This site would display the same sort of information as All Trails: descriptions, pictures, waypoints, information about trail dangers, trail maps, time to complete the trail, distance, elevation gain, hiking season, etc.
I apologize if this is not the right community for this post. If there is a more appropriate community, please let me know, and I will repost this there.
I believe there is! Have you tried https://hiking.waymarkedtrails.org you just zoom somewhere and it will show you available trails.
+1, I use waymarked trails, combined with https://brouter.m11n.de/ (which can show the trails) to get distances and elevation.
Thanks that is great find
