Getting lost in the backcountry isn’t just annoying — it can be dangerous. Reliable GPS devices and hiking apps are no longer “nice to have.” They’re gear you absolutely need when you step off paved trails and into the wild.
Today’s best hiking apps and GPS tools go way beyond simple navigation. They show trailheads, track elevation, store offline maps, and even drop waypoints for emergencies. In other words, they can turn your phone into a full-on survival tool. They also help you plan your route before you leave. They help you reroute if a river, storm, or closed trail blocks your path.
Whether you’re a casual hiker chasing day hikes or a thru-hiker trekking 2,000 miles, having the right app can mean the difference between a great adventure and a bad story. Let’s break down the top choices — the ones built to handle real miles, real weather, and real backcountry navigation needs.
Top GPS Apps for Hikers: Navigate Any Trail with Confidence
1. Gaia GPS: Gaia GPS is a favorite for serious hikers who want detail and reliability. It offers high-quality topo maps, satellite imagery, and offline layers that work deep in the backcountry. You can customize your maps with layers like cell coverage, slope angle shading, or wildfire history. It’s great for thru-hikers, climbers, and anyone needing deep map control. Easy downloads, smart layering, and reliable offline use make it a true trail essential.
2. AllTrails: If you love finding new trails and want easy planning, AllTrails is a top choice. The app offers a massive database of hikes worldwide, complete with user reviews, photos, and trail ratings. You can filter by difficulty, length, and activity type. The Pro version unlocks offline maps, wrong-turn alerts, and custom route building. It’s perfect for weekend hikers, families, and travelers who want options without the stress.
3. OnX Backcountry: OnX Backcountry is built for hikers who don’t always stay on marked trails. It’s packed with layers for public/private land boundaries, detailed property info, and hunt-specific features if needed. 3D mapping gives you a better idea of terrain before you ever leave home. Offline access is strong, and route tracking works great even far from signal. If you explore remote areas or like planning off-trail trips, OnX gives you serious backcountry navigation tools.
4. Caltopo: Caltopo started as a mapmaker’s dream and turned into one of the most powerful tools for serious outdoor planning. It shines for building custom routes, managing emergency scenarios, and layering maps with avalanche data, slope angles, or public land grids. Offline features are strong once maps are downloaded. Caltopo is a bit more technical than others, but if you love planning detailed trips and customizing your maps, it’s worth every second.
GPS Watches You Can Trust When the Trail Gets Tough

Caltopo vs Gaia GPS: Which Mapping App Wins for Serious Hikers?
This matchup is a heavyweight battle. Both Caltopo and Gaia GPS are incredible for serious hikers, but they serve slightly different needs.
Gaia is famous for its polished user experience, super detailed layering, and plug-and-play ease. It’s fast to download maps. It’s easy to toggle between satellite, topo, and trail overlays. It works great for solo weekenders and thru-hikers alike.
Caltopo, on the other hand, feels more raw and technical. It’s made for planners who love drawing custom routes, measuring avalanche slopes, and digging into emergency scenarios. Caltopo shines for mountaineering, backcountry skiing, and SAR operations.
If you want a hiking app that’s ready to roll with zero learning curve, Gaia is it. If you love deep map customization and don’t mind a steeper learning curve, Caltopo might be your new favorite tool.
OnX vs AllTrails: Which App is Best for Your Hiking Style?
Both OnX and AllTrails are giant names in the hiking world, but they serve slightly different crowds.
AllTrails is the king of trail discovery. If you want to find trails fast, read reviews, and download simple maps, it’s hard to beat. Its clean interface and huge trail library are user-friendly for beginners and casual weekend warriors.
OnX Backcountry is the tool for people who leave the marked trails behind. It shines with public/private land data, hunting overlays, 3D maps, and detailed offline features. If you’re into exploring lesser-known trails, bushwhacking, or hunting areas, OnX fits better.
Ask yourself: Do I mostly hike well-known trails and want crowdsourced info? Pick AllTrails. Do I venture into less managed wild areas? Choose OnX. Either way, these two apps have made hiking safer and smarter for millions of adventurers.
Good Navigation Isn’t Optional
Gone are the days when hikers could just stuff a paper map into their back pocket and hope for the best. Trails split. Weather changes. Phones lose service. When you’re deep in it, good navigation isn’t just nice — it’s necessary.
Reliable hiking apps and GPS tools aren’t about adding gadgets to your trip. They’re about giving you freedom. Freedom to explore new trails without fear, freedom to change plans on the fly when nature decides not to cooperate and freedom to go deeper into the outdoors, not just circle parking lot loops.
Spend a little time now finding the app or device that fits your style. A few extra minutes setting up offline maps can save you hours of frustration, or worse. Good navigation doesn’t just keep you on track — it opens up the whole world for you.
