The municipality of Gassin is located in the center of the peninsula of Saint-Tropez, from which it is distant of only 4.9 miles (7.9 km) by a departmental road. It has undergone a development strongly marked by tourism since the second half of the 20th century. While the medieval village implanted on a hill 659 ft (201 m) above sea level has little changed, hamlets have developed in the plain. The Foux crossroads and the seaside leading eastward towards Saint-Tropez have also experienced urbanization and welcome large tourist complexes in the heart of wooded parks.
