Sat navs, Google maps, online and offline options - still, I like to carry a paper map as an ultimate fall-back if all else fails. This is a Michelin Regional series, no 504. For Angleterre, "South East" is interpreted so broadly that it includes Liverpool, Grimsby, and Weymouth. Lots of useful detail. Any other suggestions?
Prefer the A-Z books, got a van full of them for those inopertune moments when my Garmin, iPhone and Android fail me at work.
I favour OS Tour Map series - the blue ones. Not sure they're still printing them but you can still buy older editions. Ordnance Survey Tour Maps – ukmaps.co.uk They're brilliant for planning bike touring routes because they're massive but detailed physical maps that show full landscape features so you get a good idea of what the area you'll ride through will look like. I've planned rides throughout Scotland using one of these. It opens out about four foot square on a table and allows you to plot a route across a extensive area while still seeing all the detail. Unlike digital mapping apps which are like looking at the landscape through a letter box with detail disappearing as you zoom out. I find that disorientating. I'd far rather see the whole landscape in one go on a large paper map. I'd never be without one on a tour. I'll plot a ride using the paper map and then either load the route into my sat-nav using via points or simply follow hand written directions in the document window on top of my tank bag.
I bought one of these plastic ones. Using a map because I had not got round to fitting the sat nav. Heavy rain in Champagne-Ardenne was making map reading difficult - luckily came across one of these plastic ones in a shop.
I love looking at old maps and recently came across a website run by the National Library of Scotland. It has a facility to load two maps side by side. Recently I have be looking at a map from 1820 of England/Scotland/Wales alongside a modern satellite image. What is great is your cursor on the satellite image is reproduced on the older map. https://maps.nls.uk/os/
