I would also like to sync my iNaturalist database with my hikes to show what observations I made on each expedition. Same with my Merlin Bird ID database
I have GPX data and images from previous hikes before I started using AllTrails. I may try and find a way to upload them in some visual way — maybe embed a web GPX viewer of the files. Nonetheless, the AllTrails embedded activity data is super cool, so I will be tracking my future hikes with it going forward.
