The water a Oliphant is normally 2 feet deep for a 1 km. Did you guess what happened? Olihpant could be known as one of the largest beaches of the world. The main harbour had to be dredged so small boats could go to their cottages or for fishing.
This is a great place for a Lake Huron red sunset. Also, the fishing islands protect the bay and water is shallow. What this means is warn water in June and calm water for sailing of small boats.
Howdenvale does have sand but is not the best beach. It is known for fishing and a good public boat launch. There is only one L shaped channel out through the fishing islands. Getting out and back is impossible without a map.
