Step into the Fort Clatsop replica at Lewis and Clark National Historical Park, and you'll get a real sense of what the Corps of Discovery experienced more than 200 years ago. During peak visitor season rangers in buckskins offer demonstrations such as flintlock gun shooting, hide tanning, and candle making.
Check out the historic canoe landing and consider doing a hike on one of the nearby trails. If it starts to rain, take a break inside the Visitor Center. Inside you'll find informative films, displays, and a bookstore with Lewis and Clark related books, media and other high quality merchandise.
Don't forget to ask to become a Junior Ranger! The activity book is free and loads of fun. Lewis and Clark National Historical Park also hosts a number of free lectures and other special events throughout the year.
