Recently I took an out of state road trip, and during the trip I used Google Maps to look up routes and restaurants on the fly (which can be very useful), but at times it would have been better if I had saved some routes, restaurants, and other points of interest ahead of time. I started wondering about available options to create and save maps with locations for restaurants, hotels, tourist destinations, etc. so when I got home I started looking into how to save maps in Google for later use.
Google has a companion product called My Maps that allows you to create a custom map with various routes and points of interest and save them to your Google Drive. To use My Maps, first open Google Drive, and go to New>More>Google My Maps. My Maps will open in a new tab, with a new map ready to go. Then click Untitled Map to add a Title and Description for your map.
My Maps uses "layers" for different elements on the map, such as driving directions, walking directions, restaurants, etc. The first layer is created by default and is called Untitled layer - to change the layer name, click Untitled layer and then add the name of your layer. You can then add your routes, restaurants, campsites, hotels, tourist destinations, etc. to different "layers" and put them all together to view on one map.
There are travel bloggers out there who are using Google Maps and My Maps to plan trips, so you can find more information and step-by-step instructions on how you can use Google My Maps for travel. Here are a few that I found:
If you have an Android phone, you can open your saved maps on your phone by using the Google My Maps app (this is a separate app from the Google Maps app). For both Android and iPhone, you can open your saved maps in the Google Maps app (go to Your places>Maps).
