Best Cheap Hiking GPS Devices in 2026

Your phone can do a lot in the mountains. Navigation isn't one of the things it does particularly well. A cheap hiking GPS isn't glamorous kit, but a dedicated device is more reliable than a smartphone in exactly the situations that matter: cold weather, all-day battery drain, rain, and the moments when you most need accurate position data.

Do You Actually Need a Dedicated GPS?

Honestly, it depends on where you hike. For well-marked day hikes on popular trails, a phone with an offline map app does the job. For multi-day routes in remote terrain, the case for a dedicated device gets stronger quickly.

Where phones fall short:

Battery life is the main problem. A smartphone running GPS continuously drains in 6-10 hours depending on the model and temperature. In cold conditions that figure drops further. If you're hiking 8-hour days for a week, you'll spend a lot of mental energy managing battery. A power bank adds weight and another thing to charge.

Durability is the second issue. Phones aren't built for impact and moisture the way dedicated GPS units are. Most of the devices on this list are rated to IPX7 or higher, meaning they can be submerged to a metre for 30 minutes without damage.

Finally, smartphone GPS accuracy can be patchy in deep valleys or under thick tree cover. Dedicated GPS units use more sophisticated antenna arrays and typically lock on to satellite signals faster.

When a phone app is sufficient: Day hikes, popular routes with good signage, and trips where you have a reliable charging setup (car camping, hut to hut with electricity). Apps like OS Maps, Gaia GPS, and Komoot are excellent tools, and in those contexts there's no need to carry an extra device.

What to Look for in a Cheap Hiking GPS

Battery type: AA batteries are a significant advantage. You can buy them anywhere in the world and carry spares without worrying about charging infrastructure. Some devices use proprietary lithium packs, which last longer per charge but require a cable to recharge.

Waterproofing: Look for IPX7 as a minimum. Most Garmin devices exceed this.

Map compatibility: Some budget units come with basic maps and let you load additional maps from Garmin's store (which costs extra). Others come with full topo maps included. Read the spec carefully.

Barometric altimeter vs GPS-only altitude: GPS altitude is accurate to roughly 10-15m vertically. A barometric altimeter, calibrated from a known point, gives you much better precision and also acts as a weather warning (dropping pressure usually means incoming weather). It's worth paying for on multi-day mountain trips.

Screen size and readability: Small screens are hard to read with gloves on. Touchscreens are convenient but can be unresponsive when wet.

The Best Budget Hiking GPS Devices

Garmin eTrex 22x (Around £120)

The eTrex 22x is the entry point for serious dedicated GPS. It's compact, runs on two AA batteries for up to 25 hours, and has a 2.2-inch colour screen that's readable in direct sunlight. The unit comes preloaded with a basic worldwide basemap, and you can load Garmin's TopoActive maps separately.

What you don't get: a barometric altimeter, a 3-axis compass, or topo maps out of the box. For straightforward navigation on marked trails, none of those absences matter much. For serious off-trail navigation or summit attempts where knowing your exact altitude matters, they do.

The eTrex 22x is the right choice if you want a reliable backup navigation device at a low price point, or if you're new to dedicated GPS and not yet sure how much you'll use it.

Best for: Budget-conscious hikers, trail walkers, beginners to dedicated GPS navigation.

Garmin eTrex 32x (Around £200)

The 32x adds the two features the 22x lacks: a barometric altimeter and a 3-axis tilt-compensated compass. Both matter in the mountains.

A 3-axis compass works correctly even when the unit is tilted, unlike a basic electronic compass that requires you to hold the device flat. On rocky terrain where you're often holding the GPS at an angle, this makes a real difference. The barometric altimeter reads altitude accurately and warns you about changing weather conditions by tracking pressure trends.

Battery life matches the 22x at 25 hours on two AAs. Screen size is identical. The unit is about 15% heavier than the 22x, though still well under 200g with batteries.

For anyone doing multi-day mountain hiking, the 32x is worth the extra £80 over the 22x. The altimeter and compass alone justify the jump.

Best for: Multi-day mountain hikers, off-trail navigation, anyone wanting accurate altitude data.

Garmin Montana 700 (Around $350)

The Montana 700 is a clear step up in price and size, so it sits above the "cheap" picks rather than alongside them. The draw is a large 5-inch touchscreen that works with gloves, paired with full topo maps included out of the box. If you find small handheld screens fiddly, this is the comfortable upgrade.

You also get ANT+ connectivity, which lets the unit pair with compatible sensors (heart rate monitors, cycling cadence sensors, and so on), a dual-orientation screen, and a rugged build aimed at vehicle and handlebar mounting too. Battery life runs to around 18 hours in GPS mode on the internal lithium pack, and you can fit AA batteries as a backup, which is reassuring on long trips.

For serious multi-day hiking where you want the full navigation picture on a screen you can actually read at a glance, the Montana 700 is the sensible ceiling on this list. The big touchscreen is genuinely more comfortable to use than the button-based eTrex when you're tired and just want to check your position quickly. Just be clear-eyed about the cost: at around $350 this is a premium choice, not a budget one.

Best for: Hikers who want full topo maps and a large touchscreen, and who are happy to pay a premium for screen size and usability.

Garmin GPSMAP H1i Plus (Around $900)

The GPSMAP H1i Plus sits at the very top of this list and well above any "cheap" threshold. This is the splurge, the pick for when budget genuinely isn't the deciding factor. It earns a mention because it combines two separate pieces of kit: a full-featured GPS navigator and a Garmin inReach satellite messenger.

Garmin GPSMAP H1i Plus

The inReach component lets you send and receive messages, trigger an SOS via the satellite network, and share your location with contacts, even in places with no phone signal. For remote hiking or long routes like multi-week expeditions, that safety net is worth serious consideration. Buying a standalone GPS and a separate satellite messenger adds up too, so combining both in one device is part of the appeal. Still, at around $900 this is a premium purchase, so only step up to it if the all-in-one design and top-end build are worth the outlay to you.

It's worth reading our guide to hiking satellite phones to understand the difference between a personal locator beacon, a satellite messenger like inReach, and a full satellite phone. The GPSMAP H1i Plus is in messenger territory: you can have a conversation, not just send a distress signal.

Battery life is excellent in GPS mode. It uses AA batteries, which puts it back on the right side of that debate for long trips far from a charger.

Best for: Remote mountain hikers and solo long-distance trekkers with a generous budget who want GPS and satellite communication in one device.

Phone Apps: When They're Enough

If you've decided a dedicated GPS isn't for you right now, these are the apps worth using.

OS Maps (UK and Ireland only): The gold standard for UK hiking. Full 1:25,000 Ordnance Survey maps, downloadable offline. Around £30/year. If you hike in Britain, you want this.

Gaia GPS: The most popular option for international hiking. Excellent map library, good offline support, clean interface. Around $40/year for premium. Works well on multi-day routes.

Komoot: Stronger on route planning than live navigation, but the offline maps are solid and the route recommendations for hiking are genuinely useful. Free for a single region, or around €30 for worldwide.

AllTrails Pro: Best for finding new routes rather than navigating remote terrain. Crowdsourced trail data, condition reports, and photos. Less suitable as your primary navigation tool in remote areas.

The honest limitation of all phone apps: they depend on your phone battery. For day hikes with a power bank or car charging at the end of the day, they work well. For week-long mountain routes, a dedicated device is a much safer bet.

Frequently Asked Questions

For day hiking on well-marked trails, probably not. For multi-day remote routes, yes. The battery life difference is the main factor. A Garmin eTrex will run for 25 hours on two AA batteries. An iPhone running GPS continuously typically lasts 6-8 hours. Over a week-long trip that difference is significant.

Yes, except for the GPSMAP H1i Plus's satellite messaging feature, which requires an active Garmin inReach subscription to function. The GPS navigation features on all devices work without any subscription. Additional map purchases (for eTrex models) are one-off costs, not recurring fees.

The 32x adds a barometric altimeter and a 3-axis tilt-compensated compass. Those are meaningful upgrades for mountain hiking where accurate altitude and reliable compass direction matter. Everything else (battery life, screen size, form factor) is essentially identical.

The Montana 700 has cycling and skiing activity profiles built in. The eTrex models are primarily hiking focused but will track position for any outdoor activity. The GPSMAP H1i Plus supports multiple activity types. All devices show your position regardless of activity; it's the additional metrics that differ.

Most modern Garmin devices support multiple satellite systems (GPS, GLONASS, Galileo) and are accurate to 3-5m under good sky conditions. In deep canyons or under dense tree cover, accuracy degrades. Barometric altimeters give better vertical accuracy than GPS altitude alone.

For marked trails you know well, a basemap showing roads, major terrain features, and your position is enough. For off-trail navigation, identifying the right ridge line, or planning in unfamiliar mountain terrain, topo maps are worth having. The Montana 700 and GPSMAP H1i Plus include them; the eTrex models require a separate map purchase.

A good GPS device won't make navigation decisions for you, but it removes the uncertainty about where you actually are. For the kinds of routes where that uncertainty could become a real problem, the £120-200 entry cost for a Garmin eTrex is a reasonable investment. If you're heading into genuinely remote terrain solo and your budget can stretch, consider stepping up to the GPSMAP H1i Plus and getting the satellite communication capability at the same time. Just know it's a premium splurge, not a cheap pick.
