The oldest lighthouse in New York State, completed in 1796, will remain open during exterior work, says Henry Osmers, the lighthouse historian. Osmers says that the exterior of the lighthouse tower is being scraped and repainted with a more weather-resistant paint. Visitors can climb the tower's 137 iron steps for a 360-degree view of the surrounding land and waters, visit the museum and browse the gift shop. Osmers says that in addition, a two-year project is scheduled to begin in September to reinforce the rock sea wall, also known as a revetment, that protects the structure from erosion. montauklighthouse.com, 631-668-2544.

Group boat tours are once again available to the tiny island light station in Long Island Sound near Sands Point, says Craig W. Morrison, president of Historically Significant Structures. The non-profit corporation bought the island in 2009 from the federal government and is raising funds to restore and preserve its historic lighthouse. To arrange for a tour, email Morrison at morrisoncraig@yahoo.com. Morrison's organization also books overnight stays in the keepers quarters. By special permission, guests can stay in the adjacent lighthouse tower, erected in 1849. ($250-$350/night) Overnight guests are provided air mattresses and potable water, but need to carry in almost everything else. Be forewarned: some say the lighthouse is haunted by the ghosts of patriots drowned by the British on its rocks. lighthouserestorations.org, 215-906-5103.

The lighthouse is open to the public again after a two-year renovation of its foundation, according to the Huntington Lighthouse Preservation Society website. The renovation also added a new lighthouse landing platform to the light station, which has stood since 1912 at the entrance to Lloyd and Huntington harbors. One-hour guided boat tours to the lighthouse are available this summer. They leave from 11 a.m. to 3 p.m. on June 30, July 14, Aug. 11 and Sept. 8, from Goldstar Battalion Beach in Huntington. The annual music festival, which is held atop the lighthouse and can only be attended by concertgoers in watercraft, has been canceled for 2019.huntingtonlighthouse.org, 631-421-1985.

The lighthouse, so-named because of its odd shape, is open for boat tours run by the East End Seaport Museum in Greenport. The tours are narrated by Greenporter Bob Allen, whose great-grandfather was the island's last live-in keeper. Visitors can enter the lighthouse, walk around on its first and second floors and stroll the wrap-around deck for views of Peconic Bay.
