Purple Knob loop, just South of Hero’s knob tends to be less frequented, possibly because it’s not as wide, or long, as Sweet 16.
It still however makes for an excellent run and can be combined with Hero’s knob to make a full day.
Purple Knob is usually approached from the south side, however this is a solar aspect and often has large cornices at the top.
An early start is recommended if solar heating is a concern.
