Croix-Rampau, Mountain summit in Poleymieux-au-Mont-d'Or, France.

Croix-Rampau is a mountain summit in the Monts d'Or range northwest of Lyon, rising about 464 meters above sea level. An orientation table at the top helps visitors identify distant views across the Alps, Dombes, Saône Valley, Beaujolais, and Bresse on clear days.

The site has been protected since 12 May 1941. The summit is marked by a white boundary stone, and near the top stand the ruins of a windmill tower where the physicist Ampère sometimes walked. A paragliding launch area was laid out on the site in 2009, managed by the Lyon free-flight club Taille-Vent.

The summit takes its name from a cross, though the white marker stone at the top is what visitors actually see today. The physicist André-Marie Ampère, who lived nearby, sometimes walked up here by the windmill; only the ruins of its tower remain.

The summit is reached on foot by a trail; the orientation table stands at the top, and the white boundary stone marks the highest point. The paragliding takeoff, added in 2009, is narrow and used only with north winds, so walkers should keep clear of it. Clear days reveal the Alps, the Dombes, the Saône valley, the Beaujolais and the Bresse.

The paragliding launch area set up in 2009 is managed by members of the Lyon free-flight club Taille-Vent. It works on north-sector wind and is narrow, so it is reserved for experienced pilots. The white marker stone at the summit is a separate detail to look for.
