between Astoria and Warrenton. Including the approaches, it is 4,200 feet (1,300 m) long and was completed in 1964. The road bridge had been proposed since 1948 and was approved by the state government in the late 1950s. The routing across Youngs Bay for US 101 was chosen in 1955 over a more inland alignment that would have avoided the bay entirely. Construction began in March 1963 and was dedicated on August 29, 1964.The bridge was built to the west of, closely in parallel to, a 1.6-mile (2.6 km) railroad trestle which also crossed the bay. It was built in 1896 for the Astoria and Columbia River Railway Company. The New Youngs Bay Bridge passed over the top of the railway bridge near the north river bank. The railroad bridge was used for the last time in 1982 and was dismantled in 1986.
