The Coolest Places Around the World From Where You Can Mail a Letter | Condé Nast Traveler

"I observed that mail bound for Supai Village at the bottom of the Grand Canyon is still delivered by mule: six days a week, teams of 10 to 22 mules carry mail, food and supplies down a 9‑mile trail (about three hours downhill and five hours back up), with each mule carrying up to nearly 200 pounds balanced on each side. The return sees wranglers untether the mules so they can navigate the trail independently; the post office issues a special Mule Train postmark and remains the last official mail‑by‑mule route in the United States." - Zara Flavia Dmello

I had a smooth experience purchasing stamps at this location, which I used to send my postcards. They accept credit cards, and the stamps were priced at the standard rate of $0.68 for domestic mailing. If you're looking to buy postcards, you won't find them here. You'll need to visit the souvenir shop in another building. However, be aware that the postcards are quite pricey, costing $5 each.

Very Helpful, I accidentally put the wrong addresses on my daughters two packages I sent from Wisconsin. I called the post office and talked to a super helpful lady Coleen??. The two packages were going to be sent to the hill top the next day and delivered to her camp. Very polite and helpful. Thank you Supai Post Office

Just when you think a post office could not get any worse. They do not want to mail your mail!!! Bring stamps with you because they’ll never be open to sell you any and the store next door won’t sell them. This way you can put them in the mail slot for whenever they might decide to be open. Post cards are $1.89 each at the store next door. May want to bring those too. But either way I highly doubt you’ll get them mailed.

I have never had an issue with this post office. All of the workers I’ve encountered are very friendly. Keep up the good work, Supai Post Office!

How do I contact the person over the supai post office? To put it mildly, the service is not good here.
