A day on the carp flats is similar to a saltwater trip. Bring all the standard fare: polarized sunglasses, sunscreen, lightweight clothing, rain jacket, fishing license, comfortable shoes, etc. I’ll have a Yeti cooler with ice for whatever food/drink you want to bring.
You don’t need to bring any fly fishing gear at all as rods/reels/leaders/tippet/flies are included. That said, if you have a 6 wt you love dearly or a fly pattern you really wanna try, go ahead and bring ’em.
In terms of prep, the absolute best thing you can do is practice your casting. If you can land the fly quietly inside a virtual hula hoop at 25 to 40 feet with two false casts, your odds of success will increase greatly. If you can do that at 50 feet you may well get some additional shots. If you can do that into a 10 mph headwind, even better.
While I don’t agree with everything in this link, you can swap out redfish for carp and it’s a really solid list to review prior to your trip.
Carp on the fly are never easy, sometimes they’re just less difficult. My goal is to ensure you have fun, learn as much as possible and stick some carp!
