Open every day except for very weird weather days like high winds. Check Lake Champlain Transit website at Ferries.com for hours. On rare occasion they might be closed site will tell you. I commute weekly from NY to home in VT using Ferry. Excellent inexpensive way to travel across lake. About half hour driving break with an available rest room stop. Check website.
They are open every day this time of year. I believe the first run is 6:30 AM.
