2025 Trailhead Direct Routes

King County Parks has announced that Trailhead Direct is returning in 2025 on weekends from May 24 to September 1. Additionally, the service will run on a few holidays, specifically: Memorial Day (Monday, May 26), Independence Day (Friday, July 4), and Labor Day (Monday, September 1).

Trailhead Direct consists of two routes, one from Capitol Hill station to Mount Si and one from Mount Baker station to the Issaquah Alps. These are the same routes as last year, with a few minor changes. Both routes will now stop at South Bellevue Station instead of Eastgate P&R. The Mount Si route also been slightly extended to start/end at E Denny Way & 16th Ave E in Capitol Hill. The Issaquah Alps route will now run every 30 minutes and will start running an hour later than it did last year.

The Mount Si route runs every 30 minutes and stops at the Mount Si, Mount Teneriffe, and Little Si trailheads. From Capitol Hill, the route travels downtown to stop on 4th Ave near Symphony station. On the way to the trailheads, the route stops at South Bellevue Station and North Bend P&R.

Issaquah Alps Route

The Issaquah Alps route runs every 30 minutes and stops at the Margaret's Way, Chirico Trail-Poo Poo Point, Squak Mountain, the High School Trail, and East Sunset Way trailheads. Starting at Mount Baker Transit Center, the route stops at South Bellevue Station and Issaquah Transit Center before stopping at each trailhead.

The High School Trail and East Sunset Way trailheads are less than a 20 minute walk from stops served by ST Route 554 and Metro Route 208.
