Recently, I’ve started using GPSBabel and Ramblr together to better visualize and scout new hikes. GPSBabel is this fabulous tool that lets you combine various gpx files into one and Ramblr lets you plan and chalk out your trips. Both tools obviously have a ton of more features which I should explore at some point in time.
While on the trails, the AllTrails app is a terrific companion. Having a birds-eye view is always helpful and it’s never quite failed me!
