Hi mate had some good fun camping and fishing there over the years with my family mate . There a camping shop on the island that sell terminal tackle and bait . You can dig blow lug of the beach but they tend to be small , you better of digging in the estury there some bigger ones there mate. It can be very windy at shell we have had a trailer tent wrote of there in high winds . But if the weather nice it's my fav place in the uk
if the surf is big you will struggle with a spinning rod, but if it's small u will be ok .i had plenty scoolie bass there standing in the surf flicking out a lugworm on a 1 once lead on a spinning rod it's good fun fish low water on the flood there for the bass. I had bass there on popper lures ,and this is the best time of year to do it fish the flooding tide over the rough ground when it's calm .plus if you have a look round the estury you might still get some peller crab fish. This bait in the estury and you will get bass and flounder good luck and let me now how you get on , it's the first year we havent camped there because the summer not been 2 good . Ps there are two fishing shops in Barmouth . Have a good un
