For this adventure you'll want to make your way to Oak Creek Canyon off highway 89 in Arizona.

The GPS should get you there no problemo, my recommendation would be to look for a swimming hole upstream of Slide Rock State Park.

Now this adventure is a little bit of a hunt, as you're driving the canyon you will see the long lines of cars parked on the side of the road in a tiny narrow canyon (see photos for what I mean with car parking), but no humans to be found!

This is where it gets interesting, there is no "right way" to go about finding your swimming hole in Oak Creek Canyon, you'll simply want to do some investigating. We parked on the side of the canyon and found a culvert to get underneath the road leading us to a swimming spot just outside the edge of private property, (lucky us) so do be cautious - if you see no tress-passing signs, play it safe and keep looking. 

Once you find your spot you won't be disappointed, this is a well known venture in the area and popular with the college kids in Flagstaff, if you feel lost ask somebody, you'll find your way. Likely any route you choose will involve climbing down into the canyon, so real shoes are recommended.

Enjoy!
