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 Kona, the bucket-list move is Big Island Manta Ray Night Snorkel — Kona's Signature Experience. Manta Ray Advocates Hawaii (Jack's Diving Locker) 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 Kona port day, each with the independent way to make it yours.
