Parking is the same rate as in downtown: $2 per hour. The arboretum currently (March, 2020) has a mix of free and paid parking. There are two paid lots directly adjacent to the Visitor Center, on either side of Fairview Blvd. There are also a number of free spaces along Fairview Blvd itself, as it passes in front of the Visitor Center. These spaces are often full, especially in nice weather, but turn over fairly frequently. Additionally, there are several pull-out spots within the park itself, along Fischer Lane, as well as near the Winter Garden, along SW Cascade Lane. These locations can be hard to find, however; especially the small Winter Garden parking area, which holds a maximum of 4 cars.
From Washington Park website: PAY TO PARK Payment is required for all numbered parking spaces in Washington Park, year round. If lots are full, overflow parking is available at Sunset Transit Center. 100% of all pay-to-park revenue stays in Washington Park.
