Author Ben Montgomery interviewed surviving family members and hikers who encountered Gatewood, examined newspaper and magazine articles, and received access to her diaries, trail journals, and correspondence. The result is a detailed account of her 1955 walk, her later repeat hikes, and the public attention that contributed to increased trail maintenance and preservation.

As a navigation resource, it has no practical function: it does not provide a live position, current trail conditions, route calculations, or usable topographic mapping. It should not be chosen to replace a handheld GPS or current official resources. Its value is historical and motivational, helping readers understand why trail maintenance and public advocacy have always been inseparable from the hiking experience.

The book is an excellent choice for prospective thru-hikers, history readers, and anyone who wants to understand the Appalachian Trail as more than a recreational route. It can add context and inspiration before a long hike, but hikers still need dedicated navigation equipment such as the eTrex 22x, GPSMAP 65s, or eTrex SE.

Primary Sources Bring History to Life

Diary entries, personal journals, correspondence, and period media reports allow readers to encounter Gatewood's experience through contemporary sources. That archival depth distinguishes the book from a general hiking history or a short collection of trail anecdotes.

The Role of Public Advocacy

Gatewood's criticism of difficult trail sections and her resulting visibility helped bring broader attention to maintenance needs. The story illustrates how encounters with the A.T. can shape its history, making it particularly meaningful for hikers pursuing long-distance or volunteer goals.

Buying Guide – How to Choose the Best GPS for Hiking the Appalachian Trail

Choosing a trail GPS requires balancing positioning accuracy, map detail, physical controls, battery strategy, and durability. The Appalachian Trail crosses varied forests, ridges, and weather, so the most suitable device is one that remains understandable and dependable when conditions are less than ideal.

Satellite Reception and Accuracy

A trail GPS receives signals from navigation satellites, and the number of supported systems can affect acquisition speed and stability. The eTrex SE supports GPS, GLONASS, Galileo, BeiDou, and QZSS, while the GPSMAP 65s adds multi-band technology for challenging locations. These advanced systems can be worthwhile for long-distance hikers who regularly travel under dense canopy or through steep terrain.

Choose the broadest satellite support and positioning features your experience requires. A basic GPS-only unit can work for many hikers, but extra system support is valuable when dependable position updates matter more than minimizing equipment cost.

Map Detail and Coverage

A clear position is only useful if the device can show the surrounding trail network, roads, waterways, and terrain. The eTrex 22x and 32x include preloaded TopoActive mapping with routable trails, while the GPSMAP 65s adds federal public-land mapping. Other models may require compatible downloads, storage cards, or subscriptions for the level of detail a hiker wants.

Prioritize a trail-focused map set that covers the states or regions you expect to visit, and confirm whether additional maps can be installed. For an end-to-end A.T. trip, a downloadable regional approach is usually more practical than depending on one fixed basemap.

Display Readability and Controls

The screen should remain readable in direct sunlight and legible while the device is moving. A larger 3.2-inch display offers more visible map detail, while the 2.2-inch eTrex models remain more compact. Physical buttons are also useful in cold weather, rain, or while wearing gloves, and they reduce the need to unlock a touchscreen after every stop.

Choose a screen size that balances visibility and pack space, and favor tactile controls for serious trail use. Avoid assuming a larger display is automatically better; a clear map at a sensible scale is more useful than a large screen showing too little surrounding context.

Compass and Altimeter Sensors

A three-axis compass provides a direction when stationary, while a barometric altimeter measures elevation. These sensors add useful redundancy when a trail is obscured, a sign is missing, or a hiker needs to understand a climb. The eTrex 32x, GPSMAP 65s, Foretrex 401, and the 3.2-inch handheld include both features.

Include a compass and altimeter if you hike off marked routes or value independent orientation references. For straightforward trail following, they are helpful but not necessarily essential, so a simpler model can remain a reasonable choice.

Battery Life and Power Strategy

The A.T. places hikers far from outlets on many occasions, making endurance a major consideration. Battery claims vary sharply by mode: the eTrex 22x and 32x offer up to 25 hours in GPS mode, the Foretrex 401 lists up to 17 hours, and the eTrex SE reaches up to 1,800 hours in expedition mode. Rechargeable devices can be convenient, but spare batteries may be difficult to obtain during a long section.

Match the power system to the length of your trip. Day hikers may manage a rechargeable unit easily, while thru-hikers should consider replaceable batteries, carry adequate backups, and understand how different modes affect battery consumption.

Durability and Water Resistance

Trail electronics must tolerate rain, humidity, mud, dust, and repeated impacts. The eTrex SE has an IPX7 rating, while the 3.2-inch handheld uses IP66. Water-resistance ratings do not mean every unit can be submerged under identical conditions, and a protective case can provide additional security during demanding hikes.

Choose a rugged model with physical controls and an appropriate water-resistance rating for expected conditions. Keep the device protected during prolonged downpours and avoid treating a rating as permission to submerge or rinse it under conditions outside the manufacturer's guidance.

Storage and Software Flexibility

Storage determines how many detailed map regions, routes, waypoints, and tracks a device can hold. The eTrex 22x and 32x provide 8 GB internally and a microSD slot, the GPSMAP 65s includes routable TopoActive maps, and the 3.2-inch handheld offers 32 GB. Some older eTrex models support additional map formats but may require more manual setup.

Prioritize enough storage for your planned route, not merely the largest number available. Verify map compatibility, download procedures, and whether the device can be used independently when a smartphone is out of reception.

Paper and Digital Redundancy

Electronic navigation can fail through a drained battery, damaged controls, firmware trouble, or an inaccurate position. The official Appalachian Trail book includes a removable full-size National Park Service map, while 101 Classic Hikes of the Northeast offers detailed regional maps. Neither replaces live navigation, but both can strengthen trip preparation and provide offline context.

Carry a paper map, a compass, and spare power whenever the trail enters remote areas. Redundancy is not merely for equipment failure; printed maps can help hikers understand the route's overall shape and recognize landmarks that a small device cannot show clearly.

How to Use and Care for Your GPS for Hiking the Appalachian Trail

Before leaving home, power the unit fully, install fresh or charged batteries, confirm that the correct date and time are displayed, and review the maps for the areas you will cross. Download the needed regional maps before losing reception, save essential trail junctions and water points as waypoints, and attach the unit to a strap or belt rather than carrying it loose.

While hiking, open the track and navigation pages periodically instead of checking the position constantly. Keep the device in a protected pocket or pouch when it is not in use, and allow it to acquire a clear satellite view when entering a new area. Learn the compass, breadcrumb trail, waypoint, and elevation functions before encountering a difficult junction or steep ridge.

After the hike, remove the batteries from any device that will be stored for an extended period, clean dirt from the buttons and ports, and dry the unit before storage. Keep software and map information current, download updated official trail information, and inspect the housing, lanyard, and case for damage before the next trip.

Frequently Asked Questions

Which Garmin GPS is the best choice for an Appalachian Trail thru-hike?

The GPSMAP 65s is the strongest dedicated choice for hikers who prioritize multi-band accuracy, a larger color display, compass and altimeter functions, and downloadable mapping. The eTrex SE is an attractive alternative for maximum battery endurance and broad GNSS support. A thru-hiker should compare map availability, power strategy, and personal comfort with physical controls before choosing.

Do I still need a paper map if I have a handheld GPS?

Yes, carrying a paper map is a sensible safety practice even when you use a dedicated electronic navigator. Batteries can fail, controls can be damaged, and a GPS may not include the latest closure or access information. A map that shows the broader route can also help you recognize landmarks and understand how trail segments fit together.

Is a smartphone enough for hiking the Appalachian Trail?

A smartphone can be highly effective when paired with downloaded offline maps, an appropriate power bank, and a protective case. Its disadvantages include screen visibility, weather vulnerability, battery drain, and dependence on a touch interface. Many hikers carry a phone for flexible mapping while also bringing a dedicated handheld for more dependable outdoor operation.

How much storage do I need for Appalachian Trail maps?

Storage needs depend on the map detail, number of states, and whether you save tracks, routes, and waypoints. A multi-state trip can require substantially more regional mapping than a single section. Choose a model with adequate internal storage and expansion, and confirm that the relevant trail or topographic maps can actually be downloaded before departure.

What battery life is realistic for a long-distance trail GPS?

Actual runtime depends on satellite reception, screen use, temperature, and the selected power mode. Published maximum figures are best treated as comparative guidance rather than guaranteed results. Thru-hikers should carry spare batteries or a compact charging solution, reduce unnecessary screen checks, and select a lower-power mode when precise updates are not needed.

Do I need both a compass and an altimeter in my GPS?

They provide useful redundancy but are not equally important for every trip. A compass helps establish direction when stationary or when the trail is unclear, while an altimeter adds elevation context and supports profile tracking. Hikers exploring unmaintained routes, navigating ridges, or seeking greater confidence away from signed trails receive more benefit from both.

Can these GPS devices navigate without cell service?

Dedicated handheld GPS units determine position using navigation satellites and do not require cellular reception for basic positioning. Their maps and stored routes can also work offline, provided the needed data has already been downloaded. Phone-linked features such as weather updates or smart notifications may still require a compatible connection.

Which pick is easiest to operate in rain or while wearing gloves?

The eTrex 22x, eTrex 32x, GPSMAP 65s, and the 3.2-inch handheld all use physical buttons, making them practical in wet conditions and while wearing gloves. Interface familiarity matters as much as button count, so prospective buyers should compare menus and operating procedures before the trip rather than learning a complex device on the trail.

Final Thoughts on Choosing the Best GPS for Hiking the Appalachian Trail

The Garmin GPSMAP 65s is the leading dedicated option because it combines multi-band positioning, a 2.6-inch color display, routable TopoActive mapping, and a compass and altimeter. The eTrex 22x offers a simpler and more economical route with preloaded trail mapping, while the eTrex SE stands out for broad GNSS support and exceptional expedition-mode endurance.

Choose according to the demands of your trip rather than a feature checklist alone. Day hikers may need little more than reliable mapping and a readable screen, section hikers may value expandable storage and replaceable batteries, and thru-hikers should prioritize position stability, power planning, and offline redundancy. The three books in the list are valuable companions for history, route context, and regional trip ideas, but none replaces a live navigator.

Before purchasing, verify that the device supports the map coverage and satellite systems you need, compare its controls with your hiking experience, and check its physical size against your pack. Product features, software compatibility, and prices can change, so confirm the latest specifications and current cost before making a final decision.
