Climb thru dense forest on ST paralleling creek. Cross fire road and continue up thru clear cut section and then on into more forested area. After hike-a-bike across scree field, find ST on right and continue to climb. Near the top, you'll roll thru grassy meadow and climb just a bit more until you summit Larch Mountain where a set of radio towers sit. Enjoy the view!
From there you have a few options: descend the way you came, follow loose gravel road south of radio towers to Thrillium TH, a steep, fast DH course that ends at your vehicle; or take the doubletrack to east of towers that joins the continuation of the greater Tarbell loop, an epic 20 miler.
NOTE: the gate near the top of Thrillium is open and a new parking lot has been installed including restrooms. You can park at top of Thrillium and ride up 1.5-2 miles to radio towers as a shuttle option to Cold Creek
