Expedition South Kona: Three-Pronged Snorkel Along the Wild Big Island Coast.
Embark from Keauhou Bay for a compact, five‑hour outing that threads 22 miles down the South Kona coast and stops at three distinct snorkeling locations — including the 315‑acre marine sanctuary of Kealakekua Bay and the culturally significant Puʻuhonua O Hōnaunau — where sea caves, lava formations and vibrant reef life define the day.

Outing Highlights
Kealakekua Bay: Monument, Marine Sanctuary and Clear Water
One of the morning stops is Kealakekua Bay, a 315‑acre marine sanctuary where the monument to Captain Cook stands; the protected waters here are among the trip's focal snorkeling sites.
Puʻuhonua O Hōnaunau and Remote Coastal Geology
The itinerary includes the culturally important Puʻuhonua O Hōnaunau and a third, remote location reachable only by boat — places where black sand pockets, stone arches and ancient lava formations punctuate the coastline.
Marine Encounters: Turtles, Dolphins and the Chance of Whales
Throughout the morning the crew scouts for marine life — Hawaiian spinner dolphins, green sea turtles and even pilot whales when conditions allow — making wildlife viewing a running theme between snorkel stops.

What the Morning Feels Like
The day moves with purposeful brevity: a short run from the harbor to each snorkel anchor, guided entries into clear pockets of reef and time to explore sea caves and lava tubes from a maneuverable vessel, followed by a shaded deli lunch served with views of the Captain Cook monument — all arranged so you arrive in a swimsuit with reef‑safe sunscreen and a towel and leave with a still‑wet memory of Kona’s coastline.
