The Panmure Island Lighthouse is 17.8 m (58.4 ft) in height from base to vane. The Lighthouse is octagonal in design; the first octagonal lighthouse built on Prince Edward Island, though many were to follow. The four storey Lighthouse is made of wood with a shingled exterior and a masonry foundation. The white Lighthouse has a corbelled cornice, brackets beneath the lantern deck and pedimented caps over the doors and windows. In 1908, the Department of Transport built a fog alarm building and installed a fog alarm that operated by diaphone and compressed air. When the Lighthouse became automated in 1985, a generator room was constructed on the first floor of the Lighthouse. The fog alarm equipment is now also housed there. There is also a light keeper's dwelling that was constructed in 1957. The dwelling has been sold to the daughter of a former keeper. Margaret and Roger MacLeod now operate the Lighthouse on behalf of the Panmure Island Lighthouse Association Limited. Over the years, there has been an earlier dwelling, a number of sheds, a barn and the 1908 fog alarm building located on the property. The fog alarm building was removed when the light became automated.

The Panmure Island Lighthouse has seen a number of light keepers over the years, several from the same family. Andrew MacDonald moved to Prince Edward Island from Scotland in 1805 and bought all 800 acres of Panmure Island. He built the first brick house and stable on Prince Edward Island. In 1853, his son, Archibald, sold one acre and access to the lighthouse for £20. Archibald's son, William Archie, tended to the light from 1887 till 1908. In 1908, Mathias Condon was appointed fog alarm engineer. In 1910, Wallace E. Graham was chosen for the position of light keeper. He took over from Colin Steele who had resigned. It is unsure when William Archie's son, William Albert, took over as keeper of the light but it is known that he retired in 1936. Charles A. Steele then took over as light keeper but died three years later. Augustine Jamieson was made temporary fog alarm engineer, a position taken over by his son Louis when Augustine died in 1940. George Creed was also appointed lighthouse keeper. In 1960, William J. MacDonald, the last light keeper, began tending to the light. He was off the job for two years when the lighthouse was downsized to one keeper. MacDonald. however, came back and was keeper of the light until 1985 when the lighthouse became automated.

The Lighthouse is well known to both local residents and visitors to Prince Edward Island. An adjacent beach and the Panmure Island Provincial Park draw many people to the region in the summer months and make the lighthouse a highly visited spot. The Panmure Island Lighthouse is also featured in Government of Prince Edward Island Tourist Literature and is a suggested stop. In 2002, Panmure Island Lighthouse was on the cover page of Prince Edward Island's Visitor Guide.
