Stockton Top Marina sits on the Grand Union Canal's Warwick and Napton section, positioned at the head of the Stockton flight of locks.

It serves as a practical stopping point for boaters navigating between Napton Junction and the Calcutt Locks, placing it on one of the main cruising routes linking the Midlands with southern England.

The marina offers boatyard facilities including diesel, coal, a pump-out station, and a water point. Boats can also wind (turn) here, making it a useful waypoint for those reversing direction on this stretch of the canal.
