Yes, you absolutely need a ticket to enter the Petra Archaeological Park in Jordan. As of 2026, a one-day ticket for "accommodated visitors" (those staying at least one night in Jordan) costs 50 JD (approx. $70 USD). If you are a "non-accommodated visitor" (a day-tripper from Israel or a cruise passenger), the price jumps significantly to 90 JD ($127 USD). A highly recommended option for 2026 travelers is the Jordan Pass, which must be purchased online before arrival; it includes the Petra entry fee and waives the cost of the tourist visa, provided you stay in Jordan for at least three nights. Tickets are checked at the main Visitor Center in Wadi Musa before you enter the Siq. It is important to note that the "Petra by Night" experience—where the Treasury is lit by thousands of candles—requires a separate ticket (17 JD) and cannot be accessed with a standard daytime pass or the Jordan Pass.
