The Northern Beaches of Sydney refers to a suburban district located in the north east of the city, as well as a stretch of famous beaches extending northwards from Sydney Harbour and North Head at Manly to Barrenjoey Point and Broken Bay, fronting the Pacific Ocean.
Located on the hilly areas and plateaux immediately behind the beach suburbs, are the so-called "forest suburbs", so named because of the large tracts of natural bush land which feature in this area. These include:
Frenchs Forest - The major centre of the forest area.
Terrey Hills - A quier suburb with a laid back community
The Northern Beaches is surrounded on all sides by either water or forest areas, causing some locals to call the area "the Peninsula".
Northern Beaches is a "family-orientated" area and topless bathing is generally not the norm; it still occurs in Manly, but is less common than at the beaches on the other side of the Harbour such as Bondi, Tamarama, etc.
Manly Beach is the most popular destination for tourists and visitors, with a range of attractions and activities aimed at the day tripper and holiday maker. In reality, there is so much more the Northern Beaches has to offer than this tiny southern portion and less tourists and crowds will make it more enjoyable.
There are only three ways to get to the Northern Beaches by car. The first route is the Spit Bridge from Mosman (Military Road/Spit Road). The second route is across the Roseville Bridge (Warringah Road), from Chatswood. The third route is via Mona Vale Road, which comes from Pymble/St Ives.
Running north to south along the beaches, the main road artery is Pittwater Road/Barrenjoey Road. Another major road, connecting the north and south through the Forest area, is Wakehurst Parkway, which offers a beautiful drive through natural bushland.
The spit bridge is a gridlock point for traffic. Many commuters try to use the T3 (transit 3) lanes, which are for carpooling. Northern beaches carpools are also available .
The Northern Beaches is famous for its beaches, each with its own distinctive character. Northern Beaches buses ply the route between Manly and Palm Beach, passing all of the ocean beach suburbs along the route.

Cricket. Manly also has a grade cricket side which plays at an oval in Manly itself during the summer season. Grade cricket is essentially a feeder competition for the Pura Cup competition (still regularly referred to as the Sheffield Shield), and top Australian players rarely play at grade level.
Rugby Union. The Northern Beaches boast two main rugby union sides: Manly , based in Manly itself, and Warringah (affectionately known as 'the Rats'), based in Narrabeen
Most Northern Beaches suburbs have small shopping villages oriented towards locals and their needs.
Warringah Mall, located at Brookvale, and one of Sydney's largest shopping monstrosities, with most of the major retail outlets. It is also unique in Sydney as an "indoor/outdoor" shopping centre, reflecting the outdoors lifestyle of the Northern Beaches.
Warriewood Square, located in the Warriewood Valley (much more dull and tacky).
Dee Why has a major strip of shops, while Manly caters mainly for tourist and leisure shoppers. Harbord (Freshwater) has some quiet, but an interesting group of shops where you can buy localised souvenirs such as stickers and beach gear.
