Glenmont Estate - Due to ongoing project work at the estate, we are unable to give an exact date for the mansion to open to the public. We hope to know more soon. Please contact us for updated information by calling the park visitor center @ 973-736-0550 ext. 11.

HOWEVER: While we are closed for work at the estate, we have established 3 days in May that we will open the grounds and home to the extent that the projects will allow. Glenmont will be open Sunday May 5th, Saturday May 11th, and Sunday May 19th from 11am - 4pm (last entry into the house will be 3:30pm).

Important Note: You must pay your entrance fee and pick up a car pass at the Laboratory Complex Visitor Center at 211 Main St., West Orange, NJ before going to Glenmont. Llewellyn Park is a private community and vehicle passes are for visiting the Glenmont Estate only.

Please call the Visitor Center at 973-736-0550 ext. 11 for updated information.
