The tidal shifts are so large in Golfo San Jose that when the tide goes out a spit of land connects the “island” to the continent. With the low tide coming twice a day a person could walk across without even getting their ankles wet, tramp the island and return in a couple of hours. With high tide the spit is covered with water making it appear to be an inaccessible island once again, a geomorphological characteristic referred to as a Tombolo.
