The path offers views over the Strait of Gibraltar, Windmill Hill, Europa Point, the Great Sand Dune, Gibraltar's east side beaches, the Mediterranean Sea and the Spanish Costa del Sol.

It is located near the southern end of the Upper Rock Nature Reserve, adjacent to Lord Airey's Battery. It was named after the Governor of Gibraltar, General Sir Richard Airey.

The Rock of Gibraltar (from the Arabic name Jabal Ṭāriq جبل طارق) is a monolithic limestone promontory located in the British territory of Gibraltar, near the southwestern tip of Europe on the Iberian Peninsula, and near the entrance to the Mediterranean. It is 426 m (1,398 ft) high. Most of the Rock's upper area is covered by a nature reserve, which is home to around 300 Barbary macaques. These macaques, as well as a labyrinthine network of tunnels, attract many tourists each year. The Rock of Gibraltar, one of the two traditional Pillars of Hercules, was known to the Romans as Mons Calpe, the other pillar being Mons Abila, either Monte Hacho or Jebel Musa on the African side of the Strait. According to ancient myths fostered by the Greeks and the Phoenicians, and later perpetuated by the Romans, the two points marked the limit to the known world, although the Phoenicians had actually sailed beyond this point into the Atlantic, both northward and southward.The Mediterranean Sea surrounds Gibraltar.

Dudley Ward Way is a road tunnel through the south-eastern part of the Rock of Gibraltar. It is named after Sir Alfred Dudley Ward, Governor of Gibraltar from 8 June 1962 to 5 August 1965. The road running through the tunnel links the eastern side of The Rock (including Catalan Bay and Sandy Bay) via Sir Herbert Miles Road, with Europa Point, at the southern tip of Gibraltar via Europa Advance Road.

O'Hara's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located at the highest point of the Rock of Gibraltar, near the southern end of the Upper Rock Nature Reserve, in close proximity to Lord Airey's Battery. It was constructed in 1890 at the former site of a watchtower that had earned the name O'Hara's Folly. The battery and tower were both named after the Governor of Gibraltar Charles O'Hara. The first gun mounted on the battery was a 6-inch breech loading gun, which was replaced with a 9.2 inch Mark X BL gun in 1901. The battery was in use during World War II and was last fired during training exercises in 1976. O'Hara's Battery has been refurbished and is open to the public. The battery and its associated works are listed with the Gibraltar Heritage Trust.

O'Hara's Tower was a watchtower in the British Overseas Territory of Gibraltar. It was located at the highest point of the Rock of Gibraltar, at what is now O'Hara's Battery, near the southern end of the Upper Rock Nature Reserve. Initially known as St. George's Tower, it was constructed in the late 18th century on the order of then Lieutenant Governor Charles O'Hara, under the presumption that it would be useful in observing the enemy at the Port of Cadiz. Not only was it unsuccessful; it was struck by lightning shortly after it was built, and remained in ruins for much of the 19th century until its demolition in 1888. Formerly referred to as St. George's Tower, it came to be known as O'Hara's Tower or, frequently, O'Hara's Folly.

Located on the east side of Gibraltar, on a former World War II ammunition jetty, the Gibraltar Wave Farm is the first commercial, grid-connected wave energy power station in all of Europe. The project utilizes the devices of Eco Wave Power Ltd, an Israel-based wave energy company. The wave farm was initially launched with an estimated peak capacity of 100 kW in April 2016 and plans for expansion to 5 MW within the next years. The project is operating through a 25-year PPA (power purchase agreement) between Eco Wave Power, the Government of Gibraltar, and the Gibraltar Electricity Authority. Upon completion, it is expected generate 15% of the total electricity consumption of Gibraltar. The project is funded, in part, by the 2014-2020 European Regional Development Fund, in order to put the country in line with the EU's renewable energy goal: 20% energy generated from renewable power by 2020. The project is also funded by private investment groups. As of February 2018, the Gibraltar Wave Farm accrued 15,000 grid connected hours (and counting), a new world record for wave energy plant.
