The Entrance is located 100km north of the Sydney CBD by car and takes around 90 minutes to drive there. The area is popular with locals and tourists and the weekends can be a very busy time for the small town center and areas around the lake.
The Entrance is thus named as it is the entrance from the Pacific Ocean to Tuggerah Lake and features a bridge across the lake forming part of the Central Coast Highway.
You’ll also find flocks of birds hanging around the beach everywhere. They actually have daily feeding of the Pelicans which is kind of cool. You can find more info about that in this link.
