GPS vs. Paper Maps: Which Should You Carry?

The answer is both. But understanding when each tool excels — and fails — helps you navigate confidently in any situation.

GPS Devices

Dedicated GPS (Garmin, COROS)

Strengths:

• Long battery life (20–40 hours in GPS mode)
• Purpose-built for outdoor use (waterproof, durable, sunlight-readable)
• Works without cell service
• Breadcrumb trails show exactly where you have been

Weaknesses:

• Small screens limit map detail
• Expensive ($200–600)
• Can malfunction in extreme cold
• Learning curve for advanced features

Best picks: Garmin GPSMAP 67, Garmin inReach Mini 2 (includes satellite communicator)

Smartphone Apps

Strengths:

• Large, high-resolution screen
• Excellent offline map apps (Gaia GPS, AllTrails, FarOut/Guthook)
• Camera, emergency communication, and navigation in one device
• Most hikers already own one

Weaknesses:

• Battery drains fast in GPS mode (4–8 hours)
• Fragile (screen cracks, water damage)
• Cold weather kills battery life
• Temptation to use for non-navigation purposes (drains battery)

Extend phone battery life:

• Airplane mode when not actively navigating
• Screen brightness at minimum
• Carry a battery bank (10,000 mAh = 2–3 full charges)
• Use a power-saving GPS mode if available

Paper Maps

Strengths:

• Never runs out of battery
• Big-picture overview of terrain that no screen matches
• No learning curve for basic use
• Lightweight (1–2 oz per map)
• Works in any weather with waterproof paper

Weaknesses:

• Does not show your exact position
• Requires compass skill for precision navigation
• Bulky to carry multiple maps for long routes
• Can be damaged by wind and rain without protection

3. Small battery bank

Multi-Day Backpacking

Pro Tips

• Always download maps before leaving service. "I'll do it at the trailhead" is a recipe for disaster.
• Mark key waypoints: trailhead, junctions, water sources, camp, and emergency exit points
• Practice with your tools at home before relying on them in the field
• Triangulate: When uncertain of position, cross-reference GPS position with visible terrain features on your paper map
