The most reliable and efficient way to get from Washington, DC to Rehoboth Beach without a car in 2026 is by taking the BestBus "Beach Bus" service. This specialized shuttle operates daily during the summer season and on weekends during the "shoulder" months, departing from major hubs like Union Station or Dupont Circle. The journey typically takes between 2.5 and 3 hours, depending on the notoriously heavy Bay Bridge traffic. The bus drops passengers off directly in the heart of Rehoboth Beach at the 219 Rehoboth Avenue station, which is just a short walk from the boardwalk and most major hotels. Another option is taking the Amtrak to Wilmington, Delaware, and then transferring to the DART First State (Route 305) bus, though this "Beach Connection" is primarily a weekend-only service and involves a longer total travel time. For those seeking maximum comfort, the BestBus offers free Wi-Fi and water, making it the preferred "hassle-free" choice for DC residents looking to escape to the Delaware coast for a weekend getaway.
