Monastir is an excellent base for a beach vacation with opportunities to make a really active one: water sports, excursions (Kairouan is only 80 miles) and golf.
Like all museums in Tunisia remember is closed on Mondays and open otherwise permanently from 9-18. Tickets not exceed one shilling per person plus another shilling for the right to take photos or shoot.
Hotels and alternatives
Monastir has plenty of hotels, but almost all are expensive, and aimed at package tourists. There are only a few budget options, as well as a youth hostel.
Restaurants and alternatives
Similar to hotels, there are few options for hungry budget travellers. People with more money to spend, will have more options, but in general Monastir is town where many tourists eat in the hotel.
Nightlife
Fairly good, if you go to the hotels. Here your options will include bars and Western style discos.
