Gas Chambers

Aguadilla, Puerto Rico
🪸Sharp reef⚠️Shallow😮‍💨Hold-downs

Gas Chambers lives up to its name—a heavy, hollow reef break that produces some of the most intense tubes in the Caribbean. Located on Puerto Rico's northwest coast near Aguadilla, the wave jacks up over shallow reef and throws thick, square barrels. Not for the faint of heart, but when it's on, it's one of Caribbean's most intense experiences.
