GPS tracking devices

Hey gang. I am planning on buying a GPS tracking device such as the Garmin GPSMAP 66SR or the Garmin inReach Explorer+.
What I've been trying to figure out is with the Garmin pre loaded maps (topo maps and Earthmate) if any of these GPS tracking devices can find any hikes that All Trails has? Can a Garmin find the names of local hikes so I know if I'm headed of course? So I can download a common hike found on All Trails and use the Garmin to follow the map.

Thanks for any advice,
Ryan
