BART will provide extended service on Halloween weekend to accommodate what will probably be the most busy weekend for Bart riders since the Pandemic started. People will be getting out to enjoy the Halloween festivities as well as hitting up the final day of Outside Lands. The current service schedule has BART closing at 9pm on Sundays, but they are planning to provide hourly late night service on all lines- with no stops at SFO or OAK airport stations. Make sure to check the schedule before you head out and if you don't already have one, get a Clipper Card to get in and out faster.
Plans to bring back late night service as a part of their regular schedule are scheduled for Feb. 2022.
