This was a good hike but my mistake was trying to follow the previous map. This is a big park with many trails - some are marked well and others not so well. They are used alot by mountain bikers so they really go all over the place. I even found the marking posts confusing. Finally said "to heck with it" and just followed the trails we happened upon.
Other than that, I would go back there again and forge my own hike.
