The main gateway into the country is Queen Alia Airport, 35km south of Amman. Most nationalities can purchase a one-month tourist visa on arrival. Passports need to have at least six months validity upon entry.
The best way to explore Jordan is to rent a car. Jordanian roads are well-maintained and well-signposted, making this one of the easiest countries in the Middle East to self-drive. Jordan’s public transport system consists of a ragtag collection of buses and shared taxis that run, mostly, to no fixed schedule. Fares are cheap and as long as you’re not in a rush, it’s fairly efficient for trips between the bigger centers. In some regions, though, public transport is severely limited, meaning you have to hire a private taxi to fill in the gaps.
