Hiking in England/Scotland - Pennine Way

You might check into OSM maps for the area.

Thank you.  I just looked and they have the "Garmin GB TOPO PRO - GB v2 Full 25k, 50k, 250k," but that is about $460!

My bad - I was looking at the Ordinance Survey Maps (OSM) from England, not the Open Street Maps (OSM) you referenced.  I'll check those out.  Thanks again!

Hi, there's a very long delay in getting the openstreetmap.nl map at present.

Try https://alternativaslibres.org/en/index.php  I find these excellent.  Includes topo as well.  The service is exceptional too - I needed Mongolia for a motorcycling customer riding from Morocco to Vladivostok so paid 30 Euro and had a map a few days later. 

My fault. It is Great Britain - should have realized the possible confusion.

For the 66i, we are using maps from:

https://garmin.opentopomap.org

they are somewhat bigger in volume then other similar, but have lot of details and are also routable.
On the 66i, I have to select to show less details under normal operation. I have also tested to take 64GB card, format to FAT32 and fill it with those maps. Works perfect.

Thank you.  Are these downloadable to a Mac too (for the program data)?

those are just normal garmin  .img files, you can download them where ever you want. It is just a website where you can select them and download as any other files.

Thanks
