What's New in Version 2.0.8

We've added a number of new trails, including ones that lead to fantastic spots for catching August's solar eclipse. Daniel wrote in and requested trails in Shenandoah National Park so we added a slew of trails there as well.

If you're enjoying Cairn, think about leaving us a review. Happy trails!

Customer Reviews

Love this app

I use this app on every hike. It makes it easy for me tell people where I am going and has great topo maps.

Download the map before you go so you always have a map no matter how remote your destination. I love this feature.

I also value the ETA - it helps a lot with the planning and keeps the kids happy on the trail too.

Genius Idea

This is the best hiking app ever and probably my most useful app! It makes me feel much safer while hiking and being in remote areas, thank you!
