Manly Warmhole/ Queenscliff Tunnel. A moderate level rock hopping from the rock cliff above the Queenscliff rock pool will take you this tunnel that seems like a passage to another world. Apparently, It’s not a natural waves-made tunnel as one would think but it’s the one made by fishermen eons ago who wanted to avoid having to climb around the rocks to get between Freshwater Beach and Queenscliff and Manly Beaches. P.S: Don’t Follow Google maps for this! It’ll take you nowhere! Always follow the route along Queenscliff rock pool and you’ll be in this warmhole in less than 5 minutes.
