A scattered field of corroded steel plate, ribs, and machinery directly off the cruise tender pier, in 30 to 40 feet of water. The Balboa is no longer a coherent shipwreck — it was deliberately blown apart in the 1950s — but the resident schools of fish, the proximity to shore, and the easy depth make it a popular night dive when the cruise ships have left.
Access is via local dive operators only; you cannot dive it without checking in for harbour traffic. Most dive trips combine the Balboa with the Cali nearby.
