Get off on exit 25 but even if you don't remember that there is a sign that tells you how to get there. After you get off the exit just keep following the signs. When you get arrive there are signs posted that tell you to be aware of snakes but the signs make you more paranoid. I'm just glad I didn't see any. We got there at sunset and it was so pretty. I don't know why I was so excited about colorful rocks but it was just something neat to see.
