Is this walking distance from. The beach and are there any lighthouses near beach?

Oceanarium wasn't a far walk at all depending on what end of beach you're on. Its right on the main strip. But the entire strip is only about a 30 minute walk anyways. Hope this helps :)

Okay I did a Google search there are 3 all further up north. 1. Portsmouth Harbor Lighthouse 2. Bubble Lighthouse 3. Boon Island Light Hope this helps.
