Even if you are not a big fan of snorkeling, if you visit the Galápagos Islands, you have to do it. These photos from Los Túneles (The Tunnels) just off the coast of Isla Isabela help explain why it is a requirement.
The videos and photos were taken by the guide with his Go Pro. You may have to sit on the play button for a bit before the videos starts.

The middle pic below is an octopus.

The final pic is a Brown Noddy. Many were nesting near by.
And, it appears that Isabella is not under water, as the title suggests. Much to your dismay I'm guessing.
Unbelievable! A trip of a lifetime. The turtles are so graceful under the water. Is that you in the speedo?? 🤣
