THE END OF THE OREGON TRAIL INTERPRETIVE CENTER

The End of the Oregon Trail Interpretive Center offers the “Bound for Oregon” featured film, genealogy assistance for descendants of pioneers, and exciting and interactive exhibits that include period games and crafts like candle dipping and making a rag doll. Pack your wagon, dress like a pioneer, make butter and fill out a land claim, too! Outside the Interpretive Center, enjoy the heritage garden, a guided walk of our interpretive trail, and Abernethy Green with pioneer lawn games.
