I was wandering through a Portuguese village at 11 PM, phone showing “No Service,” trying to find my rental apartment. Google Maps was useless. The address existed, but the map was a grey void.

That was four years and 12 countries ago. I’ve since learned to download offline maps before every trip. The feature exists. It works. Almost nobody uses it until they need it.

Value for Cost	★★★★★

Best for: Any traveler going somewhere with unreliable data Skip if: You have unlimited international roaming (you probably don’t) Price: Free Works offline: Yes, with limitations Platforms: iOS, Android

What I Used It For

12 countries over 4 years: Portugal, Spain, France, Italy, Japan, Thailand, Vietnam, Mexico, Colombia, Greece, Croatia, Morocco.

Rental car navigation in rural areas. Walking through cities at night. Finding my way back to hotels when I’d wandered too far. Showing taxi drivers where I needed to go when neither of us spoke the other’s language.

How to Download Offline Maps

This is easier than most people realize:

1. Open Google Maps
2. Search for the area you need (city name, region, or just zoom to it)
3. Tap the location name at the bottom
4. Tap the three dots, then “Download offline map”
5. Adjust the area if needed, then tap “Download”

The download saves to your phone. When you lose signal, Maps automatically switches to the offline version.

The catch: You need to be on WiFi (or have a solid data connection) to download. Hotel WiFi before bed is the best time.

What Actually Works Offline

Navigation: Turn-by-turn directions work offline for driving and walking. The voice guidance works. This alone makes it worth downloading.

Search: You can search for addresses, businesses, and points of interest within your downloaded area. Results are less detailed than online, but usually sufficient.

Map viewing: Zoom in, zoom out, move around. The map renders from local storage.

What Doesn’t Work Offline

Transit directions: Public transportation routes require live data. If you’re relying on buses or trains, you need another solution.

Traffic data: Offline maps can’t show real-time traffic. Your estimated driving time is based on typical conditions, not current ones.

Business hours: That restaurant might show on the map, but you won’t know if it’s currently open.

Reviews and photos: Gone. You get the location, not the context.

Real-time updates: Construction, closures, or events won’t appear.

Storage Reality

Offline maps are big. Here’s what to expect:

Area	Approximate Size
Major city (London, Tokyo)	200-400 MB
Small country (Portugal)	300-500 MB
Large region (Southern France)	400-700 MB
US State (California)	600-900 MB

A two-week Europe trip hitting 5 countries might need 2-3 GB of map storage. Budget for this, especially if you have a 64GB phone.

Tip: You can download multiple separate areas. Download just the cities you’re visiting rather than entire countries.

Expiration Issue

Offline maps expire after about 30 days. Google does this because map data changes.

If you downloaded maps for a trip last month and you’re traveling again, check if they’re still valid. The app shows expiration dates in Settings > Offline maps.

You can update maps while connected, which resets the expiration.

Regional Reliability

Works excellently: Europe, North America, Japan, Australia, developed Asia. Detailed maps, accurate addresses, good coverage.

Works adequately: Most of Latin America, Southeast Asia (cities). Maps exist, but detail level varies. Rural areas get sparse.

Works poorly or not at all: Some of Africa, remote areas everywhere. If Google’s online maps are incomplete for an area, the offline version is equally incomplete.

I had issues in rural Morocco where Google Maps showed roads that didn’t exist. The offline version had the same wrong data. Bad source material, bad offline maps.

vs Apple Maps Offline

Apple added offline maps in iOS 17. How do they compare?

Google advantages:

• More detailed in most regions outside the US
• Better search within offline maps
• Longer track record of reliability

Apple advantages:

• Tighter iOS integration
• Slightly better privacy (data stays on device more)
• Works with Apple Watch offline

My recommendation: If you’re on iOS, download both. They’re free. Having a backup when one fails has saved me twice.

vs Dedicated Offline Apps

Maps.me and Organic Maps offer full offline functionality with no download limits or expirations.

Choose them if: You’re doing extended travel in areas with poor data coverage, or you want to avoid Google entirely for privacy reasons.

Stick with Google if: You already use Google Maps, you’re doing shorter trips, and you want turn-by-turn navigation (Google’s is better).

I use Google Maps for most trips and Organic Maps as a backup in remote areas.

Privacy Considerations

Google Maps collects location data. Even offline, it caches your location history and syncs when you reconnect.

If this bothers you, use Organic Maps instead. It’s open source and collects nothing.

For most travelers, the privacy trade-off is acceptable. But know what you’re trading.

Setup for a Trip

Here’s my process before any trip:

3 days before departure:

• Download maps for arrival city (airport area + city center)
• Download maps for any confirmed accommodation areas

Day before departure:

• Verify downloads completed and didn’t expire
• Clear old offline maps from previous trips to free space

At hotel on arrival:

• Download maps for day trip destinations
• Update any maps that need refreshing

This takes 10 minutes total and has saved me hours of confusion.

When to Not Bother

Very short layovers: If you’re not leaving the airport, don’t waste storage.

Familiar cities: If you know London or Tokyo well, skip the download.

Strong data plans: If you have reliable international data, offline maps are insurance you might not need. Though they do save battery and load faster.

Pure transit trips: If you’re only using subways and buses, offline maps help less (transit info isn’t available).

The Bottom Line

Google Maps offline is free, works well, and takes 5 minutes to set up. The feature exists specifically for travelers, yet most travelers discover it only after getting lost.

Download before you leave. Your future self, standing on an unfamiliar street corner with no signal, will appreciate it.
