What is HOHO Bus?

Can you explain me what is “HOHO Bus”?

HOHO Bus Stands for Hop on Hop Off Bus. What it does is that it allows you to visit the best tourist places in Delhi without worrying about missing your bus. Bus service is available at a regular frequency. Once you board these buses you can get down at the tourist attractions you like to see. The best part is that you can see places at your own pace. To go to the next stop simply take the next bus.
