Not the most well-known attraction in Gibraltar, but surely the most spectacular, this narrow, ancient path with steep steps – many hewn into the limestone – starts at the nature reserve's southern entrance at Jews' Gate and traverses the southern end of Gibraltar before steeply climbing the crag on the eastern escarpment. It emerges on the ridge near O'Hara's Battery.

The views along the way are stupendous; ornithologists won't know where to look first, as birds soar above, below and around you. The 1.5km trail is mildly exposed. Allow 45 minutes to an hour.
