San Juan Harbor
A compact portrait of Old San Juan and the channels opening into its sheltered bay.
The harbor entrance passes beside Old San Juan before opening into the wider bay. Puerto San Juan Light marks the approach with a group of three flashes, while red and green channel lights lead toward the docks and terminals. A portrait frame follows the passage from the ocean into the harbor.
