  • Strenuous
  • Challenging
  • Mileage: 16.5 mi
  • Elevation Gain: 2,810 ft

Meet on Saturday, 9/28/19, at the passenger drop-off area for the Trailhead Direct bus that goes to Mailbox Peak.  (This is on the road just below the main parking area for Mailbox Peak where there is an outhouse.)
Time TBD - we will coordinate as a group.

Note: the Issaquah Transit Center only allows 24 hours of parking and the nearby Tibbetts Valley park & ride does not permit overnight parking (it officially closes at 7pm.) Probably we will take more than 24 hours so I wouldn't suggest parking at either location.

We will hike .2 miles along the road from where the Trailhead Direct bus drops off passengers for Mailbox Peak, then take the Granite Creek Connector Trail to the Granite Creek Trail to Thompson Lake. The trail is rather brushy in spots so I would recommend long-sleeved shirts and trousers. Trail surface can be stony so more supportive or cushioned shoes are probably a wise choice. On Sunday we will retrace our steps back to catch the bus.

If you are NOT planning on using public transit you will need a Discover Pass to park at the Granite Creek Connector trail pull-out or in the Mailbox Peak area parking.
