Best Hiking Apps 2026: AllTrails vs Gaia GPS vs CalTopo

Why You Need a Dedicated Hiking App

Google Maps and Apple Maps cover roads well but trail data is sparse, inaccurate, and does not work offline. A dedicated hiking app provides: accurate topo maps with contour lines, trail-specific routing, offline capability for areas without cell service, community reviews and photos, and tools like track recording and elevation profiles.

Getting lost on a trail because you were relying on Google Maps is common and avoidable. Downloading the right app — and downloading its maps before you leave home — takes five minutes and has saved many hikes.

AllTrails Review

AllTrails is the most popular hiking app because it has the largest trail database — over 400,000 trails worldwide — and the most user-generated content: reviews, photos, and condition reports. For finding trails in a new area, checking difficulty and current conditions, and navigating well-marked trails, AllTrails is the best tool available.

Limitations: AllTrails is less useful for off-trail navigation and complex backcountry routing. The free version lacks offline maps. AllTrails+ ($35.99/year) adds offline maps and topo overlays but is still weaker than Gaia GPS or CalTopo for serious navigation. Best for: day hikers, weekend hikers, anyone exploring new regions with marked trails.

Gaia GPS Review

Gaia GPS is the go-to app for serious backcountry hikers and backpackers. It supports a wider range of map sources than any other app: USGS topo, satellite imagery, NatGeo trail maps, Thunderforest, snow coverage, and dozens more. You can layer maps (topo + satellite simultaneously), create custom routes, and record tracks with full offline capability.

The interface is more complex than AllTrails — there is a learning curve, particularly around map layers and route planning. Gaia Premium costs $39.99/year. Best for: backpackers, off-trail hikers, hunters, search and rescue volunteers, and anyone who needs serious offline navigation capability.

CalTopo Review

CalTopo started as a web-based topo mapping tool for search and rescue and has a dedicated following among technical backcountry users. Its standout feature is avalanche and terrain analysis — slope angle shading, aspect coloring, and relief shading make it the best tool for evaluating avalanche terrain before winter trips.

CalTopo's app is less polished than Gaia GPS but the desktop platform is exceptional for trip planning. Many serious backpackers plan routes on CalTopo, export them, and navigate with Gaia on their phone. Best for: winter mountaineers, backcountry skiers, anyone planning technical routes where terrain analysis matters.

Komoot Review

Komoot is strong on route planning and community-generated highlights — points of interest, photos, and local tips submitted by other hikers along a route. Its routing engine is good at suggesting appropriate trails based on your fitness level and preferences. Komoot is free for one region; additional regions or worldwide access requires a one-time purchase.

Komoot has excellent coverage in Germany, Austria, Switzerland, and the UK. US coverage is growing but still thinner than AllTrails for domestic trails. Best for: European hiking and international multi-sport users who also bike and run.

FarOut (Guthook) Review

FarOut (rebranded from Guthook) is purpose-built for long-distance thru-hikers. You purchase individual trail guides (AT, PCT, CDT, and dozens of others) that provide mile-by-mile waypoints, water sources, shelters, campsites, and user comments. If you are thru-hiking a named long trail, FarOut is the essential companion app — the depth and accuracy of its data for major routes is unmatched. It is not useful for general hiking outside supported trail systems.

Offline Maps: What to Know

Every serious hiking app offers offline map downloads, but the process and quality vary. Key points: download maps at home on Wi-Fi before the trip, not at the trailhead. Download a larger area than you think you need — if you get off-route, you want map coverage beyond your planned trail. Check that your downloaded area includes the full elevation profile and any alternate routes.

Offline GPS positioning does not require cell service — your phone's GPS chip works independently of the cellular network. What requires cell service is loading map tiles dynamically. With offline maps downloaded, the phone navigates accurately without any signal.

Phone Battery on Trail

GPS is one of the highest battery draws on a smartphone. On a full day of active GPS tracking, most phones will drain 30-50% of their battery. Mitigation: enable airplane mode (GPS still works, but cellular searching stops), reduce screen brightness, use the app only when actively checking position rather than leaving the screen on continuously. A 10,000 mAh power bank provides 2-3 full phone charges and is worth the weight on any multi-day trip.
