Rock of Gibraltar Tunnels and Caves
After a quick but thrilling ride up The Rock on the cable car, a breathtaking panorama of the bay opens up before you. You will then follow a wooded path to St. Michaels Cave, a network of limestone caverns nearly 1,000 feet above sea level. Continue to the formidable Princess Caroline's Battery and the entrance to the World War II tunnels. Within a land area of only 2.6 square miles, Gibraltar has 34 miles of tunnels, built over nearly 200 years, primarily by the British Army.
