Time Out says
Walk the Wormhole and discover a glimpse of Sydney's past
Affectionately known as the ‘Manly wormhole’, it was in fact industrious fishermen – and not natural erosion – that chiseled this 40-metre channel through the rock of Queenscliff Head more than a century ago. Connecting Queenscliff and Freshwater beaches, the tunnel is still the most direct route between the two seafronts without cutting through the suburban streets, and is something of a local secret – you won’t find signposts or boardwalks to help you reach it. While it may be a bit of a challenge scrambling over the rocks of the headland north of Manly Beach to find it, your efforts are soon rewarded with a close encounter with Sydney’s rich history and a view of Freshwater Beach that’s hard to beat, especially if you time your visit to coincide with sunset.
