A flats grand slam involves catching a bonefish, permit, and tarpon on the same day.
These three fish are some of the most popular targets for saltwater fly fishers visiting areas with good flats fishing.
While it is well known among saltwater fly fishers, what constitutes a flats grand slam it is handy to know it is officially set down by the International Game Fish Association (IGFA) as “catching the following species on the same day: bonefish, tarpon, and permit“.
Catching all three plus a snook on the same day is referred to as a Super Slam.
There is no defined size for each of the fish in the flats grand slam. What matters is the same angler catching all three on the same date.

Tips on Catching a Flats Grand Slam
You need luck on your side to catch the flats grand slam, also known to some anglers as an inshore grand slam.
But there are some things you can do to maximize your chances.
The first is to choose your location carefully. The above list provides a good starting point of destinations where many anglers have caught a flats grand slam and there is good fishing for each of these species.
Our second tip is to get used to casting in the wind. Flats fishing means you’ll often be dealing with strong winds. Couple this with the need to deliver accurate and well-timed casts to finicky permit or fast-moving tarpon and you can understand that it is far from easy.
Before you embark on your trip practice casting in the wind. Not just distance but accuracy too. And not just pushing up directly into the wind, but changing the direction of the cast even with a decent breeze blowing.
And finally, be flexible. Rather than setting out to catch the fish in a particular order, embrace the chaos of flats fishing – no two days are the same and things can change from hour to hour.
Generally speaking, bonefish are the easiest of the trio to catch and permit arguably the hardest to fool. If you are getting good shots at permit, it makes sense to persevere til you’ve got one before moving on to tarpon and bonefish.
