Sea cave and lava-tube cruise (weather permitting)
If sea state and visibility allow, the captain will detour to nearby sea caves and lava tubes for up-close coastal geology viewing; otherwise the schedule favors extra snorkel time.
Return to harbor
A calm return run back to the boat launch closes the outing after the day’s snorkel and coastal segments.
This outing requires basic water competence (swimming and treading water), the ability to climb a boat ladder and meet the operator’s fitness and weight limits; sea-cave stops are subject to safety and weather conditions.
