You park downtown cda, by the timberline adventures tour in cda mall. They provide transport bus to the zip line
We parked in the docks/Tubbs hill parking lot. We did the 7 line tour and I paid for 4 hours of parking. I believe we had about 20 minutes left when we returned. However we had a super small group, only 4 people. To be safe, I'd pay for 5 hours parking.
The best place to park is in the paid parking lot at MceEuen Park entrance in on the corner of front & 3rd street.
