The Mardi Himal Trek follows a clear, well-trodden trail, and every foreign trekker now walks with a licensed guide, so you do not need advanced navigation skills to reach Base Camp. Even so, an offline map on your phone is one of the most useful tools you can carry. It shows where you are, how far you have come and how much height remains, which is reassuring on long forest days. It helps you understand the landscape around you, from the Modi Khola valley to the peaks on the skyline. And in the rare event that you become separated from your group in fog, it can help you find the trail.
This guide covers the best offline map apps, how to set them up before you leave, paper maps, GPS watches and satellite messengers, and how to keep your devices charged in the cold. For the route itself, see the map and route guide, and for following the trail on the ground, trail markings and navigation.

OpenStreetMap-Based Apps
For most trekkers, the best choice is an app based on OpenStreetMap, the collaborative, open map of the world. The Mardi Himal trail, its main junctions and most of its lodges are mapped in OpenStreetMap, from Kande, Dhampus and Australian Camp through Pitam Deurali, Forest Camp, Rest Camp and Low Camp to Badal Danda, High Camp and Base Camp, along with the descent to Siding. Popular apps that use this data include Maps.me and OsmAnd, both available for Android and iOS.
These apps let you download the map of Nepal, or a smaller region, before your trip, then use it entirely offline. Your phone's GPS works without mobile signal, so you can see your position on the trail at any time. Many also show contour lines or elevation, let you search for lodges and viewpoints, and allow you to save your own points. Accuracy is generally good, though small details such as exact lodge locations or recent trail diversions may be out of date, so treat the map as a guide rather than gospel.
Hiking Apps with Topographic Maps
Dedicated hiking and outdoor apps offer detailed topographic maps with contours, shaded relief and elevation profiles, and they let you import or record GPX tracks. They are useful if you want to plan each day's climbing, compare your progress against an elevation profile, or record your route as a keepsake. Many of these apps require a paid subscription for offline maps. If you already use one at home, check that it offers offline coverage of Nepal and download the area around Pokhara and the Annapurna foothills before you leave.
Google Maps
Google Maps is excellent for Pokhara and Kathmandu, where it shows hotels, restaurants, roads and bus stations, and you can download offline areas for both cities. On the trail, however, its coverage of walking paths in the Himalaya is less reliable than OpenStreetMap-based apps. Some sections of the Mardi Himal trail may be missing or shown inaccurately. We suggest using Google Maps for cities and roads, and an OpenStreetMap-based app on the trail.
Setting Up Before You Go
- Download maps at home or in your hotel, over a fast Wi-Fi connection. Map files can be large, and lodge Wi-Fi is slow.
- Download both Nepal and the local region in at least one app, plus a backup app.
- Save key points: your hotel in Pokhara, Kande or Phedi, each overnight lodge, High Camp, Base Camp and Siding.
- Test the app offline in airplane mode to make sure the maps and GPS work.
- Import a GPX track of the route if you have one, and check it matches the mapped trail.
- Enable battery-saving settings such as offline mode and a dim screen.
See the pre-trek checklist.
Paper Maps
A paper trekking map of the Annapurna region is a good backup, and many trekkers find it more helpful than a phone for understanding the big picture. It shows the whole landscape at once, with valleys, ridges, rivers, villages and peaks, so you can see how the Mardi Himal ridge relates to the Modi Khola, the Annapurna Sanctuary and Pokhara. Paper maps are widely available in bookshops and trekking shops in Pokhara's Lakeside and Kathmandu's Thamel. They are less detailed than phone apps and do not show your position, but they never run out of battery. See reading a trekking map.
GPS Watches
A GPS watch with an altimeter is a nice extra rather than a necessity. It tracks distance, altitude, pace and heart rate, and its battery usually lasts much longer than a phone in GPS mode. It is particularly useful for monitoring your ascent rate and for recording your route. Some watches can display a breadcrumb trail or a basic map, which can help in fog. If you already own one, bring it; if not, a phone app is enough for this trek.
Satellite Messengers
Satellite messengers are small devices that send messages and SOS alerts via satellite, without mobile signal. They let you share your location with family, send short check-in messages, and trigger an emergency alert if something goes seriously wrong. On the Mardi Himal Trek, where your guide can usually reach help by phone from a lodge, they are not essential, but some trekkers value the peace of mind, especially for family at home. Some newer smartphones also offer satellite emergency messaging in certain regions; check whether it works in Nepal before relying on it. See emergency communication on Mardi Himal.
Mobile Signal on the Trail
Mobile coverage on the Mardi Himal Trek is patchy. It is generally available near the trailheads at Kande and Phedi, in Dhampus, at Australian Camp and in Siding. In the forest between Pitam Deurali and Low Camp, it becomes intermittent, and on the upper ridge it varies with location and network. Many lodges offer Wi-Fi, sometimes for a fee, but connections can be slow or unavailable in bad weather. Buying a local SIM card in Pokhara or Kathmandu gives you the best chance of signal. Do not rely on mobile data for maps; download everything before you go. See getting a SIM card and Wi-Fi, signal and charging.
Keeping Devices Charged
GPS use drains phone batteries quickly, and cold temperatures at High Camp make batteries lose charge even faster. Lodges usually offer charging, sometimes for a small fee, but power can be limited, especially on the upper ridge, where solar power is common. To keep your devices running:
- Carry a power bank of at least 10,000 mAh, ideally 20,000 mAh.
- Keep your phone and power bank warm, in an inside pocket by day and in your sleeping bag at night.
- Use airplane mode when you do not need signal; GPS still works.
- Close apps you are not using and lower screen brightness.
- Charge whenever you have the chance at lower lodges.
- Consider a small solar panel if you are a heavy user.
See power banks and charging gear.
Using Maps on the Trail
On the trail, use your map app to check progress, not to replace your guide. Glance at it at rest stops to see how far you have come and how much climbing remains. Compare the altitude shown with what you feel; it helps you understand how your body is responding to height. In fog on the ridge, check your position if you are unsure of the trail, but always stay with your group and follow your guide's instructions. Maps can be wrong, and your guide's local knowledge is more reliable. See trekking in fog.
Recording Your Trek
Many trekkers enjoy recording their route with a GPS app or watch and sharing it afterward. A track of your trek, with elevation profile and photos pinned to locations, makes a great souvenir, and it helps future trekkers if you share it responsibly. Keep in mind that GPS altitudes can be off by tens of meters, and different devices report different figures, which is one reason published altitudes for places like High Camp and Base Camp vary. See distance, duration and elevation explained.
Why You Still Need a Guide
Since 2023, foreign trekkers in Nepal's national parks and conservation areas, including the Annapurna Conservation Area, have been required to trek with a licensed guide. On Mardi Himal, this rule makes sense. The trail is clear in good weather, but fog on the ridge, snow in winter, or an injury can change things quickly. A guide knows the terrain, the weather patterns, the lodges and the people, and can make decisions and get help in ways no app can. Offline maps are a useful complement to a guide, not a substitute. See is a guide mandatory for Mardi Himal? and hiring a guide.
Key Points to Save in Your App
Before you set off, it is worth saving the main points of the route as favorites in your map app, so you can see at a glance how far you are from the next stop. A typical list might look like this:
| Point | Approximate altitude | Why save it |
|---|---|---|
| Kande or Phedi | About 1,770 m / 1,130 m | Trailhead and road access |
| Australian Camp | About 2,060 m | Viewpoint and lodges |
| Pothana | About 1,990 m | Checkpoint and trail junction |
| Pitam Deurali | About 2,100 m | Junction with the Landruk trail |
| Forest Camp | About 2,600 m | Overnight lodges |
| Low Camp | About 2,970 m | Overnight lodges; junction for Siding |
| High Camp | 3,580 m | Base for the summit hike |
| Upper View Point | About 4,200 m | Sunrise viewpoint |
| Base Camp | About 4,500 m | Highest point of the trek |
| Siding | Around 1,750 m | End point and jeep pickup |
Altitudes vary between maps and devices, so do not worry if your app shows slightly different figures. What matters is the relative height between points, which helps you plan your energy for the day. See the day-by-day itinerary.
Understanding Elevation on Your Map
One of the most useful features of a good map app is the elevation profile, which shows how the trail climbs and descends along the way. On the Mardi Himal Trek, this reveals the shape of each day: a steep climb from Kande to Australian Camp, a long, steady forest climb from Pitam Deurali to Forest Camp and Low Camp, the stepped ascent of the ridge to High Camp, and the big climb of summit day. Knowing that a steep section is coming, or that the day's climbing is nearly over, makes pacing easier and keeps morale up. It also helps you appreciate the scale of the final descent to Siding. See daily walking hours on Mardi Himal.
