Another popular way to navigate is using GPS recordings of hiking routes (GPX format). There are many web sites / databases from which you can download thousands of GPS logs of existing hiking routes:

https://hiking.waymarkedtrails.org/ (already present in OSM)
https://www.wikiloc.com/ (mostly touristic routes)
https://www.ramblr.com/ (popular in the Sahyadri)
https://www.strava.com/ (running, hiking, cycling routes)
https://www.openstreetmap.org (uploaded GPS traces)
Many hiking blogs share hiking logs

For example, let's search and download a GPS log for say "Kedarkanta" and import the same into OSMAnd for additional analysis / routing. Open "wikiloc.com" on your mobile or laptop, search and download the GPS log for any Kedarkanta hike listed.
