Traveling in Chandler, AZ. I saw this at my sisters house. What kind of cactus is this?

Looks like a Cereus, maybe this one. Edible fruit in summer.

Thanks for getting back so quickly. I appreciate it. Here are more pictures if anyone is interested.

Very attractive plant!

Peruvian apple (Cereus repandus) is a spectacular columnar cactus with gorgeous flowers and attractive, edible fruit which people eilther seem to either love or hate. I've heard it described as tasting like everything from vanilla sorbet (yum!) to slimy okra (yuck). You can learn more about it here: https://swgardener.com/peruvia...
