There is no single universally agreed-on number, but most expert coastal and navigation sources put it in the mid‑teens. The Texas coast has roughly 15–17 major tidal passes/inlets that cut through the barrier islands and connect the Gulf of Mexico to bays and the Intracoastal Waterway.

What “passes” means here

Along the Texas coast, “passes” usually refers to:

  • Natural or dredged inlets through barrier islands.
  • Channels that allow exchange between the open Gulf and inland bays/ICW.
    These are the cuts that ships, fishing boats, and tidal flows use to move between protected waters and the Gulf.

Why the number varies

Different sources count slightly differently:

  • Some list about 15 passes used in navigation between the Gulf and the ICW.
  • Others describe 16–17 inlets or passes along the Texas barrier islands, including some that are shallow, unstable, or lightly used.
  • A few minor cuts or former passes may be omitted if they are silted in or no longer navigable.

Practical takeaway for “how many”

If someone asks “how many passes are there on the Texas coast?”:

  • A defensible general answer is “around 16” , acknowledging a range of 15–17 depending on how minor or non‑navigable cuts are counted.
  • For navigation or boating purposes, guides often focus on about 15 primary passes that link the Gulf to sheltered waters.

Notable examples

Some of the better‑known Texas coastal passes include:

  • Sabine Pass, Bolivar Roads, San Luis Pass, and Brazos Santiago Pass.
  • Several others like Aransas Pass and Matagorda Ship Channel that are key for commercial and recreational traffic.
