Four wrecks lie close to shore in just 6 metres of water, visible from the coast on calm days and accessible by snorkel in good weather. Beyond the wrecks, snorkellers can explore Mushroom Rock — a small offshore island reef 500 m from the boat ramp — and encounter the bay's iconic friendly stingrays that glide through the shallows year-round.
