Hidden Valley Nature Trail is a 1 mile
loop through a natural enclosure formed by rock formations.
Cattle rustlers are believe to have used this area in the 1880s
for hiding stolen cattle. There are thousands of gigantic
boulders and this places attracts a lot of climbers. In fact
this place seemed to be the climbing hub of the park as we saw
much more people climbing here than in other areas. The trail
winds between the massive boulders. Nice views, I took about
50 pictures of this place (ignoring Cris's protests) all of
them showing weird shaped boulders :)
