Just past the cutoff to Thorton Lakes, the fun begins on the way to Trappers Peak.
This is the only "climbing" that you'll get on Trappers as there is pretty much a boot path all the way to the summit (other than a short section across an exposed ridge). Trappers is rated as Class 3 and maybe this section is why. This section is short and is just a fun scramble.
