The mouth is on the north side so less walking from that side. From either side you can access the lagoon. I fish from the south side but purely because I live nearby plus more access points to the lower river. Plenty of trout about in the lagoon and river, not sure how the mouth itself has been, I haven’t had much luck with spinners lately, althou alot of follow ins, but Kevo85 seems to be. Good luck and let us know how you get on.
