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 Elizabeth Bay (Isabela), the bucket-list move is Los Túneles (Cabo Rosa): Snorkel the Lava Arch Labyrinth. Isabela Dive Center (official Isabela-based operator) 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 Elizabeth Bay (Isabela) port day, each with the independent way to make it yours.

3wildlife
Fins on, enter a glassy lava channel where dozens of white-tip reef sharks rest motionless in the shallows — then surface to walk among marine iguanas, Galápagos penguins, and sea lions on the black obsidian shore. This is Galápagos wildlife at its most intimate.

4scenic
Paddle and drift by silent panga through the emerald mangrove channels of Elizabeth Bay — the very anchorage your ship uses — encountering Galápagos penguins, nesting sea turtles, spotted eagle rays, and Pacific green sea turtles without ever setting foot on land.

5water
Step off a wooden dock into a warm, crystalline lagoon where sea lions play inches from your mask, Pacific green sea turtles graze on algae below you, and Galápagos penguins dart past like torpedoes. The ultimate free-entry snorkel — but best experienced with a private naturalist at golden hour.
Book it withSoleq Travel (licensed Isabela island specialist)USD 50–70 per person for a private naturalist-guided session (lagoon entry itself is free; fee covers guide and premium gear)
