Naval Amphibious Base Pool is a military aquatics facility on NAB Coronado at Vella La Vella Road, providing lap swimming, aquatic training, and water-fitness programming for active-duty service members, dependents, retirees, and authorized DoD personnel in the 92118 ZIP. Access requires valid military identification and current base privileges, restricting the pool to the NAB Coronado population rather than the general public. The facility complements the broader MWR fitness infrastructure on base, including the VADM Martin Fitness Center at nearby Naval Air Station North Island, which runs weight rooms, cardio equipment, and group fitness classes under the same Navy Morale, Welfare, and Recreation program. NAB Coronado occupies the southern portion of Coronado Island along the Silver Strand, housing Naval Special Warfare Command and Basic Underwater Demolition/SEAL (BUD/S) training — a mission profile that makes aquatic conditioning a core requirement for the base population rather than a recreational add-on. Lap lanes accommodate individual swim workouts, unit physical training sessions, and swim qualifications that feed into fleet readiness requirements for expeditionary forces. The base's location on the Silver Strand corridor puts it between the civilian village of Coronado Island to the north and Silver Strand State Beach to the south, with the Coronado Bridge and North Island Naval Air Station anchoring the island's northern end. Off-duty recreation beyond the pool extends to the VADM Martin MWR Liberty Center, which programs entertainment, social events, and personal-enrichment activities for junior enlisted sailors in a substance-free environment. Service members seeking public-access aquatics for family use can direct dependents to Brian Bent Memorial Aquatics Complex at 818 Sixth Street or Crown Cove Aquatic Center at 5000 CA-75 for civilian pool and watercraft-rental options on the island.
