Fathom Five National Marine Park comprises a scattering of uninhabited islands and the waters that surround them at the end of the Bruce Peninsula, offshore from Tobermory. To protect the natural habitat, only Flowerpot Island, 4km from the mainland, has any amenities, with limited space for camping – six sites only – and a couple of short hiking trails that explore its eastern reaches. A delightful spot, Flowerpot takes its name from two pink-and-grey rock pillars that have been eroded away from its eastern shore – and these are readily seen on the islet’s hiking trails.
Fathom Five is known across Canada for its excellent diving – the waters are clear, there are extraordinary rock formations and a handful of shipwrecks. Prospective divers must register in person at the national park office. Diving gear can be rented down by Tobermory harbour at G&S Watersports (519 596 2200, gswatersports.net), who also offer diving lessons and kayak rental.
