Sea Quest Hawaii
Kailua-Kona, Kona
A Small-Boat Captain Cook Snorkel With a Full Hour at the Monument
Sea Quest Hawaii (its address block reads "Sea Quest Rafting & Snorkeling Adventures") runs snorkel tours from Keauhou Bay; the office is at 78-7138 Kaleiopapa Street in Kailua-Kona and daytime-tour parking is at 78-7106 Kamehameha III Road. Its Captain Cook Snorkeling Tour is 3 hours at $115 for adults and $105 for children 5 to 11, with snorkel gear, flotation, wetsuits and snacks, juice and water included, and a full hour of snorkel time at the Captain Cook monument. It leaves at 9:00 AM (check-in 8:45, back about noon) or 12:45 PM (check-in 12:30, back about 3:45), and on Wednesdays both leave 15 minutes earlier.
The site also lists a Deluxe Morning Kealakekua tour (4+ hours, $132 adult, with a second stop at Hōnaunau), a Premium Morning tour (4.5 hours, $152, with a deli lunch) and a South Kona expedition from $185. Minimum age is 5. The site says expectant mothers and people with regular back or neck pain should not go, guests climb an aluminum ladder, and many of the tours suit non-swimmers. Daytime tours need at least 6 guests. Cancel or change at least 48 hours ahead; inside 48 hours you pay full price, and Sea Quest refunds in full if it cancels for weather. Taxes are not stated and an "Ocean Stewardship Fee" is mentioned without an amount.
