I am not sure if entry fee is waived. If you Can check on line with the park service. I know the Grand Canyon will be waving fee for veterans day

Get there at sunrise and you won’t have to pay anything. We drove through the entire park for free. We even spoke with one of the park rangers who told us as long as you’re there before 9 AM you don’t have to pay anything because they are not open yet. There was also hardly anyone there that early and we almost had the entire place to ourselves!

Part of NPS TOURS AND CAMPING One fee covers entrance to both Sunset Crater Volcano National Monument and Wupatki National Monument for seven days. Annual passes for Flagstaff Area National Monuments are also available. While there is no camping at Sunset Crater Volcano National Monument, the Bonito Campground, operated by the US Forest Service, is located across from the visitor center at Sunset Crater Volcano National Monument. The campground is usually open between late May through mid-October.

The crater site itself has a handicapped access short overlook walkout about 50 yards maybe? The pueblos are a distance from the parking lots but the largest has a close-up information center well worth the visit.

You do not need a guide or tour. Ranger will give you a map and all information is not that as well as "markers" at the stop off points.

No. It is protected. Since 1973. If you hike O'Leary's Peak Trail, you can see down into Sunset Crater.

There are multiple possible paths and loops, some of which you can string together, so you need to take some time at the visitor center and plan out what you want to do.

I would also suggest you have a picnic on site. It slows you down and makes you better appreciate the scenery.

Depends on whether it has snowed. The National Park doesn't have the staff to clear roads quickly. 4x4? No worries then. Always call ahead when in doubt. Just like any other area that gets a little snow, slushy, icey, but beautiful with all the snow around the black rock. If you do the loop, with the Indian ruins, it will be red rock with snow. It's a great drive!

I am not familiar with Dinosaur Tracks or its location, but my family did Walnut Canyon (don't miss!), Sunset Crater and Wupatki plus Lava River Cave all in one great busy day. We did not do a lot of hiking at Sunset Crater, however- only did the shorter level trail. I guess it depends on how much time you want to spend at each.
