If you've had enough sunbathing or swimming for the day, there are plenty of sights to see in Tunisia, many of great historical or cultural significance. The capital, Tunis, is home to the remains of the ancient city of Carthage, not to mention a host of mosques and souks or local markets.
The Roman ruins at Dougga and El Djem, particularly the Colosseum at the latter, provide a fascinating insight into what life was once like in the area. And the country should excite film buffs: classics such as The Life of Brian, Star Wars and Raiders of the Lost Ark were filmed in the area.
Aside from the beaches and Roman ruins, there is plenty worth setting a day aside for in Tunisia. The port of Bizerte, Tunisia's oldest city is worth a visit, especially its Old Town, which is littered with cafes and shops. Fans of Star Wars, meanwhile, will be interested in a trip to Matmata, where the opening scenes of the film were shot.
While the Sahara may not seem like an obvious tourist attraction, the vast swathes of sand - the desert covers an area almost as large as the USA - are quite breathtaking in person, a real sight to behold. And once you're there, you can actually be quite adventurous, if you're in the mood: activities on offer include quad-biking, sand-surfing and camel trekking.
