One option for spicing up (and speeding up) the access to Giant's Workshop is to ride a bike there on the carriage road, rather than hiking.
(the hike is not bad tho, and there are several ways you can get there, but each is probably 2-3 miles each way of "boring" hiking)
Park at the W. Trapps lot, ride Overcliff or Undercliff to Giant's Workshop, chain up yer bikes to a tree there, hike it, then ride back the opposite way you came (for variety's sake)
Just some additional food for thought... the Coxing Trailhead we'll see the blue trail and we just have to follow it to the yellow and then it's follow our noses right?
That's pretty much it. Blue trail departs from near the kiosk at the back of the lot.
Be prepared for some epic talus scrambling as you get closer. The M-dog had to resort to a few points of aid to get thru some of the dicier sections.
Oh, and I checked, the 'A Rock with A View' booklet is $7.95 - cheap at twice the price.
