The Rock of Gibraltar, a British Overseas Territory, is a monolithic limestone promontory offering stunning views and historical significance. Accessibility varies, with some areas reachable by cable car, taxi, or organized tours, while others require significant walking, potentially challenging for those with mobility issues. Both solo and guided visits are viable, with guided tours providing deeper historical context and access to restricted areas like St. Michael's Cave. The best time to visit is during the shoulder seasons (spring and fall) to avoid peak tourist crowds and extreme weather. Expect to spend at least half a day exploring the Rock, with costs including entrance fees to the nature reserve and transportation. Be aware that the upper Rock is a nature reserve with monkeys; visitors should avoid feeding them.
