Barrington Tops is part of the Mount Royal Range, a spur of the Great Dividing Range. Barrington Tops is a plateau between two of the large peaks in the range. The park is believed to be an extinct volcano and the mountain ranges are made up of a mixture of sedimentary rocks with a granite top. Erosion has weathered the granite and rounded granite boulders can be seen in some areas of the park. Estimates put the age of the rock at 300 to 400 million years, well before Australia separated from Gondwana.
Climate
The climate varies from temperate on the lower altitudes to subalpine at highest elevations. A record low of −17 °C (1 °F) has been registered at 1,500 m (4,900 ft) above mean sea level.[5] Rainfalls fluctuate between 750 millimetres (30 in) in the northwest to more than 2,000 mm (79 in) in the southeast.[6]
Flora
The ecology of the national park varies from subtropicalrainforests in the gullies to subalpine and alpine regions on the mountain peaks. Snow usually falls on the mountain peaks every year and occasionally snows enough to close roads. Rainfall can exceed 1,500 mm (59 in) per annum.
A large variety of plants and animals reside in the park and the steepness of the terrain ensures that they are not disturbed by humans. Plant life includes a large variety of eucalypt trees including Snow Gums, subtropical and temperaterainforest trees like Antarctic beech, tree ferns, a large variety of mosses and ferns and a wide range of edible plants such as the native raspberry, the native cherry and the lilli pilli.
In 1969 the area between Mount Barrington, Mount Royal and the Gloucester Tops was declared the Barrington Tops National Park. In 1986 it was listed as a World Heritage Area and subsequently a Wilderness Area. Some of the rivers flowing through the Barrington range have been classed as wild rivers meaning they are exceptionally pure and unpolluted. The highest peak is Brumlow Top which rises to a height of 1,586 metres (5,203 ft).
Aircraft crashes
A number of aircraft have crashed in and around the Barrington Tops, Aeroplane Hill being named after one of the crashes.[9] The altitude, frequent fog & cloud, storms and cold weather (causing icing) make this area potentially hazardous to aircraft. One article refers to the "Devil's Triangle".
The Barrington Guest House was built from 1925 on the upper Williams River near Barrington Tops by Norman T. McLeod, licensee of the Royal Hotel in Dungog, using timber cut and milled from the property. It stood on land consisting of 10.5 hectares (26 acres) of forest surrounded by National and State Parks and was officially opened in 1930 by Leader of the Country PartyEarle Page. During the opening there was some 200 guests that attended.[25]
The guest house was a popular venue for people to stay in the park, until it burned down in a fire at 11pm on 24 September 2006 due to an electrical fault.[26] The fire was not regarded as suspicious.[27] It was undergoing modernisation under new ownership at the time of the fire. There are plans to rebuild, but no significant process has been made, and only part of the old chimney remains on the site. [28] The guest house has undergone many different owners in its history; Mattara Investments that traded as Barrington Guest House and bought the premises in 1976. Due to business troubles however, it was then placed into voluntary administration in 2000, after which the business was than taken over by David and Susan Eissa in February 2002.[29] Only one more owner has been known since (according to the now defunct website); Purchased in January 2004 by Natalie Day and Tony Horley. [30] In April 2024, the site was purchased by a group of previous guests and owners who are making it safe to enable future visitation (2025).
