A new online reservation system for tours of the Theodore Roosevelt House in Cove Neck will be available when the National Historic Site reopens in July.

With dates beginning July 15, individual house tour tickets can be reserved up to six months in advance through the website, recreation.gov.

Visitors can purchase up to eight tickets through the online reservation system. Individual tour tickets, as well as unreserved online tickets, will still be available to walk-up visitors. Group reservations will not be accepted until January 2016.

The site known as Sagamore Hill, which is operated by the National Park Service, has undergone a $10 million roof-to-basement overhaul over the past three years and is set to reopen July 13 with public tours.

Along with the new reservation system, entrance fees will increase for the first time since 1993. Visitors 16 and older will pay $10, while admission for children 15 and younger will remain free. The Sagamore Hill Annual pass will increase to $40.

Access to the site grounds and the Old Orchard Museum will remain free.

National Park officials said in a news release the fee increase will help fund a maintenance backlog and complete other improvement projects around the site.

"This modest increase in fees will allow us to continue to protect, preserve and share the remarkable cultural and natural resources here at Sagamore Hill with current visitors and future generations," said Sagamore Hill National Historic Site Superintendent Kelly Fuhrmann. "Even with this small fee increase, a tour of the Theodore Roosevelt House is still one of the best recreation values on Long Island."
