Swimming with turtles was high on my things-to-do-in-Hawaii list.
I had looked into a few specifically turtle spotting boat trips but then one day while walking along Laniakea Beach in Haleiwa, we found 'em in the wild.
We were so enthralled by our first spotting that we sat next to it for a solid hour gently poking at it, whispering "Look at it's eye!", "Touch it's tail and see what it does!" and being generally annoying human tourists.
Technically, you aren't supposed to touch the turtles (we didn't see the sign until after our first turtle... and then we ignored it) BUT HOW COULD YOU NOT TOUCH THESE MASSIVE INCREDIBLE PRE-HISTORIC LOOKING BEINGS.
Walking along the beach, we spotted more and more washed upon the shore. And then we came back day after day, to swim with them in the ocean.
So, if you ever find yourself on the island of the Oahu... skip the $80 "swim with the turtles" boat tour and just hang with them at Laniakea Beach.
