One of Phoenix's most underrated trails. The trail is smooth, the Wind Cave is a great place to rest and see animals, and there's even a bonus section if you're willing to take a little risk. Easily worth the $6 park entry fee, especially if you go early or in the middle of the week. Found a pretty good detailed break down of the trail here. http://www.fuistetravels.com/wanderings/windcavetrail
