camel tour
Go on a camal tour. One reputable operator is Amara Themri tel +216 97280133 / 23 131 483.
As always, pay for a one-hour tour before you embark on a multi-day tour if you have never ridden a camel before.
hammam
Enjoy the Hammam. Hours vary, as the local Hammams accomodate both men and women in a single Hammam, though not at the same time.
Hammam Shabia is recommended, and is just north of Hotel/Residence El-Amen. Bring your own towel and soap, and bathing suit, as people wear this or their underwear in the Hammam. 2-3 dinar for the Hammam, and 2-4 dinar for a massage, though the 'tourist tax' may raise this price to about 8 dinar total for everything.
