Wupatki National Monument

You would drive and park. Walking to the site from small parking area is approx. Less than 1/4 of a mile. It is not a long walk at all.

Actually, dogs are not allowed on the trails or natural areas. Some national parks allow dog on a 6 ft leash but due to fragile archeology, plants, and wildlife, pets are not allowed beyond the parking lots. https://www.nps.gov/wupa/planyourvisit/pets.htm As far as "canine discrimination" it's actually the NPS following it's legal mandate to protect "the wild life therein" and choosing local animals over visiting ones. There are some awesome doggie day care and kennels in Flagstaff and at Grand Canyon South Rim. Many folks bring their pets with multiple humans and take turns walking the trails with someone staying with the pet in the parking lot. If youre traveling solo with Fido, consider making a friend with another visitor who would be willing to hang out with your pup for a bit. May take a few tries to find the one, but I bet it's easier than dating these days! Please bring your own bags for dog waste (and pack them out--there are trash cans at the Visitor Centers parking lots).

Yes. Although which direction the air flows depends on air pressure. Sometimes it sucks air in rather than blowing it out.

Yes, and it's more extensive than many other similar places, such as the cliff dwellings near Durango.

We visited on Tuesday 5/4/21 and it was free.

Not above any NPS lands, not above Wilderness. You can Google the NPS rule but here's a good article. https://pilotinstitute.com/can-i-fly-my-drone-in-a-national-park/ It's allowed over the Forest Service land but it is up to the operator to know the boundaries and abide. And not allowed over Forest if there is an incident such as a fire or search and rescue.

No, it does not. It is covered under the annual America The Beautiful pass, though.

No, there are no campsites in Wupatki National Monument (elevation 4500 ft). We recommend the Bonito Campground at the entrance to Sunset Crater Volcano national monument (elevation 7500 ft) There is no BLM land nearby. There is USFS land south of the Monument near Strawberry Crater. One road is a good dirt road from hwy 89 (when conditions are dry). The other road, which your GPS may tell you is shorter, is soft cinders which is like driving in sand which I do not recommend.

When barometric pressure is rising it pushes cold air out of the vent like an air conditioner. When barometric pressure is falling, no wind from the hole. It's a natural phenomenon, not man made, and the underground caverns causing the rush of cold air are not accessible. The cold air comes out strong enough to blow a hat 10-15 feet in the air when you let it go over the vent. Quite amazing and one of the most memorable and surprising things discovered on our trip out west.
