Monsters Fishing - IT Monster Lake

Monsters Fishing Guide offers exciting adventures for anglers of all skill levels and expertise to IT Monster Lake. Enjoy the thrill of fishing one of the world’s largest stock ponds full of the best Amazon species.

IT Monster Lake is known far and wide as one of the best places in Thailand to catch Amazon Redtail Catfish, which can reach sizes of over 40 kg (88 lbs) in this lake! While you can pretty much count on hooking one of these striking fish, you may also come face to face with a variety of other ferocious freshwater predators. The list includes Arapaima, Pacu, Alligator Gar, huge Cheow Phraya Catfish, Tiger Shovelnose Catfish, and many more.

An experienced team with thousands of hours of professional experience will guide you through those productive waters. They will put their talent to work for you and will assist you throughout the trip as you get ready to tackle the biggest freshwater fish of your life!

Your guided trip will include the use of all rods, reels, tackle, and live bait, as well as fishing licenses. The guides will also offer some savory snacks, bottled water, and sandwiches for your group.

Don’t hesitate to bring your whole family with you. Fishing will be done from the shore or the docks. The crew will gladly pick you and your party up at the hotel and take you to the fishing grounds.

A day out with Monsters Fishing Guide is exactly what the doctor ordered for any freshwater enthusiast. If you feel like doing something special on your next vacation in Thailand, there is hardly a better thing to do!
