Apple Tree Bay, in Ku-Ring-Gai Chase national park, has a popular boat ramp for accessing Cowan creek and plenty of parking. The area has kiosk, electric BBQ's, picnic benches, toilets, drinking water, garbage facilities, and shade provided by trees. If you are after a quiet spot, head to the western end (away from the boat ramp, past the BBQ's), just beyond the car park, to a lovely clearing by the water. The area is closed between sunset and sunrise. The kiosk/cafe is open on weekend and services hot and cold drinks, ice creams and some hot food.
