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 Reykjavik, the bucket-list move is Inside the Volcano: Descend into Þríhnúkagígur's Magma Chamber. Reykjavik Excursions (RE) 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 Reykjavik port day, each with the independent way to make it yours.
