Grand Genève (English: Greater Geneva) is a local grouping of transnational cooperation [fr] (French: groupement local de coopération transfrontalière or GLCT), a public entity under Swiss law, in charge of organizing cooperation within the cross-border metropolitan area of Geneva (in particular metropolitan transports). The Grand Genève GLCT extends over Switzerland (entire Canton of Geneva and the canton of Vaud's entire Nyon District) and France (Pôle métropolitain du Genevois français  [fr], literally "Metropolitan hub of the French Genevan territory", a federation of eight French intercommunal councils in the departments of Ain and Haute-Savoie).

The Grand Genève GLCT covers a land area of 1,996 km (771 sq mi) (27.7% Swiss territory, 72.3% French territory) and had a population of 1,046,168 in Jan. 2021 (Swiss estimates and French census), 58.3% of them living on Swiss territory, and 41.7% on French territory.

Bresse (French pronunciation: [bʁɛs] ) is a former French province. It is located in the regions of Auvergne-Rhône-Alpes and Bourgogne-Franche-Comté of eastern France. The geographical term Bresse has two meanings: Bresse bourguignonne (or louhannaise), which is situated in the east of the department of Saône-et-Loire, and Bresse, which is located in the department of Ain. The corresponding adjective is bressan, and the inhabitants are Bressans.

Bresse extends from the Dombes on the south to the river Doubs on the north, and from the Saône eastwards to the Jura mountains, measuring some 100 kilometres (60 mi) in the former, and 30 kilometres (20 mi) in the latter direction. It is a plain varying from 180–240 metres (600–800 ft) above the sea, with few eminences and a slight inclination westwards. Heaths and coppice alternate with pastures and arable land; pools and marshes are numerous, especially in the north. Its chief rivers are the Veyle, the Reyssouze and the Seille, all tributaries of the Saône. The soil is gravelly clay but moderately fertile, and cattle-raising is largely carried on. The region is, however, more especially celebrated for its table poultry.

Isère (US: /iːˈzɛər/ ee-ZAIR; French: [izɛʁ] ; Arpitan: Isera; Occitan: Isèra, Occitan pronunciation: [iˈsɛɾa]) is a landlocked department in the southeastern French region of Auvergne-Rhône-Alpes. Named after the river Isère, it had a population of 1,271,166 in 2019. Its prefecture is Grenoble. It borders Rhône to the northwest, Ain to the north, Savoie to the east, Hautes-Alpes to the south, Drôme and Ardèche to the southwest and Loire to the west.

The GR 59 Grande Randonnée long-distance footpath in France connects two mountain ranges across relatively low-lying terrain. In the north, it begins at Ballon d'Alsace in the Vosges at a height of over 1000m. It loses height rapidly, and runs south-south-west through the département of the Haute-Saône to Besançon on the river Doubs, in the département of the same name. It then follows a circuitous route, partly along the river Loue (a tributary of the Doubs) to Lons-le-Saunier in the département of Jura. At St-Amour just south of Lons, the GR 9 splits from the GR 59 and takes a more easterly route, near the Swiss border, while the GR59 continues into the regions of Bugey and Revermont in the département of Ain, finally rejoining the GR 9 near Yenne on the banks of the Rhône; the GR 9 then continues to the Mediterranean at St-Tropez.

Towns and villages that the path passes through, with approximate heights and distances from the northern end of the path, include:

Fort l'Écluse, or the Fort de l'Écluse, is a military fort in Léaz, Ain, close to Collonges in Eastern France. It commands the Rhône Valley as a natural entrance into France from Switzerland between the Vuache and the Jura Mountains.

The fort, which was established by a Duke of Savoy, was completed by Sébastien Le Prestre de Vauban during the reign of King Louis XIV. It was destroyed by the Austrians in 1815, but rebuilt by the French; at the same time it was considerably strengthened and heightened. The high-road intersects a portion of this fortification.
