This is our second time visiting Jack's Creek in a 6 year span.
Let's start with the perks: it's gorgeous. Towering ponderosa pines, spruces and aspen trees, with ample meadow spaces. The camp sites are large and not crammed together. It's remote (I'm counting that as a perk) and really off the grid - there is no cell service whatsoever here. It's peaceful for the most part: hummingbird's galore, deer meandering through camp, birds to watch and a night sky that is lovely and awe inspiring.  Please, for the love, do not feed the stupid chipmunks - they are not afraid of people and it shows.

The downsides: the road is one lane in some places getting up there. Please everyone just slow down and use good sense (i.e. do not crowd someone's tail going up or down the road.)
There is no longer any potable drinking water at Jack's Creek. Haul your own in. I heard other campers lamenting this...but it's just a fact of life that drilling and maintaining a well at nearly 9K feet above sea level is an arduous task.
Another downside: no camp host this time around...means no one to help remind other's of the rules. For example: a dog off leash who was a tad aggressive, running through other sites  - I did NOT want to turn my back to that mutt. And a generator that didn't shut off until 10:30pm at night. But all in all, the pros out weigh the cons for this gem of a spot in New Mexico.

If you are caravaning with two vehicles...or have a small pop up with vehicle and don't mind paying for 2 spots - we absolutely love the 35/36 site shared spot. No one to the South, and the tall trees provide shade for your tent in the morning or chairs in the heat of the afternoon, to the west. Snag it if you can, but note it will not work if you are towing a large 5th wheel.
