The area of the castle of Riolas covers 7 hectares. It is located in Haute Garonne, at the entrance of the Comminges country, very near of the Gers and Hautes Pyrenees departments, on the first fold of the Pyrenean foothills. Its dominant position gives an exclusive view of the mountain.
 
Real estate comprises, in addition to the Castle, a building called 'the manor house' which shelters two flats (still to restore) and a farm building consisted of sheds and a stable of time with 5 large boxes for horses. The 3 buildings enclose a recreation area primarily occupied by a large (6 m x 12 m) swimming pool surrounded by a nice wooden terrace of approximately 100 m ¬≤ terrace. A gazebo with a  spa
complete this set livened by flowers and roses bushes.
 
The park focuses on the natural and wild side and a herd of sheeps is involved in its maintenance. It includes many  hundred-year-old trees, lindens, ashes, chestnuts, oaks... surrounding a large pool, old fishing pool of the Castle. The park has unfortunately been devastated by a whirlwind on July 9th, 2002. It still carries many stigmas and much remains to be done for its restoration. To see, at the end of the summer, the esplanade of the Castle covers with dwarf cyclamens which are prolif√©ring in the park.
