Inshore Mastery: Fishing the Crystal Flats with Captain Cliff Fleming
In the world of coastal angling, experience isn't just a number—it’s a roadmap, a tide chart, and a secret lure all rolled into one. For those looking to unlock the legendary fishing grounds around Port Isabel, Texas, there is one name that stands out as the area's undisputed master: Captain Cliff Fleming of Crystal Flats Guide Service. With a staggering over 50 years of fishing experience in these exact local waters, Captain Cliff doesn't just run a charter; he offers an immersive, educational, and thrilling angling adventure that few guides can match.
This deep connection to the flats and the backcountry, spanning over four decades of professional guiding alone, means Captain Cliff knows precisely where the fish are holding, regardless of the season, the tide, or the weather. He has logged thousands of hours perfecting his techniques, understanding the subtle shifts in the ecosystem, and, most importantly, identifying the "hideouts and tricks" of the area’s most sought-after game fish. For the client, this translates into an unparalleled competitive edge. When you book a trip with Crystal Flats, you’re not spending precious time searching; you’re spending time catching. Aboard his meticulously outfitted vessel, you’re in for a day that promises to be both a challenging pursuit of trophy fish and a relaxing, comfortable day on the water.
The Vessel: Engineered for the Flats
The foundation of any successful shallow-water charter is the boat, and Captain Cliff has chosen a true specialist: the 2022 24-foot Shallow Stalker Pro Cat. This machine is specifically engineered for the demanding Texas flats and bays, offering the perfect combination of shallow draft capability and superior comfort.
The Shallow Stalker Pro Cat is an impressive sight, but its performance. is what truly sets it apart. Powered by a robust 250 HP Yamaha SHO 4-stroke engine, the boat delivers exceptional control on the flats.

Capt Cliff greeted in the morning with a smile! Capt CIiff is laid back and keeps a level of professional skill in his trade. He gave us some basic tips and other tips of knowledge, remembered and used our names (maybe he had a post-it but it feels good that someone took the time to do this). My dog was allowed to go fishing with me which just brought joy to my heart. We caught multiple fish thanks to Capt Cliff working to keep us on them. I had such a great time and would highly recommend!

Captain Cliff was a great guide for us. He did wonderfully with my 11 year old. We hooked in several fish and brought quite a few back. I highly recommend Cliff.

I had the best experience with my two twenty something sons. We caught our limit in 2 hours, what an awesome day! Captain Cliff was very knowledgeable and obviously knows how to fish, and made it fun.
