While indoor services at Lewis and Clark National Historic Trail's Omaha Visitor Center remain closed, visit our rangers at the Trail's outdoor visitor center! Located outside the building's north doors, the outdoor visitor center will be able to provide you with Lewis and Clark National Historic Trail information, as well as Omaha-area orientation. America the Beautiful, Senior, Access, Military and 4th Grade passes will all be available. We can only accept credit/debit cards for pass purchase. Outdoor visitor center operations will be canceled in the event of inclement weather and are subject to staffing levels.
