We wanted to do Tarryall too but the weather was bad and we decided to cut it short. This was PLENTY because all off-trail.
Harder than the Easy B rating because of all the steep and continuous up and down. Waypoints re riverside snack spots and 360 degree meadow view spot. Lots of sun exposure also. S. Boulder Creek. Better in April or May? Up Hwy 72 Coal Creek Canyon, then R on Crescent Park Drive to R on Gross Dam Rd. No fee parking lot. 38 miles.
