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 would maybe check out Hiking project if your in North America. It looks really similar to all trails, except you have to download particular areas. The drawback is that the user input is almost nonexistent on smaller, local trails. More popular trails have some good info though. This definitely seems like it has promise.
Then theres Farout (formerly guthook) - I’ve heard this app mentioned alot as the preferred way to navigate trails like the AP or CDT. It costs money, and it’s not cheap, but you can download the app and continue as a guest and check put some of the free maps they provide.
Second vote for hiking project.
I think it just matters where you live. I’m in the PNW and it has a ton of info on the local trails around me. Love that its offline too.
