Park at the Rotunda and walk is across the bridge and you'll see the entrance to the walk on the right. This walk consists of sand, dirt, stairs and a boardwalk. It has a few lookout points to see the Lakes and a few places you can go off the trail to go to the beach. When you get to the houses and jetty there's a public BBQ and toilets (hole in ground). Keep walking past this and you'll end up at the Entrance.
