Welcome to Terror Isle – the most immersive and terrifying traditional haunted house experience near Houston and Galveston. Our haunted attraction serves the Houston, Galveston, League City, and surrounding cites in Galveston County.

This Halloween season, descend into THE ABYSS – a cursed underwater world where lost treasure has unleashed a deadly plague. From blood-chilling pirate lore to shadowy corridors and ghostly shipwrecks, each step brings you deeper into the darkness.

Guests come to face the horrors that await on Terror Isle. You were warned not to open the chest. Now the plague hunts us all.

This is one of the scariest traditional walkthrough haunted houses – full of immersive sets, live actors, monsters, special effects, and unforgettable fear.

Be sure to purchase the “Ultimate Experience”. With this ticket you must journey through 2 escape rooms before you can even enter the haunted house! It is like being in a real-life pirate horror adventure! As a bonus, you also get a tarot reading from our fortune teller. No haunted house offers such an adventure for your crew!
