Here’s the bucket list for your day ashore: the most extraordinary thing to do at each stop, and the private, small-group, or expert-led way to make it yours — your own pace, real access, none of the crowd.
In port at Kailua-Kona, the bucket-list move is Manta Ray Night Snorkel: Kona's Iconic After-Dark Encounter. Manta Ray Advocates / Jack's Diving Locker (Kona) runs it — a private, expert-led experience at your own pace, not a 40-person coach. Below: all 6 bucket-list things to do on a Kailua-Kona port day, each with the independent way to make it yours.

Glide above giant Pacific manta rays — some with 14-ft wingspans — as they barrel-roll through bioluminescent plankton clouds beneath your mask. This after-dark snorkel off Keauhou Bay is Kona's single most extraordinary marine experience.
