The majority of the hike is off limits to dogs, and much of it is shaded. There's also a good amount of people hiking on the trail (so you feel safer from mountain lions!). As for wildlife, we saw some medium sized paw tracks in the mud (not sure what animal made them), a hawk, and a couple of very adorable little bunnies munching on grass.
Now here's the biggest tip if you're hiking the canyon: Watch out for hidden cameras at the stop signs! There is one camera positioned at the sign leaving the lower parking lot, and there's another camera at the sign entering the upper parking lot. If they catch you rolling through a stop, you will get a ticket in the mail a week later for $125 and a video link of you rolling through the stop. It's sneaky business that they're doing, and Brad and I got a ticket the first time we visited the park a year ago. Please be careful!
Parking is $7, cash or check. You put your payment in an envelope and place it a locked box at the lot. Part of the envelope is detachable, so you display that portion on your dashboard.
Be safe and have fun!
