Jump On In – The Water at Ahalanui is Fine


Have you ever dreamt of a bathtub so huge you didn’t have to worry about propping your feet up just to get some part of you submerged or your back getting cold on the wall behind you while your feet take a soak? Have you thought about floating endlessly in crystal clear salt water with a few of your closest friends or family members with no undertow to worry about? What about a few fishy friends? Yes? Well then welcome to Ahalanui pool.

Pele, goddess of the volcano, heats up this local man-made swimming spot in Kapoho just south of Hilo. This isn’t your mama’s backyard swimming pool though. These volcanically heated waters can get to above 90 degrees Fahrenheit. When the tide rushes in the spring-fed water mixes with the colder ocean water, but you can always find a toasty spot.

Steps led into the pool and a shallow ledge along the parameter make it easy for families to enjoy the pool together

This local attraction was one of those magical places that comes together as a kid and parent friendly spot. Mike could do some swimming and check out the fish that had taken up residence. Dek could still stand on his own feet in the water and splash around. I could relax on the edge, in arms reach of Dek, checking out the fish as they swam by. There were signs that warned of eels in the pool, but we never saw one.

The pool can get crowded, or so they say, but on a weekday morning we only came across one other family, a few people getting in a few laps and some fellow travelers taking a soak. There was more than enough room for all of us. Dek could splash until his heart content without bothering a soul.

Sometimes a little jumping is all a boy needs

A shallow ledge lined most of the pond; the perfect spot for Dek to throw rocks from. He could also use the ledge as a launching point to jump into his dad’s arms.  The water got deep, about 5 feet in most spots, pretty quickly, so we kept a life vest on Dek for most of our visit. This way I could I enjoyed lounging on the ledge just soaking up the warm water without the constant fear of Dek falling in and drowning.

Over the man-made wall the waves crashed but our water stayed nice and calm. Oddly enough is was pretty quiet too. We enjoyed our family soak with our fishy friends and just basked in the glory of island life. I’m not sure we would ever be ready to leave.

Cold ocean waters rush into the swimming pool creating a salty mix of warm water worth soaking in

    Sounds like my kind of pool!

    Looks like so much fun! I love the idea of warm water to swim in- I hate being cold!

  • Lisa

    Beautiful – and my kind of swimming spot! My kids laugh at me because I have trouble getting into our pool unless the heat is cranked right up. 90 degrees sounds just about right! 🙂

  • Sabrina

    This is so beautiful! … the view of the ocean in the back, the palm trees surrounding the pool, …. makes me dream of being there right now.

  • Leigh

    We spent some time in this place too – and I remember very warm water. I’d totally forgotten about it until I saw your photo. Thanks for the memory.

  • Dick Jordan

    Interesting! Must have driven right by the place when I was on the Big Island.

    What a beautiful spot. Way too warm for me, but I’m thinking my kids would probably love it. Great face plant by Dek into the water there too. That kid’s got a whole lot of daredevil in him.

      Dek has NO fear when it comes to water. I wish he had a little more actually. And jumping was a new thing for him on this trip so he had to try it out. A lot.

    I’ve only spent a few days on Big Island but I feel like I need to go back and sped at least two weeks just to catch the highlights! Thanks for sharing this gem!

      We spent a week on each side of the Big Island and it still wasn’t enough time to catch all of the highlights. Just another reason to go back I guess. I love places that can continue to show you new things every time you visit.

    I really dig this!

  • Mary @ The World Is A Book

    Beautiful! This is my kind of pool! Your posts on the Big Island make me want to go back and visit for an extended period. We missed a lot of things. Visiting this on a cruise just doesn’t cut it.

      Thanks for the heads up. I’m still working out the kinks of the new design. Happy Photo Thursday!
