How is Monticello funded?

There is a more extensive tour for $60. Very much worth it!

It's a private non-profit foundation that runs on donations, admission sales, and retail sales.

I believe it's 25$ fee for the while day

$25 entrance fee to see the house or walk the grounds.

There is a small fee they charge.

Thank you, All, for your input; however, Chris Morris, your answer is the detail I sought. A big thank you to you!
