Description

I’ve been using US Topo Maps for a couple months now. It’s basically an app that gives you free access to all kinds of detailed maps and imagery for the whole US. So whether you’re planning a hike, a camping trip, or just want to explore some new areas, this app’s got you covered.

There’s over 30 different map layers you can choose from – things like topographic maps, aerial photos, nautical charts, and elevation data. It’s super handy for things like plotting your route, finding good campsites, or checking trail conditions before you head out. The maps download for offline use too, so you don’t need cell service when you’re out in the boonies.

Look, if you’re an outdoorsy person who likes to explore new places, you’ll probably really dig this app. It’s not perfect – the interface can be a little clunky at times – but overall it does a great job of giving you all the mapping tools you need for your adventures. Definitely worth checking out.

Editor Opinion

I've tested a bunch of different navigation and map apps, and US Topo Maps is one of the better ones I've come across. The sheer number of map layers and data sources they have access to is really impressive, and the offline capabilities are super useful. And in my experience, the app is generally pretty easy to use, though the UI can feel a bit cluttered at times. But the tradeoff is that you get a ton of functionality packed in. If you're an avid hiker, camper, or just love exploring the outdoors, this is definitely an app worth having in your toolkit.

I use this more than OpenCPN for navigation as it allows me to save and use offline charts more intuitively (late 2025). Once Dave gets OpenCPN to function better maybe...
