Today, Point Lookout has become a popular location for summer residences. Among its inhabitants, it is commonly referred to as "PLO".

Point Lookout is located at the east end of Long Beach Barrier Island. It is adjacent to Lido Beach, which in turn abuts the city of Long Beach, to the west. Point Lookout covers a total area of 0.27 square miles (0.70 km), all land.

Long Beach Barrier Island, which lies between Reynolds Channel and the Atlantic Ocean, was originally formed by glacial deposits and includes a variety of bays, dunes, ponds, marshes, and ocean shoreline, which supports a complex ecosystem that includes a wide variety of flora and fauna. Jones Inlet separates it from Jones Beach Island.

Point Lookout's first known inhabitants were Merrick (Meroke) Native Americans, a tribe of the Algonquin people. The first European settlers in Point Lookout were Dutch, who arrived in the 1640s, followed by the English, in the 1660s.

In 1906, Senator William Reynolds of Brooklyn led a consortium that purchased the entire barrier island. In 1918, Nassau By the Sea was nearly wiped out by fire. In the 1920s, Senator Reynolds established Point Lookout Inc., which brought in concrete streets and divided the community into small plots which were sold to families for approximately $2,500 a parcel, giving rise to the Point Lookout community. Those bungalows that had not burned in Nassau By the Sea, as well as others from other marsh islands, were moved to Point Lookout and can be seen around the community today. The barrier beach on which Point Lookout sits has been, in one incarnation or another, there for hundreds, if not thousands of years. The first mention of Point Lookout begins to appear in the mid-19th century, as a location for whalers, and as a dangerous spot for ships. A United States Life-Saving Service Station was established at Point Lookout in 1872; ironically, it was due to the tragic wreck of the ship Mexico on January 2, 1837, that a U.S. Life Saving Station was created; the service remained there until farmers grew salt hay on the marshes that stretch behind the site.

A series of hotel and seasonal bungalows was built, as was a seasonal railroad connecting Point Lookout to Long Beach, but nearly all these structures were destroyed over time by either winter storms or fire. During the summer months ferries from the Woodcleft Canal in Freeport brought hundreds of day-trippers to Point Lookout's beaches, and for those who lived in Point Lookout, or in the small community to the east called Nassau By the Sea, the barrier island was a paradise.

During the fall and winter of 2018, with the beach undergoing construction, the Pavilion was torn down.

Point Lookout has small homes, densely packed into very small plots, and does not have sanitary or storm sewers.
