Going to be in Aqaba Jordan for three days in October. Would appreciate tips about things to do and see in the town and nearby vicinity, especially cooking, markets, art, culture, etc.
So I would suggest you get out on the Red Sea and snorkel or dive. The Red Sea is known around the world for diving. There are some cool artificial reefs just off shore as well.
There are lots of places to eat in Aqaba most of my favorites are listed in the link.
After one day, I suggest you plan a daytrip - either Petra, Wadi Rum, or the Dead Sea. You can rent a car and drive, or take a tour.
When you arrive, you will notice how small the town is. There is one main market, near the water. There is one main area for hotels and restaurants etc. There is a Friday evening market near Captain’s hotel as well.
