L'Atol Beach, Lac des Eaux Bleues

L'Atol Beach is the main paid, supervised sand beach of the Grand Parc Miribel Jonage, a large park of lakes and woodland on the Rhone floodplain east of Lyon in the Auvergne-Rhone-Alpes region of France. The beach sits on the Lac des Eaux Bleues, a man-made lake created from former gravel pits, and is reached from Chemin de la Bletta in Vaulx-en-Velin, about 12 km from central Lyon. The shore is laid with sand rather than pebbles, and the lake water is fresh, usually green-blue in colour, and noticeably cooler than the air even in midsummer. Because it is an enclosed lake there is no surf or tide; the swimming area is marked out and watched by lifeguards, which makes the setting calm and suited to children and casual swimmers. Among the park's four beaches, L'Atol has the longest summer opening hours, and entry is charged: adults pay roughly EUR 5-8.50, children aged 4-11 about EUR 2.50-4, and children under 4 enter free, with prices varying by arrival time. The ticket covers access to a managed leisure base with toilets, showers and changing rooms, snack bars and restaurants, and hire of pedalos, paddleboards and kayaks. The atmosphere is that of a busy urban-fringe lido: families, groups of friends and school or holiday-camp parties fill the sand on hot weekends, and the car parks can be full by early afternoon in July and August. Access is varied. Cyclists can follow the park's paths from the Parc de la Tete d'Or in about an hour, a summer Echappees Nature bus runs from Lyon (current dates are published at grand-parc.fr), and drivers use the park car parks. The season is short, running from late June to early September, when supervised swimming is in operation; outside those weeks the lake is not patrolled and swimming is not advised. Visitors wanting a quieter lake day often choose the free beaches elsewhere in the park, but L'Atol is the most complete option for facilities.
