Sambro Bridge

Sambro Bridge in Nova Scotia is an advanced dive site near the historic Sambro Island Lighthouse, the oldest operating lighthouse in the Americas. The underwater terrain features dramatic rock formations with strong tidal currents creating a nutrient-rich environment. The bridge — a natural rock arch connecting submerged formations — gives the site its name and provides a spectacular swim-through at depth. Dense cold-water communities thrive on the current-swept rock, with massive anemone colonies and prolific sponge growth. Large Atlantic cod, wolffish, and lobsters inhabit the deeper sections. The challenging conditions and rich rewards make this a bucket-list dive for Nova Scotia enthusiasts.
