I don't understand why Mont Chaix (Lalouvesc, Ardeche, France) is not a #SOTA spot. It could be a 2 points summit.
#SOTA is rather restrictive which summits they admit to the program. If you know a summit they have not, one option you (almost always) have: Enter that summit into the #GMA program https://cqgma.org/ instead.
One of several things I love about GMA: THIS YOU CAN DO YOURSELF, once you have an account!
The moment that's done, you can put your rig into your backpack and your feet into your boots and be off for a fun activation!
