FREE Parking, gravel lot
DO NOT park in the main Arboretum Visitor Center lots. The Dahlia / Chinese Garden Parking Lot is 1.5 miles away from the main lots.
Due to the location of this lot at the far end of Three-Mile Drive, you will want to allow an extra 15-20 minutes to circumnavigate Three-Mile Drive 10mph traffic conditions.
