When you find a walking route on Google Maps, can you tell whether it is climbing up or going down?

A google search of "Google maps elevation" brings you to
OR
Google Maps elevation for a route
Then you can compare the altitude of the point of a route.
For developers, these websites basically use The Google Elevation API or Google Maps Javascript API V3 Reference: google.maps.ElevationService class.
Another option (which might not work everywhere in the World) is to click on the pedestrian icon:
The above shows that from North Downs Way at 161 ft it is 466 feet uphill to 627 ft at Zig Zag Road.

This is a feature which was added in the last year or so (so much later than when the question was asked). It works for walking and biking routes.– aleSep 27, 2017 at 13:02
