Start at the southern most point of the Bowman Bay/Rosario Beach Trail
and take the hard right leading to the west, which will loop around and immediately open up onto a double sided beach between Bowman Bay and Lottie Bay.
Run on the path just above the sandy beach where the earth gives better footing. As you reach the forest, the trail will head to the left. Follow the trail up and over some rocks before it drops and heads due south. Soon you'll emerge from the trees with fantastic views of the ocean.
The trail loops around to the western side of the "island" with amazing views before reentering the trees. Soon the trail will make a sharp right and head down for a short while to close the loop.
