Mount Martha Beach stretches 2 km along the calm shores of Port Phillip on the Mornington Peninsula, dotted with iconic colourful bathing boxes that make for a picturesque snorkelling backdrop. The gently sloping sandy beach leads to shallow, sheltered waters protected from ocean swell, with a depth range of about 3–5 metres. Several creek gullies provide easy track access to the water. The beach is split into northern and southern sections; the area near the surf lifesaving club offers the best facilities. Snorkellers can explore sandy bottoms with seagrass beds and rocky reef patches near the points, with clear visibility best on calm, high-tide days in summer.
