King County Metro ORCA card
We recommend that hikers get an King County Metro ORCA Card, so you can use Metro services without bringing cash or exact change for the bus ride. The new myORCA mobile app and website makes paying for transit rides in the Puget Sound region even faster and easier. Of course, if you use public transportation daily, then you already know about it. But if you don’t, it’s a handy thing to know.
An ORCA card or myORCA mobile app can be filled with a small amount of cash and never expires. (I keep one on hand for trips to the airport, link Light Rail use, snow days, or any other public transportation need that might crop up. It has saved me more than once!)
About Trailhead Direct Program
The project was developed beginning in the summer of 2017, in response to growing vehicle congestion at several popular trailheads, where illegally parked vehicles along busy roads created significant traffic hazards and safety concerns. Trailhead Direct is a pilot project co-led by King County Metro and King County Parks.
Trailhead Direct provides an incredible opportunity for people to access and connect with their public lands. It reduces the number of cars on the roads and at our trailheads, while increasing the number of people who are able to experience some of the greatest trails in the country. Each person who steps off the bus and onto one of our trails has the opportunity to fall in love with the outdoors and become a champion of our public lands, helping ensure we preserve these lands for generations to come. — Hilary Franz, Commissioner of Public Lands
King County agencies had help from a number of partners in developing the pilot program, including Mountains to Sound Greenway, Washington Trails Association, The Mountaineers, Issaquah Alps Trails Club, Outdoors For All Foundation, TOTAGO (Turn Off The App – Go Outside!), REI, The Wilderness Society, Washington Department of Natural Resources, City of Issaquah, Si View Metropolitan Park District and the U.S. Forest Service.
Washington Trails Association is a proud partner of Trailhead Direct. Transit-to-trails services are key to making our region’s wonderful trails accessible to more people. It also helps trailheads meet the growing number of hikers, without adding more cars to already crowded parking lots. We’re excited Trailhead Direct is back for the 2019 hiking season and are working to ensure it’s an ongoing option for King County hikers. — Jill Simmons, Executive Director, WTA
