How to Use a GPS Watch for Hiking
A GPS watch is one of the most useful hiking tools available — it tracks your location, navigates routes, monitors weather, and does it all from your wrist. Here is how to use it effectively.
Choosing a GPS Watch for Hiking
Key Features
- GPS accuracy: Multi-band (L1+L5) GNSS provides the best accuracy in canyons and dense forest
- Battery life: 24+ hours in GPS mode; 40+ hours in power-saving mode
- Navigation: Breadcrumb trails, waypoints, and route following
- Barometric altimeter: More accurate elevation than GPS alone, plus storm alerts
- Mapping: Topographic maps on screen (premium models)
- Durability: Sapphire crystal, water resistance to 100m

Pre-Hike Setup
Download Maps
- Download offline maps for your hiking area before leaving cell service
- Garmin: Use Garmin Connect or Garmin Explore to download map tiles
- COROS: Use the COROS app to download
- Resolution: 1:24,000 topo maps for best detail
Create a Route
- Plan your route in the companion app (Garmin Connect, COROS app, Suunto app) or on a website (Garmin Explore, AllTrails, CalTopo)
- Sync the route to your watch
- On the trail, follow the breadcrumb line on your watch's map screen
- The watch will alert you if you deviate from the route
Set Waypoints
Mark important locations:
- Trailhead / car
- Trail junctions
- Water sources
- Camp location
- Emergency exit points
On-Trail Navigation
Following a Route
- The watch shows a line (your planned route) and your position
- An arrow or bearing indicator points toward the next waypoint
- Distance remaining and estimated time are displayed
Breadcrumb Tracking
- Even without a pre-loaded route, the watch records your path
- "Back to start" or "TracBack" follows your breadcrumbs in reverse
- Invaluable when you need to retrace your steps in low visibility
Compass
- The watch's electronic compass works like a traditional compass
- Calibrate before each trip (most watches prompt automatically)
- Useful for bearing navigation between waypoints
Battery Management
Extend Battery Life
- Use power-saving GPS mode (reduces accuracy slightly but doubles battery)
- Turn off Bluetooth and phone notifications
- Reduce screen brightness
- Enable auto-sleep on screen
- For multi-day trips: charge with a small battery bank using the included cable
Battery Budget
Before a trip, calculate:
- Hours of GPS tracking needed
- Regular watch use time
- Total vs. battery capacity
- Carry a cable and small power bank if the math is tight
Weather Features
Storm Alert
- Watches with barometric altimeters detect rapid pressure drops
- A sudden pressure drop (>2 hPa in 3 hours) indicates an approaching storm
- Enable storm alerts — they can give 1–3 hours of warning
Sunrise/Sunset
- Know exactly when daylight ends — crucial for trip timing
- Most watches display this on the main screen
Post-Hike
- Sync your activity to review distance, elevation, pace, and route
- Share with hiking partners or save for future reference
- Use the elevation profile to understand the trail for next time
- Track cumulative stats (annual mileage, total elevation gain)
