Enjoyed my hike on H-3.  It's 3 miles long and, I believe, you gain elevation of about 630 feet.  I didn't think it would be as much of a challenge as it was since I often see families walking the trails when I drive by.  I was quite surprised to see the number of children hiking this trail, and doing well!  Start-em young!\nThe view is all residential but you can see about 23 miles away!\nI did see a couple of lizards while hiking but no other wildlife.  Easy parking and free.
