This is the easier of the two Lassen ascents – the grade is mild throughout, never exceeding 7.5%.  As can be seen from our Lassen North slideshow, we travel through heavily forested terrain for nearly all of the ascent.  The view opens towards the top of the climb and we have good views of the Cascade Mountains surrounding us, although the southern ascent offers the more epic views during the climb. The roadway is excellent on this side of the mountain, and traffic is mild and moves at a very safe speed – this is a safe climb.
