The surf in front of the chalets have quite a few wavegaricks in the first waves, 15-20m cast while you are on dry sand. Keep that in mind and the rocks on the right have blacktail and karenteen that you can also catch standing on dry sand. maybe you can cast he can hold the rod, quite nice action on very small hooks and squid bait. Took some kids there last year (not 4 years old, yongest was 6) they all casted themselves and between the 4 of them got some 20 plus wavegarrick, blacktails,karenteen (all released to grow big) so they are there. Will you be staying in the caravan park or chalets?
I will be down on the 17th.
