I completed a tour of the Tomb on 05/19/19. The cost is about $6 USD for entry, but worth it. This is a unique experience and you can download and listen to an audio guide on your cell phone.
Get there early. It's HOT. The self-guided tour offers an immersive experience to the traveller with the correct mix of history, culture, and myth through professional narration, with background scores of music, qawalli or other sound affects.
There is no need for you to depend on a guide - you can take the walk anytime at your own pace. Actually, one of the groundskeepers approached me wanting to give me a personal tour (for a fee of course.) I said yes, go! He was ok. I couldn't understand him much, so I tipped him about $1 USD.
Humayun’s Tomb is a UNESCO World Heritage site - one of the most splendid Mughal era monuments.
