Route Schematic
Route Schematic — Three Snorkel Stops
The outing visits three primary snorkeling sites down South Kona, with opportunities to explore coastal caves and rare, boat‑only shoreline features.
Kealakekua Bay
Snorkel inside the 315‑acre marine sanctuary and view the monument to Captain Cook placed there in 1874.
Puʻuhonua O Hōnaunau
A culturally significant shoreline stop offering clear water snorkel opportunities adjacent to historic coastal features.
Remote Third Location
A boat‑only site — perhaps a black sand beach, stone arch, or dramatic lava formation — reachable only by the operator’s vessels.
This is an active snorkel outing; expectant mothers and individuals who experience regular back or neck pain are not eligible to participate, and the operator may alter stops for safety or sea conditions.
What the day feels like
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.
THE SANCTUARY
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.
THE SHORELINE
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.
THE WILDLIFE
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.
