Mont Myon, Protected mountain summit in Courmangoux, France.

Mont Myon is a protected mountain summit near Courmangoux with sedimentary rock formations that create varied ecological zones for observing local plants and animals. The site is designated as a natural area of ecological interest, protecting both its landscape and wildlife habitats.

Mont Myon belongs to the Revermont, the limestone foothills of the Jura in the Ain department near the border with the Jura department. The summit and its western face are made of Bajocian limestones with crinoid and coral remains, while the eastern face consists of ferruginous oolitic limestones from the end of the Lias and the beginning of the Dogger. The site is a classified natural site and a ZNIEFF.

The summit's orientation table identifies the ridges of the Revermont and the surrounding Jura reliefs. The site is also a paragliding launch point listed by the French Free Flight Federation, so walkers often watch pilots take off from the open slopes.

The GR 59 long-distance footpath crosses the summit, where an orientation table stands; the climb is on marked trails from the surrounding villages of Val-Revermont and Courmangoux. The upper slopes are open grassland, so carry water and sun protection, and check the weather before setting out, as the ridge offers little shelter.

Mont Myon is a paragliding launch site listed by the Fédération française de vol libre. The cleared slopes of the summit and its west face allow pilots to take off and gain height above the Revermont. The GR 59 long-distance footpath crosses the summit, so walkers share the ridge with the pilots.
