So my first destination from the airport was to a town called Jerash. It’s about 50km north of Amman and the drive from the airport was just a bit over an hour (made a stop to grab some supplies). Jerash is one of the better preserved roman ruins from about 300AD. Entrance fee to Jerash is 8JD, remember to buy some water before you go in. The sight is quite big so you can spend a good 2-3 hours exploring. There are guides which you can hire once you instead, and depending on your negotiation skills it can be 30-50JD. A few mentionable sites to visit would be The Forum, Zeus Temple, South Theater & Propylaeum. If you are hungry, I recommend to head back to Amman but if you want to grab a bite there is a shop outside where you can grab like a kebab.
