Support for both GPS and GLONASS is a meaningful advantage on a long trail that crosses dense forests, high ridges, and remote valleys. The receiver can maintain a position in more challenging environments than a GPS-only unit, while 8 GB of internal memory and a microSD card slot allow users to store additional map downloads.

The main limitation is the absence of the eTrex 32x's electronic compass and barometric altimeter. Hikers must move to establish a heading rather than rely on a stationary compass reading, and they will not receive the same altimeter-based elevation information. Nevertheless, the eTrex 22x is focused on dependable mapping and positioning, and its physical controls remain practical with gloves or wet hands.

This is a strong choice for hikers who want recognizable Garmin eTrex handling, preloaded mapping, and expandable storage without paying for extra sensors they may not regularly use. It is particularly suitable for section hikers who already understand how to follow an electronic route and want a simple tool for confirming position along the trail.

Confident Positioning Beyond GPS Alone

GLONASS support adds another satellite system to the receiver's positioning capabilities. That can be useful under tree cover and in steep country, where a clear view of the sky is uncommon along many Appalachian Trail segments.

Maps That Travel With You

Topo Active maps arrive preloaded, and the microSD card slot provides a convenient way to carry additional regional map data. This makes the eTrex 22x useful for long sections where detailed offline navigation matters more than live connectivity.

We may earn a commission when you buy through this link, at no additional cost to you.

The 2.2-inch sunlight-readable color display uses 240 by 320 pixels, and Topo Active maps with routable roads and trails are preloaded. GPS and GLONASS support improve positioning options in challenging terrain, while 8 GB of internal memory and a microSD card slot accommodate downloaded maps.

Its extra sensors are the defining advantages over the eTrex 22x. The electronic compass provides a heading without requiring movement, and the barometric altimeter adds elevation information that can be particularly valuable around rocky high points. The trade-off is a larger, more advanced unit whose small display still requires careful zooming when studying complex terrain.

The eTrex 32x suits experienced trail travelers who want dependable buttons, offline maps, and sensor-based orientation without moving to a touchscreen ecosystem. It is also a logical choice for hikers who frequently encounter fog, cloud cover, or terrain where knowing a reliable heading can make route confirmation faster.

Orientation Without Waiting for Motion

The three-axis compass is especially helpful during pauses. A hiker can check a bearing while standing still, which is useful in fog or when comparing several possible paths around a ridge or junction.

Elevation Context for High Country

The barometric altimeter gives the device an additional source of elevation information. It can help travelers understand the terrain ahead, identify changes in altitude, and navigate with more context than position and trail symbols alone.

Author Ben Montgomery interviewed surviving family members and hikers who met Gatewood, researched historic newspaper and magazine coverage, and received access to her diaries, trail journals, and correspondence. These sources create a detailed account grounded in both personal records and memories from people encountered along the route.

The subject also reveals the practical and political dimensions of maintaining the A.T. Gatewood's public criticism of difficult trail conditions was followed by bolstered maintenance, and the book examines how her advocacy may have helped save the trail from extinction. Its limitation is obvious: it cannot guide a hiker, display a map in the field, or replace a GPS.

This is a rewarding purchase for trail history enthusiasts, aspiring thru-hikers, and anyone who appreciates stories of perseverance in the outdoors. It can be especially valuable before a major hike, when the reality of sustained travel deserves greater context than a list of gear and mileage targets can provide.

A Trail Shaped by Its Advocates

The account demonstrates how individual hikers can influence public awareness and trail maintenance. That history gives modern travelers a broader appreciation of the volunteers and organizations responsible for keeping the A.T. usable.

Primary Sources Add Human Detail

Diaries, journals, correspondence, family interviews, and historic press coverage place the journey within its period. These details offer a more personal account than a purely retrospective hiking guide.

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

Choosing trail navigation equipment means balancing positioning reliability, map detail, physical controls, power requirements, and the amount of electronic complexity you genuinely need. The Appalachian Trail rewards preparation, so the most capable option is not automatically the most practical one.

Positioning and Satellite Support

Positioning quality is the central feature of any trail GPS because every downstream decision depends on knowing where you are. Basic GPS is only the starting point. The eTrex 22x and eTrex 32x add GLONASS, the eTrex SE supports five navigation satellite systems, and the GPSMAP 65s adds multi-band technology intended to improve accuracy in difficult terrain. These differences can matter under dense canopy, among steep rock formations, and in remote valleys where the sky is partially obscured.

Choose the level of satellite support that matches your route, experience, and tolerance for uncertainty. A more capable receiver may provide greater confidence, but it cannot remove the need to observe signs, terrain, junctions, and official trail information. A GPS should confirm a route, not replace attention to the trail itself.

Topographic Map Detail

The Appalachian Trail crosses varied terrain, so contour lines, named trails, waterways, roads, and land information can all be useful. The eTrex 22x, eTrex 32x, and eTrex 20x include preloaded basemaps, while the eTrex 22x and eTrex 32x specifically list Topo Active routable roads and trails. The generic 3.2-inch model includes USA topo maps, and the GPSMAP 65s includes routable Topo Active mapping plus a federal public land map.

Check which map package is actually included and whether additional regions can be stored offline. Expandable memory is valuable for multi-state trips, but the map must also be present on the device before coverage disappears. Download and test maps before the hike, not at a trailhead with a weak signal.

Compass and Altimeter Functions

A compass and barometric altimeter can make a handheld more useful when visibility is poor or terrain rises sharply. The eTrex 32x, generic 3.2-inch GPS, GPSMAP 65s, and Foretrex 401 include both an electronic compass and barometric altimeter. The eTrex SE includes a digital compass, while the eTrex 22x and eTrex 20x do not list these sensors in the supplied specifications.

A compass provides direction without requiring movement, and an altimeter adds elevation context beyond what the map itself communicates. Neither sensor replaces judgment. Calibrate the compass, understand altimeter effects, and treat both as supporting information rather than unquestionable answers.

Display Size and Readability

Screen size affects how much detail you can inspect without repeated zooming. The 2.2-inch eTrex screens are portable and familiar, the 2.6-inch GPSMAP 65s offers additional room, and the generic 3.2-inch handheld is the largest in this selection. The Foretrex 401 has a compact 1.42-inch LCD optimized for glanceable wrist information rather than detailed map study.

For long trail days, favor a sunlight-readable display with enough resolution to distinguish trail lines and small symbols. Larger screens are not automatically better because they consume more space and may be harder to operate with gloves. Balance detailed-map needs against pack weight and one-handed use.

Battery Life and Power Strategy

Battery strategy should reflect trip length, resupply frequency, and access to charging. The eTrex SE lists up to 168 hours in standard mode and 1,800 hours in expedition mode using replaceable AA batteries. The eTrex 22x and eTrex 32x list up to 25 hours in GPS mode, the generic model lists up to 36 hours with a rechargeable battery, and the Foretrex 401 lists up to 17 hours.

Field-replaceable batteries can be valuable on remote or extended journeys, while USB-C charging offers convenience for trips with regular access to power. Carry the appropriate batteries or a protected charging cable, and identify a backup navigation method before beginning. A long stated runtime is most useful when it matches the way you actually travel.

Controls and Outdoor Durability

The dedicated handhelds favor physical buttons, which are often easier to operate with cold fingers, gloves, rain, or dust. The GPSMAP 65s also emphasizes button operation. The eTrex SE has an IPX7 water-resistance rating, the generic 3.2-inch device is rated IP66, and the Foretrex 401 is described as waterproof. Water-resistance is not the same as permission to submerge or wash a device under every condition.

Choose a layout that lets you find essential functions without prolonged visual searching. Check button spacing, screen visibility, grip security, and carrying options. A protective case or pouch can add confidence during wet weather, but it must not block the screen, controls, antennas, or external connections.

Storage and Smartphone Connectivity

Offline storage is essential because cellular coverage is inconsistent along the trail. The eTrex 22x and eTrex 32x include 8 GB of internal memory and a microSD card slot, the eTrex 20x includes 3.7 GB plus a card slot, and the generic 3.2-inch model offers 32 GB of internal memory. The eTrex SE and GPSMAP 65s work with Garmin Explore for compatible smartphones, enabling route management, updates, weather information, and track review.

Decide whether you want a self-contained handheld or a connected workflow. Smartphone apps are convenient before and after the hike, but a phone should not be the only means of navigation because batteries drain, signals disappear, and weather can interfere. Use the handheld as the field authority and the phone as a planning companion.

Printed Trail Knowledge as a Backup

Paper and books provide context that an electronic unit cannot reproduce. The Appalachian Trail celebration book includes the official full-size trail map, while 101 Classic Hikes of the Northeast includes 101 detailed maps for planning sections and side trips. Printed references can help you understand the route before departure and provide a last-resort overview if electronics fail.

Print a small, weather-resistant route summary for essential segments and keep it separate from your main electronics. Know how to interpret its symbols and understand the limitations of an overview map. Digital detailed maps, official information, and attentive trail signs should still form the core of an active navigation plan.

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

Begin by learning the basic controls before your trip: zoom, pan, create a waypoint, mark a track, open the route, and read the position and battery screens. If the device connects to a smartphone, complete the relevant software and map updates while reliable service is available. Load every regional map needed for your itinerary and verify that the device can display it without a network connection.

On the trail, compare the GPS position with trail signs, topographic features, junctions, and the route you planned. Use the compass and elevation data as supporting clues, especially where tree cover, cliffs, or dense weather may affect your understanding of direction. Record a track when appropriate, conserve battery by adjusting settings, and keep the device secured but accessible.

Protect the unit with a case suitable for rain, mud, and impact while allowing access to controls. Keep spare batteries or the correct charging cable dry and accessible, clean the exterior after muddy hikes, and avoid charging a wet device. At home, back up important tracks and routes, document any configuration that works well, and inspect the device before each new segment.

Frequently Asked Questions

Do I need a dedicated GPS for the Appalachian Trail?

A dedicated GPS is not mandatory for every hiker, but it is highly useful for long or remote sections where reliable signs are limited. A smartphone with offline maps can work for many day hikes, although battery life, weather protection, and signal loss can be concerns. A dedicated handheld offers physical controls, longer battery options, and a more predictable field experience.

What is the most important feature in a hiking GPS?

Reliable positioning and usable offline maps are the most important foundation. Satellite support, a readable screen, and long battery life make those fundamentals more dependable. A compass and altimeter are valuable additions, but none of these features replaces careful route preparation or attention to official trail information.

Is a multi-band GPS necessary for Appalachian Trail hiking?

Multi-band technology can improve accuracy in challenging terrain, especially beneath dense trees or among steep rock formations. The GPSMAP 65s is the dedicated unit in this guide that lists it. Hikers on well-marked, familiar sections may not need that capability, while travelers on remote, complex routes may value the added confidence.

Should I rely on my smartphone instead of a handheld GPS?

A smartphone is convenient for planning and downloading maps, but a dedicated handheld is generally more robust for sustained trail use. Phones can suffer from cold-related battery loss, moisture exposure, accidental drops, and limited signal availability. Carrying both can be useful if the handheld remains the primary field navigator and the phone supplies planning extras.

How do I prepare a GPS for a long Appalachian Trail hike?

Download all necessary maps, update the device and related app, save a primary route, and test the controls away from the trail. Learn how to record tracks, create waypoints, read elevation data, and switch screens without looking for long. Also prepare a paper backup and know how to continue if the battery or device fails.

Are AA batteries better than a rechargeable GPS battery?

There is no universal winner. Replaceable AA batteries are convenient for remote travel because spare cells can be carried, while a rechargeable system reduces repeated battery purchases and works well when charging is accessible. The eTrex SE emphasizes long standard and expedition runtimes with field-replaceable batteries, while the generic 3.2-inch unit uses USB-C charging.

Do I need a compass and barometric altimeter?

They are not mandatory, but both can improve orientation and terrain awareness. A compass gives a heading without requiring movement, while an altimeter provides elevation context that can help on steep ridges. Hikers should still learn to use them correctly, carry a separate compass if they depend on one, and treat electronic readings as supporting information.

Can trail books replace an electronic GPS?

A trail book can support planning and provide historical context, but it cannot show a live position or adapt to a missed turn. The Appalachian Trail celebration book and 101 Classic Hikes of the Northeast are valuable references. They work best alongside a dedicated GPS, official updates, paper route notes, and attentive observation of trail signs.

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

The Garmin GPSMAP 65s is the strongest all-around choice for hikers who value multi-band positioning, a larger color display, topographic mapping, and integrated navigation sensors. The Garmin eTrex SE is the best budget-oriented option for travelers who want broad GNSS support, long battery runtimes, and optional Garmin Explore connectivity, while the Garmin eTrex 32x is the premium rugged choice for those who prefer physical controls, an electronic compass, and an altimeter.

Prioritize the conditions you will actually encounter. Choose detailed offline maps, dependable positioning, readable controls, and a power strategy that matches your resupply rhythm. Electronic features matter, but offline preparation, physical map backup, battery discipline, and consistent attention to signs are equally important for safe navigation.

Before buying, verify the current version, included maps, accessories, compatibility, and availability directly on the product listing. Ratings and customer feedback can change over time, and prices fluctuate, so compare the complete feature set rather than selecting solely from a temporary cost or headline specification.
