On this hike we'll be taking the TMT to the K-3 trail up to TM2 taking the connector over to the TM3 summit and coming down the TM3 trail. This is a fun alternative to up and down the TM3. The TMT/K3 is longer trip with a bit more elevation gain and more strenuous providing a good conditioning workout.

We will be may coming down in the dark, be sure to bring a working headlamp.

Please call if you are running late, I'll only wait around a few minutes for no shows, so if your like 10 minutes late you might miss the hike.

This is an early season conditioning hike to start getting in shape for the upcoming season, don't pack too much weight for the first few hikes. Do bring your 10 essentials, some water and maybe a snack for the summit.


This trip is one of a series of optional hikes for scramble course students to work on their conditioning, explore the foothills peaks and become better acquainted with the other students and scramble community members. These conditioners are also a great way to test out your gear in the field.

This trip is not a scramble, does not count toward graduation and is optional, however we strongly suggest that you participate in as many of these conditioning hikes as possible.

The leader(s) are scramble course graduates and instructors, but not necessarily official scramble leaders.  Sign-up is limited to students from the current year's scramble course. 

Depending on our ability to recruit leaders for these hikes, there might be more than one hike listed per day OR the group might be split into two separate parties, one faster and one slower.

Destinations might be one of these locations:

  • Mt Si - via the standard trail.
  • Mt Si - via the "old" trail that starts at the Little Si trailhead
  • Mt Tenerife
  • Mailbox Peak
  • Mt Washington
  • Rattlesnake Mountain
  • Tiger Mountain 1 from Issaquah High School (3000' gain/5 hours)
  • Others?
