Spain is a huge country. Food is excellent- often tapas a very good snack. People very friendly, but almost no English spoken at least where I went. Mountains everywhere.
There are almost no bicycle paths except a patchy Eurovelo 8 sometimes along the coast up to Valencia. Cities have bicycle lanes that are sometimes very good, sometimes confusing, and are dominated now by the ubiquitous electric scooter that is silent and fast. Barcelona in particular with constant stoplights was not fun.
I most often used maps.me on this trip for planning and navigation. Google maps as always is good, but the bicycle routing feature (available in some countries) is not an off-line feature. With maps.me it is.
Komoot I used in Cordoba to find good cycling routes outside the city and it has some features that I sometimes used in route planning.
Spain just has too many cars and too many aggressive drivers. I guess probably not much different from France.
