We have good news on the parking situation along the waterfront. The City of Wenatchee has added some additional public parking spaces on Worthen street — just south of the pedestrian foot bridge and across (west) from the Hilton Garden Inn. See photo. This gravel lot is open 24/7 and can handle some ~20 cars. It is only a short walk to Pybus Market and the Apple Capital Loop Trail.
The lot is open to the general public.
