Six Flags Fright Fest from Davis: what's actually on

Search for Fright Fest in Vallejo and you land on a Six Flags page that looks right. Check the year on it first.

On September 13, 2026, the events page for Six Flags Discovery Kingdom listed two autumn events: Tricks and Treats, "Saturdays & Sundays, September 19 - November 1, 2026", and Oktoberfest, "Saturdays & Sundays, Sept. 12 - Nov. 1, 2026". Fright Fest was not one of them. The park's Fright Fest page was live the same day and still read "Select Nights, September 20 - November 2, 2025".

So open the park's events page and its calendar for your own date before you plan anything else. Tricks and Treats is described as a daytime event, before dark. That is a different trip from the one most people are planning.

The closing time is the part that surprises people

The park is at 1001 Fairgrounds Dr, Vallejo (directions), and its calendar shows autumn operation on weekends only. We checked two October Saturdays on September 13, 2026: both October 3 and October 31 read 11:00 AM to 8:00 PM. Check your own date — the calendar is set per day.

Eight o'clock, not midnight. Do not plan around a late night that isn't happening. And from the park's code of conduct: "All guests are required to leave park property once park operating hours have ended for the day." Waiting it out in the lot is not a plan.

Two rules from that same page. Guests 15 or younger "must be accompanied by a chaperone who is at least 21 years old … after 4:00 p.m. local time to close" — relevant if a younger sibling is coming. And outside food and drink are not allowed in; there are lockers near Main Plaza.

Parking is paid, and that is the whole argument for one car

The park's parking page listed Daily General Parking at $39 and Daily Preferred Parking at $49 on September 13, 2026. Check it before you go.

It is one charge per car, not per person. A car with one person in it pays $39. A car with four people in it pays $39. Everything else here follows from that.

Transit, honestly

The train does the Davis end well. Capitol Corridor lists Davis (DAV) and Suisun-Fairfield (SUI) among "18 stations between San Jose and Placer County". There is no Vallejo station on that list, so the train alone never reaches the park.

The last mile exists too. SolTrans Route 1A is a loop out of Vallejo Transit Center that stops at Sage & Fairgrounds, by the park, and its timetable has a Saturday and Sunday column.

The piece in the middle is the problem, and it is a problem of hours, not of service.

1. The bus that links Vallejo with the Suisun-Fairfield Amtrak station is SolTrans Route 60. On Saturdays only some trips continue north of Vallejo to Fairfield and the train, and the last of those leaves Vallejo before the park's 8pm close.
2. On Sundays, every Route 60 trip runs between Vallejo and El Cerrito del Norte only. None goes north toward Fairfield at all.
3. The intercity bus on this corridor is now SolTrans Route 40, BART Concord to Dixon Park & Ride. Davis is not a stop on it, and it runs no Sunday service.
4. FAST local buses "operate Monday-Friday, 6 am – 8 pm, and on Saturday, 9 am – 5 pm."

Together: a daytime path down, with changes, and nothing that brings you back to Davis from Vallejo at the end of a weekend park day. Do not take our word for the times. Open each operator's timetable for your own date and write down the last departure. If it lands before the park closes, a car has to be in the plan.

Going with people who are already going

That is what TAGO is for: a carpool for students. You sign in with your .edu email, say where you are going, and see who else is going the same way. Nobody is dispatching anything; it is people with a car and people without one, sharing the cost of a trip that was happening anyway.

The way back is planned with the way out. For events and places, the return leg is part of the plan rather than a scramble in a parking lot you have just been asked to leave.

Your share is capped. What a rider contributes can never exceed the IRS standard business mileage rate for the day of the trip. That is a legal ceiling on cost-sharing, enforced in the code behind every trip, not a promise in an ad. Past the first eight miles the per-mile rate eases down, so the run down to Vallejo costs less per mile than a hop across town. More in how ride costs split.

If you are the one with the car: two in the car puts you in the carpool lane. Riders chip in for a drive you were making anyway, capped at that same rate. Nobody gets taken across town — a rider can be dropped at a transit stop already on your route, and you set the pickup point. Afterwards you rate your riders on how they treated your car and the ride, and they rate you back.

Nobody can promise a car will be there. It depends who is going, which is why you post this one early rather than the morning of. Six Flags Discovery Kingdom on TAGO shows how many people are going; routes and names stay private until you sign in with your .edu.

Before you commit

1. Open the park's events page and calendar for your date. Confirm what is running and what time it closes.
2. Check the parking charge for that day. It is per car.
3. Look up the last weekend departure from Vallejo back toward Davis. Write it down.
4. If it is earlier than the close, you need four people and one car, not four plans.
5. Sort the ride back the same hour you sort the ride down.
