Paying for Parking

You can pay at the automated pay station across from the kiosk (cash with no change given, or card), at the cash box at the Goodspeed trailhead, at the staffed kiosk on weekends and most holidays, at the Visitor Center, or online ahead of time. A California State Parks annual pass or the $59 Sugarloaf annual pass also works (hours and fees).

No Free Parking on Adobe Canyon Road

The operator's waterfall handout is blunt about this: there is no free parking along Adobe Canyon Road, even outside the park. If you only want the short walk to the falls, you still need a day-use pass for the pullouts (waterfall).

Accessible Parking

Van-accessible spaces are at the Visitor Center, the main day-use lot and the White Barn lot, with accessible parking at both ends of the Creekside Nature Trail. An accessible space is also next to the Robert Ferguson Observatory.
