Parks and reserves Pennant Hills is surrounded on two sides by large swathes of bushland. To the east, the suburb is bordered by the upper reaches of the
Lane Cove River and its associated
national park, whilst in the north-west, Pennant Hills borders
Berowra Valley National Park. Both of these reserves contain extensive walking tracks within the boundaries of the suburb, with some linking to the
Great North Walk. Pennant Hills also contains many public parks, the largest being the Pennant Hills Park sportsground. This complex hosts many sporting facilities consisting of the Ern Holmes Oval for Australian Football and cricket, tennis and netball courts, a rugby union field, a football pitch, two hockey fields and an archery range. The Ern Holmes Oval was the home ground of the
Pennant Hills Demons Australian Football Club until 2011. Lilian Fraser Garden is also located in Pennant Hills. Originally maintained for many years by the noted government biologist Dr Lilian Fraser, after her death in 1987 her collection of rare and exotic plants was passed on to Hornsby Shire Council. Open free of charge to the public for viewing, the garden can also be hired for special events for a fee.
Sport and leisure Pennant Hills, due to its wide array of sporting facilities, plays home to a large number of sporting organisations. These organisations include the Pennant Hills Football Club, which was established in 1957, and the Pennant Hills Demons AFC, which has seen nine players go on to compete in the
AFL. Although the Ern Holmes Oval is no longer the home ground of the Demons premiership team due to its size, many of the club's junior teams still compete in Pennant Hills. Pennant Hills is also home to the Baden Powell Scout Centre, which borders the
Lane Cove National Park. Opened in 1929, it initially served as a permanent camp for the unemployed during the Great Depression, and was visited by the
Lord Baden-Powell himself in 1931. Situated on 36 acres of bushland, the centre is now home to the John Hill training centre and provides accommodation, catering and conference facilities for large groups, as well as activities such as high-ropes and rock climbing for camps. The Pennant Hills area is home to the Pennant Hills Cherrybrook Rugby League Club affectionately known as the Stags. Whilst originally based at Pennant Hills Park, the club now plays out of Greenway Oval at Cherrybrook. The club competes with distinction in the North Sydney District Junior Rugby League competition. The Pennant Hills Park Tennis Centre is now part of Northwest Sydney Tennis. It has 16 floodlit courts and a number of social tennis groups, including the Soldiers Point Tennis Club. ==Churches==
