The harbor has 64 slips and 24 moorings available for vessels up to 50 feet, boat ramps and water at most of the slips.
Haleiwa Small-Boat Harbor at the head of Waialua Bay is protected by a breakwater on the W at the entrance and a breakwater further inside; both are marked by lights on the outer ends.
The approach to the harbor is marked by lighted and unlighted buoys, lights and a 128.9° lighted range. The entrance channel leads SW and S between two breakwaters to a basin inside.
The harbor can be entered in all but the most violent storms although night entry is not recommended without local knowledge.
