All the Chief hikers and pad people walk on the road. There should be a path on the cliff side of the road from the highway to the Chief trailhead.
Between the Apron and the Chief there is a new trail
if you mean from the first parking lot to Chief trail head then you should park at one of the new upper three lots.
there are 4 or more now...and I saw a new site on the Apron Chief trail
It is getting too crowded up there on the weekends.
I saw one BC plate last weekend...and lots of taped up hands climbing on the apron.
