Head north from SE Maple Valley Rd onto Coal Creek Parkway. Turn off Coal Creek Parkway on to 133/NewCastle Golf Course Rd. 133rd turns into SE 66 the SE 68th. When 68th makes a 180 degree turn and becomes Lakemont Blvd follow Lakemont north. When you cross Cougar Mtn Way at SE 63rd make a right and continue up hill. You'll hit 184th, then 168th, 169th and finally 170th. Sounds confusing but if in doubt just keep heading uphill. Continue on till you can easily turn around on 65th almost exactly 100 vert ft. from the top of Cougar Mtn. This is the flip side of the Zoo climb and better yet much of it has a nice wide bike lane.
