1. Go places
2. Search "google my maps" and click the first link (assuming you have gmail)
3. Click "+ create a new map"
4. Add places. I recommend using layers ("add layer") and color-coding each layer (food, drinks, tourist attraction, etc.)
5. Share the map!
If you would like to see an example I built, search "medium misterrayco traveling to japan", click the second link and scroll halfway down to the section "My Japan Map".
I would love to see maps of your favorite places, or even just your favorite spots in your hometown!
