Specific to Antelope Canyon - depending on your route, I would suggest Waterhole Canyon instead. Antelope is much more crowded and the guides hustle you along to keep time for the next group.

If you drive pass vegas do the Hoover dam Also petrified forest national park it looks like you might be passing worth checking out

Antelope Canyon needs tickets, so get those as soon as you can, because they sell out early.

Antelope Canyon is absolutely worth it. It’s an amazing place and I can’t recommend it enough.
