I was bowled over when I discovered this mesmerising trail so close to the hustle and bustle of Main Street. The highlight of the walk - so long as you have a head for heights - is the footpath that leads up the sheer, southern face of the Rock, popularly known as Mediterranean Steps. This giddy path has recently been restored by the Bonito Trust and you'll be marvelling at the derring-do of those who built it.
