Scuba diving and snorkelling is a popular past time in Bremer Bay with some of the best hard and soft coral diving on the South Coast. The Bremer Bay coastline consists of exposed granite headlands separated by small curved bays and sandy beaches.

Dive Trail

A designated dive trail is located off Little Boat Harbour which is located on the Point Henry Peninsular. The dive trail is a very popular shore dive with a depth ranging from 3 to 10 metres, which allows for good bottom time to explore the trail at your leisure. The trail is made up of 13 concrete blocks with a photo of a local marine plant or animal on one face and informative text about the species on the other. If the diver looks closely in the vicinity of each plinth they will usually find the species described in by the picture and text. The main function of the Dive trail is to educate divers and snorkelers about what they are looking at in the pristine marine environment around the Bremer Bay coastline. The clean clear conditions of the waters in this area are ideal for some unique marine life. Schoold of 'old wives' and zebra fish abound, along with nudibranch, sea dragons and the odd banded coral shrimp.

Back Beach Bommie

The 'Back Beach Bommie' is a collection of granite boulders and slabs found two hundred metres off the southern end of Back Beach. Measuring approximately a hectare in size it provides gutters, vertical faces, swim throughs and overhangs. Each aspect of this site provides something different owing to its varied facing directions. The vertical faces have prolific sponge growth miced with gorgonian fans, nudibrach's, ascidians, tube worms, basket stars, bryzoan corals, soft coral and in particular large areas of Tubinaria hard corals. The depth here at 11 meters allows excellent sunlight penetraion for the many plants that rely on photosynthesis, in the same manner as terrestrial plants. Back Beach Bommie has both shallow sunlit portions, interspersed with shaded overhangs and crevices providing for the varied needs of the species found there. The boulders provide places of attachment for larger plant species such as kelp. The surrounding sand area of the Bommie is perfect for sea grass to proliferate.
