And even if I organized a hike to Big Sur, Apple Maps would be pretty worthless because it doesn't have trail visualization and navigation worth speaking of (ok, maybe in Big Sur, but certainly not the rest of the world).

So I end up pulling out the trusty old Garmin gpsmap with cycle/hiking maps, that survived drops from 1.5 meters at 30 km/h as I was gliding of a mountain with my bike.

I recommend mapy.com (mobile app and web app too when on computer) - they mostly use OSM data and rendering of map tiles is great. Also offline maps etc.

There are several great options, besides mapy, e.g. Organic Maps and CoMaps also work pretty great. There are also some really good bike optimized apps (like NodeMapp for the Dutch cycle network).

But I generally prefer to use a Garmin GPS or watch. They work for days without charging (the older models even work with two AA batteries), very robust (e.g. their gpsr survives drops), work well offline, and transflective displays work better in direct sunlight.

For planned routes, I make then in NodeMapp or some other focused application and send the GPX overs to a gpsmap unit or Fenix watch. Many national parks, etc. also have great GPX files for recommended hiking/cycling routes.
