In the island's southeast, between Midoun and Aghir, stretches one of Djerba's longest ribbons of fine sand. Less built up than the Sidi Mahrez hotel zone further north, this stretch of coast charms with its calm, wind-sheltered waters and its wide-open spaces that still feel breathable even in high season. It's also the area where several 4- and 5-star hotel complexes cluster, well suited to gentle water sports — paddleboarding, canoeing, jet-skiing — and long walks by the water. Here is our complete guide to the two flagship beaches of this area, Seguia and Aghir, to help you choose according to the vibe you're after.
Seguia Beach
Tucked between Aghir and Ras Lalla Hadria, Seguia beach unrolls about 800 metres of fine sand facing calm turquoise water, just breezy enough to please windsurfing and water-sports fans. It's a wilder, less crowded beach than the large hotel beaches of Sidi Mahrès, valued for its sunsets and long walks by the water. A few restaurants and beach cafés sit nearby, some known for traditional Tunisian cuisine — and it's also very close by, towards the blue lagoon, that the camel rides offered in the area come to an end. The sea itself is beautiful and well kept, but several visitors report litter on some public access points and along the surrounding shore, notably near the former, now-abandoned Club Med. Better to favour access via the hotels or beach establishments if you want to avoid this, and keep your eyes on the open sea: that, at least, lives up to its reputation.

Aghir Beach
A little further south, Aghir beach gives its name to the whole area and likewise unrolls several kilometres of fine sand along the island's southeast coast. Its waters, even more sheltered from the wind than those of Sidi Mahrez, make it a very good spot for families and gentle activities like paddleboarding or canoeing, while jet-skiing and boat trips are offered by several water-sports bases along the shore. It's also the beach bordering numerous 4- and 5-star hotel complexes, and an area where dolphins are sometimes spotted offshore — a nice bonus for early risers. Regularly cited among the island's most recommended beaches in recent guides, it nonetheless remains freely accessible to everyone, hotel guest or not, making it a good option for a beach afternoon without booking an all-inclusive stay in the area.
Good to know for enjoying the southern beaches
As both beaches face east and are relatively sheltered, they suit families with children and fans of gentle water sports particularly well, unlike more wind-exposed spots. Access is free along their entire length, with sunbeds and parasols for hire in some sections. If you're after more buzz and more intense water sports (jet-ski, parasailing), the Sidi Mahrez area further north, in Midoun, remains the island's reference; for peace and quiet and sunsets, Seguia and Aghir have the edge.
