A new toilet block is among the improvements planned for the car park at Compton Bay.
National Trust, which runs the site, wants to change the layout, to make it safer and easier to access.
Proposals, for next year, also include making the space greener.
The Trust is planning to use natural materials to help mark out car parking spaces, and will improve entry and exit to the site, including improvements to visibility along Military Road.
The plans include replacing the crumbling tarmac area with a new green space, so that people can use it to enjoy cliff-top views, and safely access the food and beverage areas, without the worry of moving traffic.
As part of the investment, the car park will have an improved entry point and a mini round-about will be created within the site to help with traffic flow.
As well as changes to the layout, the charity also plans to improve visitor facilities with a brand-new toilet block.
This is being carefully designed in a modular fashion, allowing it to be relocated if and when cliff erosion requires it.
The design of the new block uses sustainable techniques to keep its environmental impact low. This includes as little ground works as possible, and solar energy for lighting.
Senior Programme Manager, Ben Savill said:
“We hope the improved facilities will encourage visitors to not only enjoy the beauty of Compton Bay beach but also to explore the wildlife-rich Compton Downs area and to discover the work we are doing here to improve the land for nature.”
The improvements are planned to take place during 2023, although this is dependent on planning approval.
