Climb Summary

WOW – and, we don’t write that very often! This is a scorcher, no doubt about it. Short, stout, brutal, murderous!! This is (along with Cougar Lane in Santa Rosa which is a private road) the steepest paved public road in Sonoma County that we have ever encountered. Pitches hit 27% according to our Garmin and it feels that way – we had to stand and really mash the ring to get up the 1/10 mile major pitch – with a 30t, by the way! If you want to test your Super-Steep-Kick-Butt-Pitch ability – take this, because it’s The One!

Note the MapMyRide elevation grid below and its 1/10th mile of 23-27% pitch; a very rare elevation profile.

Traffic/Roadway Surface: The roadway is very narrow (a true one-laner), but the "speed" limit is 5 mph, so we are safe on this monster - even the cars have a go of it getting up the thing.
