There is one concrete ramp with enough room for two boats to be either launched or received. There's no charge for parking, but it does get busy on days of good weather – especially during holiday periods.
The Old Dunsborough ramp is in close proximity to the town of Dunsborough which will have any supplies which you should need.
The Old Dunsborough ramp has been upgraded in the last few years. With this said, it is nowhere near the best ramp in close proximity to Dunsborough for larger boats (this award goes to Quindalup). However, when the conditions allow this is a great alternative for smaller vessels. Care needs to be taken when launching/retrieving of the submerged rocks which are located either side of the ramp - these can be an issue as there is no finger jetty when boaties are waiting to head out or retrieve.
