Access to the commune is by the D86 road from Charmes-sur-Rhône in the north which passes through the commune and continues south to La Voulte-sur-Rhône. The D86E branches from the D86 at the northern communal border and goes to the town then continues south to rejoin the D86 at La Voulte-sur-Rhône. The D21 goes west from the town to Saint-Laurent-du-Pape. The east of the commune includes a portion of the Île Saint-Thimé in the Rhône river which is also the departmental border with Drôme. A railway line from Saint-Péray in the north to La Voulte-sur-Rhône in the south passes through the commune but there is no station in the commune. The commune consists of a large urban area along the banks of the Rhône with farmland south of the Eyrieux and forested hills for the rest. A branch of the Rhône forms the eastern border of the commune with the main branch flowing south through the commune and continuing to eventually joining the sea at Port-Saint-Louis-du-Rhone. The Eyrieux river flows through the commune from the west to join the Rhône just south of the commune. Numerous streams rise in the commune and flow south to feed the Eyrieux including the Ruiseeau de Thouac, the Ruisseau d'Abrou, and the Ruisseau de Chauvert. The Ruisseau de Feuillas flows east through the north of the commune to join the Rhône. There is a dam on the main branch of the Rhône with an electricity generating station: the Centrale Electrique de Beauchastel. Beauchastel was often the victim of floods of the Eyrieux, until the construction of a damin the upper reaches of the river in 1860.

History
The commune takes its name from the castle "Bel Castrum" built in the 12th century by the Lords of Retourtour and Briand. Since ravaged by the Wars of religion, all that remains is the fortified tower that dominates the village. In the 17th and 18th centuries Beauchastel was one of the Royal salt barns for the payment of the Gabelle of salt.
In 2012 the commune had 1,747 inhabitants. The evolution of the number of inhabitants is known from the population censuses conducted in the commune since 1793. From the 21st century, a census of communes with fewer than 10,000 inhabitants is held every five years, unlike larger communes that have a sample survey every year.
The Bellum Castrum Medieval village. In 1179 the first lords, Retourtour and Briand, built a tower and ramparts to defend against invaders. The medieval village is built on the site of the old castle. During the Wars of religion the village was destroyed in 1622 by order of Louis XIII and the fortifications of Beauchastel were levelled; the ramparts and the defence towers disappeared. Despite these demolitions the site retained its medieval aspect enriched by architectural elements from the Renaissance until the early 20th century.
The Ancient Castle dating back to the 12th century overlooks the village. It was limited to a protective Keep with a square base of which only a section of wall remains. It was destroyed together with the village during the wars of religion.
