Séguret is located at 250 m above sea level, beneath the Dentelles de Montmirail, a mountain range between the Rhone and Mont Ventoux. The town is located amidst vineyards and olive groves at the foot of a rugged hill occupied by a castle ruin. The village square offers a panorama of the Dentelles de Montmirail, the Vaison-la-Romaine plain and the Massif Central in the distance.
