Admission fees for National Trust Historic Sites

A review of admission fees at National Trust Historic Sites shows that they range from a low of $4 (Hotel de Paris Museum) to a high of $25 (Glass House), not counting five sites that are free. The median fees are $11 for adults (general admission), $8 for seniors, and $4 for children. Who qualifies for those discounted rates is inconsistent, especially for children, whose ages are variously defined as K-12, 5-17, 6-12, 6-14, 6-16, 6-18, and 11-18. Discounts for other visitors, such as AAA members, military, or groups are rarely used. For more details, review the entire chart (it’s always available on the Reference page).
