    I recommend the following maps for Tour du Mont Blanc:


    French IGN Topo
    Gaia Topo
    Satellite with Labels

    You will be able to download the Gaia Topo and Satellite with Labels map for offline use with a Gaia GPS Membership. While the French IGN Topo map comes with a Premium Membership.

    You can learn more about memberships here: https://www.gaiagps.com/membership/

    I purchased the premium membership however I am unable to access the French IGN Topo with the TMB shown on it. I have called and emailed GAIA GPS with no luck. I leave 8/27 for the hike and really would like to download the maps needed for offline use. Please advise how to access the correct maps and find the TMB on the maps with the premium membership.

    Yes, you need to click on the  Map Sources icon at the top (looks like several square of paper on top of each other), then click Edit, then select Europe, then scroll down to Premium if you want the France IGN Topo (you would need a Premium membership) and select France IGN Topo and click Add.

    I also selected the Swiss Topo for the one section in Switzerland that is not on the Franc IGN Topo.

    Once I had all the maps added, I then went back to Map Sources and turned on Layered Maps (scroll to the bottom of the list - another Premium option). Back at the top of the list under Maps, I made sure I had the Swiss, France, Satellite, and Gaia tops all under the Active section and then adjusted the slider bars to determine which maps were at the highest level and the most detailed level.

    Then I went under the + (with a circle around it) at the top of the App next to Map Source, and selected Download Maps. I found that I could not just select the large area of the TMB (maybe you will have more luck than I did) so I just selected smaller portions one after the other to connect all the parts of the trail. 

    The app worked really well on the trail and I was able to turn location services on for the entire day and track our route, saving each day's travel as a separate entry under the TMB folder I created within the app. For the saved daily routes, I also selected one unique color to "track" our progress, so I could the circle as we went around the massif. I also liked that I could track our elevations galns/losses as we were progressing each day. Great app for this hike!

    To verify your maps are ready for offline use, use these instructions from Gaia:

    Verify Map is Downloaded and Available Offline

    Follow

    Map downloads require the app to remain in the foreground. For this reason, we suggest plugging your device in and leaving the download to run overnight for larger map selections.

    If Auto-resume is turned off in the Gaia GPS settings and a download gets interrupted for any reason (like navigating away from the app), you'll see the option to "Resume Download" under "Load in Main Map" on the map details screen--this means your map download is incomplete. 

    Testing downloaded maps that do not offer an option to Resume Download:

    1. Disable Wifi  and Activate airplane mode on your device to disable cell access (GPS still works in Airplane mode after iOS 8.4)
    2. Open the app > tap Settings > Storage > Clear Cache > select 'OK' when the pop-up Warning appears.  
    3. Then open your map download on the Main Map by tapping Saved > your downloaded map > the 3 circle icon >Show on Main Map.

    Your downloaded tiles will show clearly and the surrounding area will be blank or blurry.

    Have a great hike!

    Thank you so much for the thorough answer!! This is great. It is sounding like this will give me a generalized map of the whole area, but it will not show a route to follow? I usually download the hiking trail route itself too, it shows over the topo maps as a little red line so I know I’m still on-trail. When I search the TMB it pulls up all these small section hikes and variants but not the entire traditional route. Although I think I found a .gpx file on the internet that I can download and then upload to the app.

    Glad to hear you’re out there right now too, I was worried I picked too cold a time to go and now there’s the glacier evacuation, but sounds like conditions are still safe for us. Hope you have a great hike too!!!

    Actually, we finished on  9 September. We had snow on 8 September, so hopefully you won't have too much wet weather. The trail is high up across from the area where the glacier is sliding so fast, so even if you are on the trail and something happens, you will be fine.

    The France map shows the trail very clearly and it is labeled. You will also see the variant trails. So I put the France map as the primary level of map for layering, so I could always see the general route, then used the other maps for more details on the topography. I had downloaded .gpx file that someone has posted, but I was not able to figure out how to use that within the app once I imported it.

    Once you download the maps and check offline, you will see the magenta colored GR TMB trail. I just added my own color to my tracks so that I could see our progress.
