Alright mate?
Mac is right, Shell is your closest spot. Not the cleanest beach in the world but when it's going off there really is nowhere like it. Clean set-up/pack down area, huge shallow area when the tide goes out, messy chop with a few nice waves thrown in, a couple of little flatwater spots for getting some great speed runs in.
All that and because of the previously mentioned cleanlines issues it basically amounts to the kitesurfers very own private beach!!!
It's accessed through the Shell Bay caravan Park, buy a parking day pass for £1(lets you use toilets) and get them to direct you where to go if there aren't any kites already visible. Note that the caravan closes from Nov-Mar and the beach is best accessed through Drumeldrie between these times
Hope this helps
