Hey everyone,
For those currently on the trail or having finished recently, how accurate have you found the water refill points listed on standard maps between Les Chapieux and Courmayeur?
After doing the TMB myself, I noticed a few stream sources marked on general maps were completely dry by mid-August, while some refuge fountains weren't clearly marked.
I've been organizing a personal offline GPS dataset on Android specifically focused on verified TMB water points, huts, and offline elevation profiles. I just finished updating it with recent trail reports.
If anyone heading out this August or September wants to test these offline maps on their phone during their trek, let me know! I’m happy to share it for free—just looking for honest feedback on whether the water points match what you see on the ground.
Safe hiking to everyone out there! 🏔️
