Is the tajmahal in Mumbai also can u go inside it?

No. It is located in Agra, Uttar Pradesh. You can go in inside with proper ticketing. Taj Mahal is an ivory-white marble mausoleum on the southern bank of the river Yamuna

Taj mahal Is in Agra, Delhi

No it is in Agra,Uttar Pradesh. Yes you can go inside  

No, Its in agra. You can go inside parts of it.

I prefer the Taj Mahal in Goa. A museum? I thought it was an 'otel!

Yes you can go inside but you should line up early in the morning so you can avoid the heat from the afternoon sun. 

It also doesn’t smell like what you smell when riding Soaring at Epcot. 

It'a Mosque too and it's in Agra.

ps, Yes, you are allowed to enter most parts, and see the two  ( empty ) tombs there, but  probably not the real ones in the basement below them.

ps, The Taj Mahal is 1,206 km from Mumbai.
