New Trailhead Direct Routes and Stops

Trailhead Direct is back, now with new route options that better connect you to popular hikes in the Greenway!

This transit-to-trails shuttle service makes it easy to catch a King County Metro bus to numerous recreation destinations, including the Issaquah Alps, Mailbox Peak, Mount Si, and new stops at Little Si and Cougar Mountain’s Sky Country Trailhead.

Starting April 20, Trailhead Direct will provide weekend and holiday service every 30 minutes from Seattle’s Capitol Hill Station, University Street, Mount Baker Station, and now the Tukwila International Boulevard Station, with additional stops at Eastgate, Issaquah Transit Center, and North Bend Park-and-Ride.

Trailhead Direct was first launched in August 2017 as a pilot project sponsored by King County Metro and King County Parks with the mission to connect more people to the regions great outdoors while additionally reducing dangerous vehicle congestion at trailheads. Trailhead Direct brings to life the longtime Greenway dream of accessing wilderness on the Metro. Transportation options like Trailhead Direct are more important than ever to sustainably connect our growing urban population to our beloved outdoors, and to make access to public lands more equitable. In 2018, Trailhead Direct provided more than 10,000 rounds trips. Thanks to additional funding from the City of Seattle, King County was able to expand and modified this service based on customer feedback from last season.

New routes and stops create a better-connected transportation system that offers hikers opportunities to hike from one Trailhead Direct drop-off location to a different pick-up location. All routes now connect at the Issaquah Transit Center where people can more easily transfer to Trailhead Direct routes. Please see below the changes and additions that were made.
