It also has surprisingly detailed and complete hiking trails on it (for the Alps at least).

Openstreetmap sourced. Their android app windy maps is pretty good for hiking trails.

I didn't know that! Windys color scheme is a lot clearer (and I like you see hiking trail numbers on it) but OSM shows hiking refuges when more zoomed out.

It is based on mapy.cz [1] - Outdoor layer. It is mostly OSM based (plus lot of their own data for Czechia and Slovakia). Mapy.cz belongs to same guy, who runs Windy (Ivo Lukačovič [2]). IMHO it is best readable map on the internet and when I am used to it, I cant find anything on Google Maps.
