Start your trip at Central Station in the heart of Sydney's CBD and catch the L90 bus. I'd recommend getting a window seat on the right side of the bus, because it's a beautiful bus ride going by many of Sydney's amazing northern beaches. It's one of my very favorite bus trips, going by all these beautiful beaches. The trip is about 90 minutes by bus, but worth the time due to all the fabulous scenery.
The bus will let you off right on the main road in Mona Vale. It's a short few blocks to the large assortment of shops including the largest supermarkets on the northern beaches (Woolworths & Coles) or a 10 minute walk to Mona Vale beach.
