The small parking lot is usually full and Reed College is not allowing parking currently. Next best is usually neighborhood streets to the south. Another option is going north, but then you have to walk a fair distance uphill to get back to the entrance.
They have a small parking lot on site. Also, the college across the street offers parking options.
I parked across the street in the Reed College West Parking lot. From their website, on 6/6/2022: "Parking at Reed College is free and no permit is required."
Park in the neighborhood to the south east of the garden. It's a small hike, so make sure to drop off anyone at the entrance with low spoons.
We just parked on the street as we were there on vacation
If the parking lot is full as it usually is. Park down the street somewhere.
