Well, there are lots of different OSM maps. None of the five map layers on openstreetmap.org are designed as trail maps. Examples of ones that are are https://www.thunderforest.com/maps/outdoors/ and https://hiking.waymarkedtrails.org/, although each shows different features of the underlying data. Each of these maps (the two just mentioned, the five at osm.org, AllTrails, and lots of others, including the Mapbox ones you see in all sorts of places) are all “osm maps”, but they’re choosing to highlight different elements of the data. Unfortunately the AllTrails one doesn’t highlight information that I’d consider pretty essential for a trail map, such as “is this feature unmodified TIGER data and therefore may not actually exist” and also the quite important “am I actually allowed to walk down here”.
