Fish Pass is a sandy boat ramp and kayak launch located on Mustang Island State Park, accessed via a small bridge spanning the fish pass on Highway 361.

The entrance road is sandy with large depressions from rainfall, requiring vehicles with higher clearance; it serves as the primary access point for the Ashum Trail of the Mustang Island Paddling Trail system.

This site is popular for both kayaking and fishing, offering access to shallow-water fishing areas and nearby flats, though amenities are limited and the nearest supplies are approximately 17 miles away.
