On Fort Sill there are multiple museums that are super cool to walk through! If you do not have a current Fort Sill Visitor Access Pass or DoD ID Card, you will need to register at the Visitor Control Center (VCC), building T6701. The Visitor Control Center is located on the southeast side of Bentley Gate on Sheridan Road and is open 0600-2100 hours, 7 days a week. The VCC phone number is 580-442-9604
