The upgrade of the Bonnie Vale campground has commenced as part of the $2.5 million infrastructure improvement program for the Royal National Park.
The works will include new shelters and barbecues, landscaping and road repairs and is expected to be completed in time for the peak summer season.
National Parks & Wildlife Service (NPWS) closed the popular facility in Royal National Park in September 2018, citing health risks associated with an increasing number of fragments of asbestos emerging from the soil, left over from the demolition of the old cabins on the site.
Heathcote MPLee Evans said the project will help ensure the Royal National Park, the world's second oldest national park, remains one of Sydney's most popular for generations to come.
"Bonnie Vale is very much the gateway to the natural and cultural treasures of the Park - from the scenic Royal Coast Track to the spectacular Aboriginal engravings at Jibbon headland," Mr Evans said.
"The remediation at Bonnie Vale has been a significant project with comprehensive planning including Aboriginal archaeological investigations and environmental assessments to inform the works."
"New shelters and barbecues, improved landscaping and road repairs will make visits a safer and more enjoyable family-friendly experience.
"New works will also include installation of power for some camp sites, and a dedicated area for education and community groups. The amenities block has also been fully refurbished and is now as good as new again." Mr Evans said.
The works at Bonnie Vale will require temporary closures to ensure visitor safety during the peak construction periods. This may impact pedestrian access to the day use area, the beach and pedestrian access between Maianbar and Bonnie Vale with part-time closures.
The community can check the NPWS alerts and onsite signage for project updates and any proposed access changes.
Bonnie Vale has been a popular holiday destination since the 1930s and, up till the 1950s, the area contained more than 170 cabins and 500 campsites.
Subject to public health orders, NPWS is looking forward to reopening the campgrounds for visitors by the end of 2021.
