+1 for what handyman said .. walk up approx. 1km toward the river mouth.. stop and set up when u see the big sandbank poke out. .. If there is no one there I prob would not go out . .. plenty of room to launch etc.. normally people there to assist .. Check the Leeuwin Lighthouse reading for current wind strength .. Check Margaret river on seabreeze.com for forecast but add a few knows to the forecast wind strength.. Ideal wind there is South East .. which is early this week .. I will be there !!! may catch you !!
Thanks again. It's not looking good for me to get out until the weekend, hopefully not too many people out on the long weekend.
Cheers
