Yes, you can pay with a credit card at the Petra Visitor Center to purchase your entry tickets or your Jordan Pass in 2026. Major cards like Visa and Mastercard are widely accepted at the main gate and even in some of the larger gift shops and "luxury" cafes inside the site (like the Basin Restaurant). However, a supportive peer "cash is king" tip: as you go deeper into the Siq and toward the Monastery, most small Bedouin stalls selling tea, scarves, or donkey/camel rides are cash-only. In 2026, I highly recommend carrying at least 30–50 Jordanian Dinars (JOD) in small bills for these interactions. Also, be aware that "Petra by Night" tickets often require cash and are sold at a separate kiosk. While the "big" expenses can go on your card, the small, authentic experiences that make Petra special still rely on the local currency.
