You enter the grounds by the main gate on U.S. 9, just north of the village of Hyde Park. You leave the site by the north drive and gate on U.S. 9, near St. James Church. The exit drive affords fine views of the Hudson River and the mountains to the west.

The grounds are open every day from 9 a.m. until dark. You are welcome to spend as much time as you wish viewing them.

The mansion is open every day during the summer, June 15 through Labor Day. It is closed Mondays at other seasons, and on Christmas Day. Visiting hours are from 9 a.m. until 5 p.m. The nominal admission charge to the mansion does not apply to children under 12, nor to groups of elementary and high school children, regardless of age, and accompanying adults who assume responsibility for their safety and orderly conduct.

A self-guided tour system enables you to begin your tour of the mansion immediately upon arrival. Special guide service for groups may be arranged in advance through the superintendent.

There are no accommodations for picnicking or dining at the site. These services are available in the village of Hyde Park and at Norrie State Park, 4 miles north. Overnight accommodations are available in the village.

The Home of Franklin D. Roosevelt National Historic Site, administered jointly with this site, is 2 miles south of the village of Hyde Park on U.S. 9. It is open at the same times as Vanderbilt Mansion.
