Tickets to visit Mount Vernon with kids are available for purchase online at a discount, as are the Potomac River boat cruise tickets. Special tours can also be booked in advance online. You may not bring in outside food or drinks (other than bottled water).
Summer months at Mount Vernon are hot, humid, and very busy. Spring months are full of school groups. Fall is a beautiful time to visit. The grounds are extensive, so wear walking shoes and comfortable clothes. Most of the area is stroller-friendly, albeit hilly, but you must park the stroller outside before visiting the mansion.
Mount Vernon is open 365 days a year. I would recommend touring the mansion and grounds in the morning, cruising mid-day, and visiting the museum in the afternoon. Daily schedules are available at the ticket window for planning out your day.
Potomac River cruises are only available mid-March - Fall. Summer is very hot, humid and busy. Spring is full of school groups. Fall is a beautiful time to visit!
Purchase tickets in advance online for a discount. If you live in the area or plan to return, a Family membership might be worth it. You can visit for free for a full year. Members also get discounts on food, shopping and exclusive invites to events.
