2026 Trailhead Direct Season Maintains Two Weekend Routes to Hiking Destinations

King County’s Trailhead Direct shuttle service launches its 2026 season this Saturday, offering weekend service to Mount Si and Issaquah Alps trailheads through August 30. Shuttles run every 30 minutes from Sound Transit light rail stations, with fares mirroring regular Metro bus rates ($3 adults, $1 reduced fare, free for youth under 18). The service drew 12,263 riders last year and features wheelchair-accessible vehicles with bike racks, though some popular Issaquah Alps trailheads won’t be served this season.
