Weymouth and Portland are set to host the 2012 sailing events
Part of the planned coastal path around England is set to open in Dorset in time for the 2012 Olympics.
Environment secretary Hilary Benn said the first stretch of the path would open at Weymouth Bay in time for the "lighting of the Olympic flame".
Weymouth and Portland are set to host the London 2012 sailing events.
The creation of a continuous coastal path will be made possible under the Marine and Coastal Access Bill currently going through Parliament.
It is expected to get Royal Assent by the autumn.
Natural England will consult key stakeholders from next year on how the new path will be delivered.
The 20km (12.4 mile) section in Weymouth is expected to be opened by July 2012.
